monitorix.conf(5) Monitorix configuration file monitorix.conf(5) NAME monitorix.conf - Configuration file for Monitorix. DESCRIPTION Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used on production Linux/UNIX servers, but due to its simplicity and small size may also be used to monitor embed- ded devices as well. It consists mainly of two programs: a collector, called monitorix, which is a Perl daemon that is started automatically like any other system service, and a CGI script called monitorix.cgi. Since 3.0 ver- sion Monitorix includes its own HTTP server built in, so you don't need to install any web server to use it. Every time monitorix is started it reads the configuration file from the path specified in the command line (using the -c option), and once checked, it creates the index.html file that will act as the Monitorix main page. It also creates a file called <base_dir>/cgi/monitorix.conf.path that includes the absolute path of the configuration file. This file will be read by monitorix.cgi to determine the exact location of the configura- tion file. CONFIGURATION OPTIONS IMPORTANT NOTE: these options have default values that might vary de- pending on your operating system. Please check the configuration files in /etc/monitorix/conf.d/. Blank lines are ignored, and whitespace before and after a token or value is ignored as well as tabulators, although a value can contain whitespace within. Lines which begin with a # are considered comments and ignored. If you want to comment out a large block you can use C-style comments. A /* signals the begin of a comment block and the */ signals the end of the comment block. If an option has multiple values their must be separated by comma. title A free description of the server; where it is located, the Com- pany name, etc. Default value: Place a Title Here hostname The name of the host. Default value: theme_color RRDtool comes with a default white theme, and since Monitorix introduces its own black theme, you have two predefined themes to choose from. Default value: black refresh_rate The refresh rate (in seconds) of the statistics web page dis- played in your browser. If set to 0, page refreshing is dis- abled. Default value: 150 iface_mode The interface mode defines the manner in which data is shown in the browser. Since version 1.4.0 it has been possible to display the graphic data using plain text tables. This allows Monitorix to be used by those running screen reader software, and also simplifies automatic data processing through scripts. The possible values are: graph for rendered graphs. text for plain text representation. Default value: graph enable_zoom Zoom allows double clicking any graph in order to see a larger version (zoomed in). This is especially useful for seeing addi- tional detail. Default value: y netstats_in_bps This option toggles network values between bits (bps) and Bytes (Bps) per second. By default the values will be shown in Bytes per second (Bps). Default value: n netstats_mode This option toggles network visualization mode between over- lapped (input and output values appear one in front the other) and separated (input values appear on top and output values be- low, in negative). Default value: overlapped disable_javascript_void This option enables or disables the use of javascript:void-URLs when opening windows with zoomed graphs. Some people likes to open links in the background by pressing the middle mouse button in Firefox, and with the default javascript:void-URLs the only they get is an empty window with nothing in it. Default value: n temperature_scale This option toggles between values in Celsius or in Fahrenheit in those graphs that represent temperatures. The possible values are: c for Celsius. f for Fahrenheit. Default value: c show_gaps This option, when enabled, shows the gaps (missing data) in the graphs. This is specially useful to detect if the server or Mon- itorix were stopped for a while, or any other unavailability. In order to be able to locate those gaps easily in each graph, it uses the white color in the default black theme and the black color in the white theme. These default colors are defined in monitorix.conf so they can be changed as any other option. Default value: n global_zoom This option zooms all the graphs (including the legend's font size) by the given amount. The factor must be greater than 0 and it accepts decimal values. This is specially useful for people with big screens that either want to avoid using the browser feature to zoom the contents of the window and for those that watch the graphs from certain dis- tance. Keep in mind that the contents of the graphs remains with the same detail level all the time, and that it doesn't affects to the standard zoomed graph that appears when clicking in the pic- ture. Default value: 1 max_historic_years This option defines the maximum number of years of historical data in all graphs. WARNING: Every time this value is extended Monitorix will resize every .rrd file accordingly, removing all historical data. There is no longer any upper limit for this value. Default value: 1 accept_selfsigned_certs This option forces to accept self-signed certificates when col- lecting values remotely using HTTPS protocol. Default value: y priority Sometimes when a server is under heavy use, Monitorix might be unable to collect some statistical data due to its normal prior- ity (0 by default). This makes monitoring useless because graphs are empty during that hard period of time. In order to mitigate this situation this option sets the prior- ity in which Monitorix will be scheduled by the kernel. The ac- cepted range of values is the same as in the setpriority() sys- tem call: that is, from -20 (maximum priority) to 19 (lowest priority). Default value: 0 image_format This is the format of each generated graph. There are only two possible values: PNG and SVG. Default value: PNG enable_parallelizing This option will fork an independent process for each graph in order to speed up graph generation in multi-core systems. It's best to keep it disabled on unicore processors. Default value: y enable_rrd_lock This option will synchronise the rrd file access by creating the file /tmp/monitorix.lock and use it via flock. The read lock during the cgi call can be disabled on a per call basis via set- ting the environment variable INHIBIT_LOCKING. This is useful for modules that call the cgi function internally. Default value: n enable_relative_urls This option will change all URLs in the graphs to relative, in- stead of absolute URLs. Default value: n include_dir The main configuration file is usually called monitorix.conf and its location is provided as part of the command line arguments. In addition, other configuration files may be loaded placing them in the directory pointed by this option. The names must end with .conf to be included. This option is mainly intended to include third-party modules with their own configuration files without having to modify any file from your Monitorix installation. All modules are located in /usr/lib/monitorix (in some operating systems that path can change). All the configuration files in there will be loaded in alpha- betic order, so the last file loaded will overwrite any previous option. Default value: /etc/monitorix/conf.d additional_graph_name This is an optional configuration option for configuration files in include_dir. It takes a comma separated list of additional modules that is appended to the graph_name option. This enables you to add custom modules without changing the monitorix.conf or copy all names from graph_name to your config file. Default value: None ip_default_table This option will define in which table Monitorix will put all iptables rules for network traffic accounting monitoring. It only works on Linux. Although this is a global option, only the graphs port, nginx and traffacct are affected by it. Default value: filter ipv6_disabled This option enables or disables the use of the ip6tables com- mand. It only works on Linux. Although this is a global option, only the graph port is cur- rently affected by it. Default value: n url_prefix_proxy This option forces monitorix.cgi to bypass the URL building. This is specially useful when Monitorix is used behind a reverse proxy. An example would be: http://myexternalwebsite.com Default value: enable_hourly_view This option enables or disables the ability to select the hourly view in the main page. No .rrd file will change by selecting this option and the his- torical data won't be affected. Default value: n user_agent_id This option defines the string to be used to identify Monitorix in the HTTP requests. Its value will be sent as the "User-Agent" header. The default value will depend on the current Perl version in your system. An example would be libwww-perl/5.833. enable_back_button This option enables or disables the ability to go back to the main page from the graphs page without using the browser's back button. It will show a back arrow in the upper-left corner and it is specially useful for people using the browser in full-screen mode. Default value: n rrdtool_extra_options This option permits create a comma-separated list of RRDtool op- tions that will be included in all graphs. This is specially useful if you want to take advantage of an specific RRDtool graphics option. An example would be: rrdtool_extra_options = "--grid-dash=1:0, --no-legend" use_external_firewall By default, Monitorix creates a set of iptables rules to collect the amount of network activity that some graphs (port.pm and ng- inx.pm) need. This might be a problem for people using an exter- nal firewall that could eventually remove such iptables rules created by Monitorix. In these cases, you may want to set this option as y to tell Monitorix to not create such iptables rules, but expect that they will be already created by an external software. Keep in mind that the rule names created in your firewall must coincide with the names that Monitorix expects to find for each case. Familiarize yourself with the iptables rules created auto- matically by Monitorix before enabling this option. Default value: n base_dir This is the absolute path to the directory where all the web el- ements are located: cgi/ directory where resides monitorix.cgi. imgs/ directory for the .png graph images. index.html Monitorix main page. logo_bot.png Monitorix bottom logo. logo_top.png Monitorix top logo. monitorixico.png Monitorix favicon logo. Default value: /var/lib/monitorix/www/ (depends on the operating system) base_lib This is the absolute path to the directory where all of the monthly reports, daily traffic usage, and RRD files are located: reports/ monthly reports localization directory. usage/ daily traffic usage data directory. *.rrd RRD files. Default value: /var/lib/monitorix/ (depends on the operating system) base_url This is the URL prefix that Monitorix utilizes when referring to its own pages and files. Default value: /monitorix base_cgi This is the URL prefix that Monitorix utilizes when referring to monitorix.cgi. Default value: /monitorix-cgi HTTP built-in server enabled This enables or disables the HTTP server that Monitorix has built-in. This is specially useful for system administrators that don't want to install a web server (Apache, Lighttpd, Ng- inx, etc.) to see the Monitorix graphs. Default value: y host This option takes an optional host address for this server to bind to. If none is specified (default) it will bind to all in- terfaces. Default value: port This is the network port from where the HTTP server will listen on. Default value: 8080 user/group This sets the user and group that the HTTP server will run as. Default value for user: nobody Default value for group: nobody log_file This is the path to the HTTP server log file. If you leave this option blank or undefined Monitorix will log using the standard file descriptors. This is specially useful on systemd-based systems, you'll need to use the command journalctl -u monitorix to see the logs. Default value: /var/log/monitorix-httpd hosts_deny This is a comma delimited set of IP addresses which are not per- mitted to access Monitorix graphs. There is the special keyword called all that can be used to deny all IP addresses. The access control uses the same approach as in the TCP-Wrap- pers; the search stops at the first match: - Access will be granted when an IP address matches an en- try in the hosts_allow list. - Otherwise, access will be denied when an IP address matches an entry in the hosts_deny list. - Otherwise, access will be granted. Default value: hosts_allow This is the opposite of hosts_deny option. IP addresses listed here are permitted to access Monitorix graphs. There is also the special keyword called all that can be used to allow access to all IP addresses. Default value: https_url This will force to use the prefix https:// in all links. This is special useful if you plan to use a reverse-proxy HTTPS server in front of the Monitorix HTTP built-in server. Default value: n autocheck_responsiveness There is a well known problem with the HTTP built-in server that Monitorix implements using the Perl module 'HTTP::Server::Sim- ple'. It looks like it's pretty weak to the common attacks that any web server receives every day. As a consequence of that, it just hangs, and when you want to see the stats of your server, you just see your browser waiting for a response that never comes, which ends up with a timeout. In these cases, you are forced to login to your server and restart Monitorix, in order to refresh the HTTP built-in server. So in order to mitigate (hopefully) all this annoying hangups, this options acts like an autocheck to control the responsive- ness of the HTTP server on every minute, and in case of no re- sponse then it will be restarted automatically. Default value: y HTTP built-in server with access authentication enabled This enables or disables the authentication mechanism to control access to pages and other resources. The only allowed mechanism is Basic and uses the 401 status code and the WWW-Authenticate response header. It's highly recommended to set this option according your needs before start Monitorix. For more information about the Basic access authentication mech- anism and its security implications, please refer to http://en.wikipedia.org/wiki/Basic_access_authentication. Default value: n msg This option sets the Realm to be used in the authentication. That message should appear in the client dialog box to help user to identify the secure area. Default value: Monitorix: Restricted access htpasswd This option sets the path to the password file that was created with the help of the htpasswd.pl script. That script encrypts and validates passwords using the system's crypt() routine. If your Monitorix package doesn't come with that script, you may use the similar htpasswd(1) program provided with the Apache web server. The format of the password file consist of one or more lines with a username and password separated by a colon. The following is an example of a password file: paul:oGkEsQK6RYIII peter:HF1r7qRL4Kg6E Since the script uses the crypt() algorithm, only the first 8 characters of the password are used to form the password. If the supplied password is longer, the extra characters will be silently discarded. WARNING: don't use the character colon ':' as part of your name or password since this character is used as field separator. Default value: /var/lib/monitorix/htpasswd hosts_deny This is a comma delimited set of IP addresses which will be forced to do authentication. There is the special keyword called all that can be used to deny all IP addresses. The access control uses a similar approach as in the TCP-Wrap- pers; the search stops at the first match: - Access will be granted when an IP address matches an en- try in the hosts_allow list. - Otherwise, access will be denied when an IP address matches an entry in the hosts_deny list. - Otherwise, access will be denied (if not defined it will deny all hosts). Default value: all hosts_allow This is the opposite of hosts_deny option. IP addresses listed here will bypass the authentication mechanism (even when it is enabled). It helps in specific cases like to avoid to have to include the auth credentials in the url_prefix of the emailre- ports module. There is also the special keyword called all that can be used to allow access to all IP addresses. Default value: Log files pathnames log_file This is the path of the Monitorix log file. Please check this file periodically and especially after every update to confirm proper operation. If you leave this option blank or undefined Monitorix will log using the standard file descriptors. This is specially useful on systemd-based systems, you'll need to use the command journalctl -u monitorix to see the logs. Default value: /var/log/monitorix secure_log This is the path to the system log (also known as auth.log, etc.) Monitorix uses this file to report SSH, POP3, FTP and Tel- net successful logins. Default value: /var/log/secure mail_log This is the path to the mail log file. Monitorix uses this file to report messages sent (supporting Sendmail and Postfix for- mats), and the MailScanner log format for spam-mail and virus- mail alerts. Default value: /var/log/maillog milter_gl This is the path to the dump file of milter-greylist. Default value: /var/milter-greylist/greylist.db imap_log This is the path to the IMAP (Dovecot or UW-IMAP) log file. Mon- itorix uses this file to report IMAP and POP3 successful logins. Default value: /var/log/imap hylafax_log This is the path to the Hylafax log file. Monitorix uses this file to report successful FAX dispatches. Default value: /var/spool/hylafax/etc/xferfaxlog cups_log This is the path to the CUPS page log file. Monitorix uses this file to report on print jobs. Default value: /var/log/cups/page_log ftp_log This is the path to the FTP server (ProFTPD, vsftpd or Pure- FTPd) log. Monitorix uses this file to report FTP successful lo- gins and other FTP-related information. Default value: /var/log/proftpd/access.log fail2ban_log This is the path to the Fail2ban log file. Monitorix uses this file only if the option graph_mode has the value rate. Default value: /var/log/fail2ban.log spamassassin_log This is the path to the Spamassassin log file. Monitorix uses this file to report spam-mail alerts. Default value: /var/log/maillog clamav_log This is the path to the Clamav log file. Monitorix uses this file to report virus-mail alerts. Default value: /var/log/clamav/clamav.log cg_logdir This is the path to the CommuniGate logs directory. Monitorix uses these files to report the number of mail messages success- fully received and sent, and to report IMAP and POP3 successful logins. Default value: /var/CommuniGate/SystemLogs/ squid_log This is the path to the Squid log file. Monitorix uses this file to report on Squid Proxy requests. Default value: /var/log/squid/access.log imap_log_date_format This is the Dovecot date format as it appears in the imap_log file. Default value: %b %d secure_log_date_format This is secure_log date format. Default value: %b %e Piwik tracking code enabled This enables the inclusion of the Piwik tracking code in the main index.html file. Please refer to http://pi- wik.org/docs/tracking-api/ for more information on how to fill these fields. Default value: n Enable or disable graphs graph_enable This enables or disables the monitoring of each graph. Placing a y on a desired graph and restarting Monitorix will automatically create the RRD file for that graph and start gathering informa- tion according to its settings. System load average and usage (system.pm) This graph shows information about system load average (classical UNIX triplet), memory allocation, active processes (on Linux brought di- rectly from the /proc directory), entropy and the system uptime. loadavg_enabled This section enables or disables the alert capabilities for this graph. Only the alert for the average CPU load is currently im- plemented. It works as follows: This alert uses the minimum value between the second and the third load averages (those that represent the last 5 and 15 min- utes), and if it reaches the loadavg_threshold value for the in- terval of time defined in loadavg_timeintvl, Monitorix will exe- cute the external alert script defined in loadavg_script. The idea to use min(load5, load15) is to obtain a more symmetric curve and a sooner cancellation of the alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n loadavg_timeintvl This is the period of time (in seconds) that the threshold needs to be exceeded before the external alert script is executed. Default value: 3600 loadavg_threshold This is the value that needs to be reached or exceeded within the specified time period in loadavg_timeintvl to trigger the mechanism for a particular action, which in this case is the ex- ecution of an external alert script. The value of this option is compared against the last 15 minutes of CPU load average. Default value: 5.0 loadavg_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in loadavg_timeintvl. 2nd - the value currently defined in loadavg_threshold. 3rd - the current 15min CPU load average. Default value: /path/to/script.sh time_unit This is the unit in which will appear the values in the uptime graph. Possible values are: minute, hour or day. It will default to day even if none is specified. Global kernel usage (kern.pm) Note that the VFS graph is just informative of how the kernel is bal- ancing its tables. graph_mode This changes the layout of the kernel usage graph, the possible values are r for a real graph, or s for a stacked graph (every line or area is stacked on top of the previous element). Default value: r list This is the list of values offered in modern Linux kernels. Older Linux kernels or other Operating Systems may not have all of them. Placing a y or an n will enable or disable the value in the graph. Kernel usage per processor (proc.pm) max This is the number of processors or cores that your system has. There is no limit, however keep in mind that every time this number is changed Monitorix will resize the proc.rrd file ac- cordingly, removing all historical data. Default value: 4 graphs_per_row This is the number of processor graphs that will be put in a row. Consider the interaction of this parameter with the size and data options (below) in order to adjust the size and number of graphs in relation to your horizontal screen size. Default value: 2 size This option sets the size of all processors graphs. The possible values are: large for 750x180 graphs. main for 450x150 graphs. medium for 325x150 graphs. medium2 for 325x70 graphs. small for 200x66 graphs. mini for 183x66 graphs. tiny for 110x40 graphs. Default value: medium DATA This option will completely enable or disable the legend in the processor graphs. Default value: y AMD power consumption (amdenergy.pm) This graph is able to monitor the power draw of an unlimited number of AMD CPUs if the amd_energy driver and sensors is available. I will show power draw of the cores and the socket and the non-core part of the power draw. It is calculated by subtracting the sum of the core power draw from the socket power draw. list This is a list of groups of CPU sensors you want to monitor with the same names as they appear in your sensors(1) command. Each group will become a plot and there may be an unlimited number of groups. You can define device names like amd_energy-isa-0000. WARNING: Every time the number of groups or the size of the groups in this option changes, Monitorix will resize the amden- ergy.rrd file accordingly, removing all historical data. To collect the CPU power usage the energy counters from the sen- sors command via the amd_energy driver is used and a power con- sumption in the monitoring time interval calculated. It is recommended that you first check if the sensors output is able to provide energy counters (EcoreXXX and EsocketX) from the CPU(s) that you plan to monitor. For example check sensors for available sensors. You may test this with the following command (root privileges might be needed to access the energy counters): # sensors amd_energy-isa-0000 amd_energy-isa-0000 Adapter: ISA adapter Ecore000: 31.81 kJ Ecore001: 27.54 kJ Ecore002: 25.44 kJ Ecore003: 27.08 kJ Ecore004: 48.45 kJ Ecore005: 41.39 kJ Ecore006: 42.49 kJ Ecore007: 39.88 kJ Ecore008: 109.67 kJ Ecore009: 107.59 kJ Ecore010: 115.21 kJ Ecore011: 168.80 kJ Ecore012: 61.64 kJ Ecore013: 49.86 kJ Ecore014: 42.20 kJ Ecore015: 51.55 kJ Ecore016: 35.41 kJ Ecore017: 35.87 kJ Ecore018: 33.91 kJ Ecore019: 34.40 kJ Ecore020: 102.11 kJ Ecore021: 238.25 kJ Ecore022: 86.68 kJ Ecore023: 99.13 kJ Ecore024: 23.79 kJ Ecore025: 23.30 kJ Ecore026: 23.48 kJ Ecore027: 23.63 kJ Ecore028: 23.53 kJ Ecore029: 22.10 kJ Ecore030: 20.83 kJ Ecore031: 19.45 kJ Esocket0: 21.12 MJ If you see good results as above, you can add it to the group 0 like this: <list> 0 = amd_energy-isa-0000 1 = amd_energy-isa-0001 </list> number_of_cores This list sets the number of cores for the CPUs specified in the list option. It is required to specify the number of cores is for each CPU in list <number_of_cores> amd_energy-isa-0000 = 64 amd_energy-isa-0001 = 32 </number_of_cores> map This list complements the list option. It basically allows you to change the CPU name that will appear in the graph, hiding the sensor name. If no association is defined, then Monitorix will display the name of the CPU device as it is specified in the config file. <map> amd_energy-isa-0000 = AMD CPU 1 amd_energy-isa-0001 = AMD CPU 2 </map> desc This list complements the list option. It allows you to include a title for every group of CPUs. The title will appear in the title above the plot. <desc> 0 = Socket 1 power distribution 1 = Socket 2 power distribution </desc> socketpower_enabled This section enables or disables the alert capabilities for this graph; the alert for the socket power draw. It works as follows: If the socket power draw of any of the specified CPU device reaches or succeeds the socketpower_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in socketpower_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n socketpower_timeintvl Not used in this alert. Default value: None socketpower_threshold This is the value that needs to be reached or succeeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: None socketpower_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in socketpower_timeintvl. 2nd - the value currently defined in socketpower_threshold. 3rd - the current socket power draw. Default value: /path/to/script.sh use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n Intel RAPL power consumption (intelrapl.pm) This graph is able to monitor the power draw of an unlimited number of Intel RAPL supporting devices like Intel CPU packages. For example it can (if the device RAPL data is available) show power draw of the cores, integrated GPU, package, DRAM and the non-core part of the power draw. The non-core power draw composition can be specified by setting which parts will be subtracted from the package power draw. list This is a list of groups of CPU sensors you want to monitor with an arbitrary name. Each group will become a plot and there may be an unlimited number of groups. You can define sensor names like ore and ackage. WARNING: Every time the number of groups or the size of the groups in this option changes, Monitorix will resize the intel- rapl.rrd file accordingly, removing all historical data. To collect the CPU power usage the energy counters from the in- tel-rapl framework are used and a power consumption in the moni- tored time interval calculated. It is recommended that you first check if the intel-rapl class tree and collect your desired energy counters from the devices that you plan to monitor. For example check tree /sys/class/pow- ercap/intel-rapl for available energy_uj energy counters. The corresponding name files helps identifying the sensors. You can add it to the group 0 like this: <list> 0 = core, uncore, package, dram 1 = dram </list> list_item_names This list complements the list option. It allows you to change the group name that will appear in the graph, hiding the sensor name. If no association is defined, then Monitorix will display the name of the device as it is specified in the config file. <list_item_names> 0 = CPU 1 1 = DRAM modules </list_item_names> sensors This list sets the energy counter files for the devices speci- fied in the list option. <sensors> core = /sys/class/powercap/intel-rapl:0:0/energy_uj uncore = /sys/class/powercap/intel-rapl:0:1/en- ergy_uj package = /sys/class/powercap/intel-rapl:0/energy_uj dram = /sys/class/powercap/intel-rapl:0:2/energy_uj </sensors> sensor_names This list complements the sensors option. It allows you to change the device name that will appear in the graph, hiding the device name. If no association is defined, then Monitorix will display the name of the device as it is specified in the config file. <sensor_names> package = Package core = Cores uncore = IGP dram = DRAM </sensor_names> package_sensors This list allows you to set a device name for the package de- vice. This specified device is used as total power draw to cal- culate the non-core power draw by subtracting the power draw of the devices specified for the same group in ackage_sensors. Non- core power draw will not be shown if no package sensor is speci- fied for a certain group. <package_sensors> 0 = package </package_sensors> package_content This list complements the package_sensors option. It allows specify the devices that are contained in the total package power draw. This information is needed if you want to visualize non-core power draw. Non-core power draw will be calculated by subtracting the sum power draw of a package content group from the package power draw. <package_content> 0 = core, uncore </package_content> noncore_names This list allows you to change the non-core name for a certain group that will appear in the graph legend. <noncore_names> 0 = Non-Core </noncore_names> desc This list complements the list option. It allows you to include a title for every group of devicess. The title will appear in the title above the plot. <desc> 0 = CPU power distribution 1 = Memory power distribution </desc> sum This list allows you to add a specific sum of devices to the plot of a certain group. No sum will be shown if not specified for the group. <sum> 0 = package, dram </sum> sum_names This list complements the seum option. It allows specify the name of the sum if desired. <sum_names> 0 = Package + DRAM </sum_names> packagepower_enabled This section enables or disables the alert capabilities for this graph; the alert for the package power draw. It works as fol- lows: If the package power draw specified by package_sensors of any of the specified device reaches or succeeds the package- power_threshold (the interval of time is not used here), Moni- torix will execute the external alert script defined in package- power_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n packagepower_timeintvl Not used in this alert. Default value: None packagepower_threshold This is the value that needs to be reached or succeeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: None packagepower_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in packagepower_timeintvl. 2nd - the value currently defined in packagepower_threshold. 3rd - the current package power draw. Default value: /path/to/script.sh use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n show_noncore_info This option, when enabled via y, enable showing description string in the legend how the non-core part is calculated. Default value: n max_number_of_values_per_group This option sets the maximum number of devices per group if more values are required. WARNING: Every time the max_number_of_values_per_group value changes, Monitorix will resize the intelrapl.rrd file accord- ingly, removing all historical data. Default value: 10 HP ProLiant System Health (hptemp.pm) list This list will hold the defined temperature sensors for each graph. You must have installed the command hplog that comes with HP ProLiant System Health Application and Command Line Utili- ties. Each graph has a limited number of IDs: graph_0 up to 8 IDs. graph_1 up to 6 IDs. graph_2 up to 6 IDs. The following is a configuration example of selected IDs: # hplog -t ID TYPE LOCATION STATUS CURRENT THRESHOLD 1 Basic Sensor Ambient Normal 75F/ 24C 107F/ 42C 2 Basic Sensor CPU (1) Normal 104F/ 40C 179F/ 82C 3 Basic Sensor CPU (2) Normal ---F/---C 179F/ 82C 4 Basic Sensor Memory Board Normal ---F/---C 188F/ 87C 5 Basic Sensor Memory Board Normal 82F/ 28C 188F/ 87C 6 Basic Sensor Memory Board Normal ---F/---C 188F/ 87C 7 Basic Sensor System Board Normal 89F/ 32C 192F/ 89C 8 Basic Sensor System Board Normal ---F/---C 192F/ 89C 9 Basic Sensor System Board Normal 84F/ 29C 192F/ 89C 10 Basic Sensor System Board Normal 118F/ 48C 230F/110C 11 Basic Sensor System Board Normal 96F/ 36C 192F/ 89C 12 Basic Sensor System Board Normal 84F/ 29C 154F/ 68C 13 Basic Sensor System Board Normal 87F/ 31C 154F/ 68C 14 Basic Sensor System Board Normal 89F/ 32C 156F/ 69C 15 Basic Sensor System Board Normal 93F/ 34C 161F/ 72C 16 Basic Sensor Ambient Normal ---F/---C 192F/ 89C 17 Basic Sensor System Board Normal ---F/---C 192F/ 89C 18 Basic Sensor SCSI Backplane Normal 32F/ 0C 140F/ 60C <list> graph_0 = 2, 3 graph_1 = 1, 5, 18 graph_2 = 7, 9, 10, 11, 12, 13 </list> alerts This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the temperature that needs to be reached or ex- ceeded within the specified time in time interval to execute the external script. The script is the full path name of the script that will be exe- cuted by this alert. Each defined sensor has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the first temperature sensor: <alerts> 2 = 3600, 40, /path/to/script.sh </alerts> Such alert means that if the value of the sensor number 2 reaches or exceeds 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the value of the sensor. LM-Sensors and GPU temperatures (lmsens.pm) list In this list you may specify the sensors you want to monitor with the same names as they appear in your sensors(1) command. For example, imagine a sensors(1) output like this: # sensors coretemp-isa-0000 Adapter: ISA adapter Core 0: +51.0C (high = +78.0C, crit = +100.0C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +49.0C (high = +78.0C, crit = +100.0C) f71882fg-isa-0a00 Adapter: ISA adapter 3.3V: +3.30 V Vcore: +1.21 V (max = +2.04 V) Vdimm: +1.82 V Vchip: +1.38 V +5V: +5.00 V 12V: +14.37 V 5VSB: +4.33 V 3VSB: +3.30 V Battery: +3.22 V CPU: 2035 RPM System: 1765 RPM ALARM Power: 2110 RPM ALARM Aux: 2080 RPM ALARM M/B Temp: +36.00 C CPU Temp: +29.00 C Then you may want to configure that list as: <list> core0 = Core 0 core1 = Core 1 mb0 = M/B Temp cpu0 = CPU Temp fan0 = CPU fan1 = System fan2 = Power fan3 = Aux volt0 = 3.3V volt1 = VCore volt2 = Vdimm volt3 = Vchip volt4 = \+5V volt5 = 12V volt6 = 5VSB volt7 = 3VSB volt8 = Battery gpu0 = nvidia </list> Note that you need to escape the plus and minus signs in the voltage labels. It also recommended to enclose the values using double quotes. The Fan values can be prefixed with the words rpm: (optional) or percent:. This will tell to Monitorix how to treat these values in the graph and in the case of the later it will add the per- centage symbol (%) right after the value. Just like this: <list> fan0 = percent:Power </LIST> The last one, gpu0, is set here just in case you have a sup- ported graphics card and want to monitor its temperature. Cur- rently only NVIDIA and ATI graphic cards are supported; with the values nvidia and ati respectively, and it requires the official NVIDIA or ATI drivers. If the temperature of your graphical card appears in the output of lm_sensors, then you can tell Monitorix to use it instead of using the official NVIDIA or ATI drivers. In that case, you need to prefix with lmsensors: the name of the temperature value. Just like this: <list> gpu0 = lmsensors:edge </list> This list has the following maximums allowed: Up to 16 core keys (from core0 to core15). Up to 2 mb keys (mb0 and mb1). Up to 4 cpu keys (from cpu0 to cpu3). Up to 9 fan keys (from fan0 to fan8). Up to 12 volt keys (from volt0 to volt11). Up to 9 gpu keys (from gpu0 to gpu8). IMPORTANT NOTE: Sometimes the output of lm_sensors shows the same exact names for different temperature values and so Moni- torix is unable to differentiate them. If you are under this situation please check the issue #131 (https://github.com/mikaku/Monitorix/issues/131) to solve this situation. desc This list complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the sensor. If no association is defined, then Mon- itorix will display the name of the key (left side) in the desc option (in uppercase in some graphs). <desc> mb0 = M/B fan0 = CPUFan gpu0 = ATI </desc> Please note that in the default graph all names are limited to 5 characters in order to fit up to 9 different values. In the zoomed graphs the limit is 8 characters. alerts This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the temperature or volts, or whatever that needs to be reached or exceeded within the specified time in time interval to execute the external script. The script is the full path name of the script that will be exe- cuted by this alert. Each defined sensor has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the first temperature sensor: <alerts> core0 = 3600, 40, /path/to/script.sh </alerts> Such alert means that if the value of the sensor core0 reaches or exceeds 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the value of the sensor. cmd This is the command that will be used to gather statistics. This option may also be used to add new sensors values not covered by LM-Sensors by referencing an external script which executes the command sensors and others. Default value: sensors use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps option shows gaps only if all data points are nan instead of requiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n Generic sensors statistics (gensens.pm) This graph helps to monitor up to three (so far) different sensors: temperatures, CPU frequencies and battery status which, depending of your machine, they should appear in the /sys directory. list This is a list of an unlimited number of groups to define the sensors to monitor. Each group is numbered starting from 0, and each one can hold up to 9 different entries separated by comma which corresponds to the names of the sensors present in your computer that you want to monitor. This module is capable to identify the type of the group by searching the substrings temp, cpu, bat, pwr, fan, pct and byt, so it will put automatically the vertical label in the graph accordingly (Celsius or Fahren- heit, Hz, Charge, Watts, RPM, Percent (%) and bytes respec- tively). Of course, it cannot supports mixed sensors in a same group. For example, if you need to monitor more than 9 tempera- ture sensors just create a new group in list. An example would be: <list> 0 = temp0, temp1 1 = cpu0, cpu1, cpu2, cpu3 2 = bat0 </list> title In this option you must associate a title with the group number specified in list. This is the title that will appear as the name of the graph. Following the settings in the example above: <title> 0 = Temperatures 1 = CPU frequency 2 = Battery status </title> desc In this option you must associate the complete pathname of the file from where to get the value of each entry defined in the list option. Following the settings in the example above: <desc> temp0 = /sys/devices/virtual/thermal/ther- mal_zone0/temp temp1 = /sys/devices/virtual/thermal/ther- mal_zone1/temp cpu0 = /sys/devices/system/cpu/cpu0/cpufreq/scal- ing_cur_freq cpu1 = /sys/devices/system/cpu/cpu1/cpufreq/scal- ing_cur_freq cpu2 = /sys/devices/system/cpu/cpu2/cpufreq/scal- ing_cur_freq cpu3 = /sys/devices/system/cpu/cpu3/cpufreq/scal- ing_cur_freq bat0 = /sys/class/power_supply/BAT0/capacity </desc> unit With this option you can define the order of magnitude associ- ated to a specific value. The value collected will be divided by the value defined here. For instance, the temperature sensors tend to give the value in 1000ths of degrees Celsius, something like 28300, which will need to be divided by 1000 to get the real temperature of 28.3. In the case of CPU frequencies the values come in Mhz which means that they need to be converted to Hz by dividing them by 0.001. Since the battery value represents a percentage, it doesn't need any special calculation. Therefore you can define something like this: <unit> temp0 = 1000 temp1 = 1000 cpu0 = 0.001 cpu1 = 0.001 cpu2 = 0.001 cpu3 = 0.001 bat0 = 1 </unit> map With this option you can optionally rename any of the sensor names defined in the list option. Following the above example: <map> temp0 = Temperature Zone 0 temp1 = Temperature Zone 1 cpu0 = CPU0 frequency cpu1 = CPU1 frequency cpu2 = CPU2 frequency cpu3 = CPU3 frequency bat0 = Battery 0 </map> All names are limited to 20 characters. alerts This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has four fields separated by comma: the time interval, the threshold, the path to the script to be executed and when the alert must be trig- gered. the last field is optional. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the value (temperature, Hz or battery charge) that needs to be reached or exceeded within the specified time in time interval to execute the external script. It can be spec- ified as a unique value or as a range of two values separated by a dash. The script is the full path name of the script that will be exe- cuted by this alert. The when value specifies when the alert must be triggered (above or below) the threshold, being above the default value when it's not specified. This forth parameter is only relevant when the threshold value is not a range. Each defined sensor has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the first temperature sensor: <alerts> temp0 = 3600, 40, /path/to/script.sh, above temp1 = 3600, 10, /path/to/script.sh, below temp2 = 3600, 40-60, /path/to/script.sh </alerts> The first alert means that if the value of the sensor temp0 ex- ceeds above 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The second alert means that if the value of the sensor temp1 ex- ceeds below 10 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The third alert means that if the value of the sensor temp2 ex- ceeds either below 40 or above of 60 during at least one hour (3600 seconds) the script in /path/to/script.sh will be exe- cuted. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the value of the sensor. 4th - the direction or when that alert was triggered by (above or below). IPMI sensor statistics (ipmi.pm) This graph is able to monitor an unlimited number of IPMI sensors (tem- peratures, fans and voltages). list This is a comma-separated list that describes the groups of sen- sors in desc. Put one description for each group. For every group specified you need to specify its sensors in the desc op- tion. WARNING: Every time the number of entries in this option changes, Monitorix will resize the ipmi.rrd file accordingly, removing all historical data. An example would be: list = Temperatures, Fans, Voltages desc This is a list of sensors per group defined. <desc> 0 = CPU Temp, System Temp 1 = FAN 1 2 = Vcore, 3.3VCC, 12V, VDIMM, 5VCC, CPU VTT, VBAT, VSB, AVCC </desc> The maximum number of sensors allowed for each group is 9. units This is the type of sensor in each group. It's important to not mix different type of sensors in a same group. This value is in- formative only, it's mostly used as a title for the y-axis in the graphs and should match with the output of the ipmitool com- mand. map This list complements the desc option. It basically allows you to change the name that will appear in the graph, hiding the real name of the sensor. If no association is defined, then Mon- itorix will display the name specified in the desc option. Note, this only works in names that don't include whitespaces unless you use the whitespace_key_support option and replace white- spaces with underscores in the key. alerts This optional list enables the alert capabilities for this graph and complements with the desc option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the temperature that needs to be reached or ex- ceeded within the specified time in time interval to execute the external script. The script is the full path name of the script that will be exe- cuted by this alert. Each defined sensor has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the first temperature sensor: <alerts> CPU_Temp = 3600, 40, /path/to/script.sh </alerts> Notice that the spaces in the sensor's name must be con- verted to underscores, since a variable can hold spaces in its name. Such alert means that if the value of the sensor CPU_Temp reaches or exceeds 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the value of the sensor. whitespace_key_support This list complements the map option. It changes the handling of the key names. Without this option enabled you can't rename keys with whitespaces using the map option. When enabled, whitespaces in the map key will be replaced by underscores(_) and enables you to specify the key names this way. Default value: n graphs_per_row This is the number of graphs that will be put in a row. Default value: 2 use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n extra_args This option includes any extra argument to the ipmitool command executed by Monitorix, which is "ipmitool <extra_args> sdr". This is specially useful if you need to monitor a remote server. An example would be: extra_args = -H <remote_ip> -U root -P <password> Default value: none Ambient sensor statistics (ambsens.pm) This graph is able to monitor an unlimited number of ambient sensors (temperatures, humidity, barometer, etc.). list This is a comma-separated list that describes the type of sen- sors in desc. Put one description for each type. For every type specified you need to specify its sensors in the desc option. Each one most be referenced as a numeric value starting from zero in the desc option. There you will define all the sensors than come with that type of sensor. WARNING: Every time the number of entries in this option changes, Monitorix will resize the ambsens.rrd file accordingly, removing all historical data. An example would be: list = Ambient temperature, Humidity desc This is a list of sensors per type defined. The name is irrele- vant. <desc> 0 = at1, at2, at3 1 = h0 </desc> The maximum number of sensors allowed for each type is 9. units This is the class of sensor for each type. It's important to not mix different type of sensors in a same group. This value is in- formative only, it's mostly used as a title for the y-axis in the graphs. cmd This list complements the desc option. It basically allows you to associate a script or program (which may include arguments) that will be executed to retrieve the value for each sensor. map This list complements the desc option. It basically allows you to change the name that will appear in the graph, hiding the real name of the sensor. If no association is defined, then Mon- itorix will display the name specified in the desc option. Note, this only works in names that don't include whitespaces. alerts This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has four fields separated by comma: the time interval, the threshold, the path to the script to be executed and when the alert must be trig- gered. the last field is optional. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the value (temperature, etc.) that needs to be reached or exceeded within the specified time in time interval to execute the external script. It can be specified as a unique value or as a range of two values separated by a dash. The script is the full path name of the script that will be exe- cuted by this alert. The when value specifies when the alert must be triggered (above or below) the threshold, being above the default value when it's not specified. This forth parameter is only relevant when the threshold value is not a range. Each defined sensor has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the first temperature sensor: <alerts> temp0 = 3600, 40, /path/to/script.sh, above temp1 = 3600, 10, /path/to/script.sh, below temp2 = 3600, 40-60, /path/to/script.sh </alerts> The first alert means that if the value of the sensor temp0 ex- ceeds above 40 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The second alert means that if the value of the sensor temp1 ex- ceeds below 10 during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The third alert means that if the value of the sensor temp2 ei- ther exceeds below 40 or above of 60 during at least one hour (3600 seconds) the script in /path/to/script.sh will be exe- cuted. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the value of the sensor. 4th - the direction or when that alert was triggered by (above or below). graphs_per_row This is the number of graphs that will be put in a row. Default value: 2 scientific_notation This is an option to enable scientific notation for the current value in the legend. Default value: n show_average This is an option to show also average, minimum and maximum val- ues in the legend Default value: n AMD GPU temperatures and usage (amdgpu.pm) This graph is able to monitor an unlimited number of AMD GPUs as long as the driver provides a hwmon interface. Usually it is not guaranteed to always get the same hwmon path so it is advised to assign fixed links via udev rules. list This is a list of groups of GPUs that you want to monitor. Each group will become a graph and there may be an unlimited number of groups. You can define device names like amd-w6800. WARNING: Every time the number of groups in this option changes, Monitorix will resize the amdgpu.rrd file accordingly, removing all historical data. To collect the GPU temperatures and usage data the hwmon subsys- tem is used. It is recommended that you first check if the hwmon subsystem is able to provide data from the GPU(s) that you plan to monitor. For example check /sys/class/hwmon/hwmon1 for available sensors. You can add it to the group 0 like this: <list> 0 = amd-w6800, amd-rx6900 1 = amd-wx5100 </list> The maximum number of GPUs allowed per group is 8. sensors This list specifies the sensor locations in absolute paths. If a certain card does not have a specific sensor you leave the entry empty instead (/path/sensor_file1, , /path/sensor_file2). The order has to be: GPU busy percent, memory busy percent, GPU clock, memory clock, memory used, power consumption, power limit, fan pwm value, GPU temperature, junction temperature, memory temperature. Power consumption and limit will be shown in one plot. <sensors> amd-rx6900 = /dev/amd-rx6900/device/gpu_busy_per- cent, /dev/amd-rx6900/device/mem_busy_percent, /dev/amd- rx6900/freq1_input, /dev/amd-rx6900/freq2_input, /dev/amd-rx6900/device/mem_info_vram_used, /dev/amd- rx6900/power1_average, /dev/amd-rx6900/power1_cap, /dev/amd-rx6900/pwm1, /dev/amd-rx6900/temp1_input, /dev/amd-rx6900/temp2_input, /dev/amd-rx6900/temp3_input amd-wx5100 = /dev/amd-wx5100/device/gpu_busy_per- cent, /dev/amd-wx5100/device/mem_busy_percent, /dev/amd- wx5100/freq1_input, /dev/amd-wx5100/freq2_input, /dev/amd-wx5100/device/mem_info_vram_used, /dev/amd- wx5100/power1_average, /dev/amd-wx5100/power1_cap, /dev/amd-wx5100/pwm1, /dev/amd-wx5100/temp1_input, , </sensors> map This list complements the list option. It basically allows you to change the GPU name that will appear in the graph, hiding the real device name. If no association is defined, then Monitorix will display the name of the GPU device as it is. <map> amd-w6800 = W 6800 amd-rx6900 = RX 6900 </map> desc This list complements the list option. It basically allows you to include a title for every group of GPUs. The title will ap- pear in the title of the graph. <desc> 0 = Host 1 = Virtual </desc> coretemp_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the core temperature. It works as follows: If the core temperature of any of the specified GPU device names reaches or subceeds the coretemp_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in coretemp_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n coretemp_timeintvl Not used in this alert. Default value: 0 coretemp_threshold This is the value that needs to be reached or subceeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: 10 coretemp_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in coretemp_timeintvl. 2nd - the value currently defined in coretemp_threshold. 3rd - the current core temperature. Default value: /path/to/script.sh memorytemp_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the memory temperature. It works as follows: If the memory temperature of any of the specified GPU names reaches or exceeds the memorytemp_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in memorytemp_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n memorytemp_timeintvl Not used in this alert. Default value: 0 memorytemp_threshold This is the value that needs to be reached or exceeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: 90 memorytemp_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in memorytemp_timeintvl. 2nd - the value currently defined in memorytemp_threshold. 3rd - the current memory temperature. Default value: /path/to/script.sh accept_invalid_amdgpu During the init stage this graph verifies that every defined de- vice name does exist in the system. If not, then the graph dis- ables itself. This option changes this behaviour and permits to continue work- ing even if the device names defined doesn't exist. Keep in mind that you will continue seeing error messages in the logfile. Default value: n show_current_values Print current values in the legend of the small righthand plots. Default value: n use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n respect_power_state This option, when enabled via y, will respect the AMD GPU D3 power state. Monitorix won't wake up a GPU in D3 power state to check the sensors values but skip it. The power state sensor has to be specified via the ower_states option for each GPU that should be respected. Default value: n power_states This list complements the respect_power_state option. You can specify the power_state sensor for each GPU that should not be woken up if in D3. <power_states> amd-w6800 = /dev/hwmon-w6800/device/power_state amd-rx6900 = /dev/hwmon-rx6900/device/power_state </power_states> NVIDIA GPU temperatures and usage (nvidiagpu.pm) This graph is able to monitor an unlimited number of Nvidia GPUs via nvidia-smi. list This is a list of groups of GPUs that you want to monitor. Each group will become a graph and there may be an unlimited number of groups. WARNING: Every time the number of groups in this option changes, Monitorix will resize the nvidiagpu.rrd file accordingly, remov- ing all historical data. As identifier you can either use the GPU ID or the GPU UUID found via nvidia-smi --list-gpus. You can add it to the group 0 like this: <list> 0 = 0, GPU-531b3e21-2fa4-1254-1215-2361f2d345ef 1 = 2 </list> The maximum number of GPUs allowed per group is 8. map This list complements the list option. It basically allows you to change the GPU name that will appear in the graph, hiding the real device name. If no association is defined, then Monitorix will display the name of the GPU device as it is. <map> 0 = RTX 3090 GPU-531b3e21-2fa4-1254-1215-2361f2d345ef = RTX 3080 2 = RTX 3080 Ti </map> desc This list complements the list option. It basically allows you to include a title for every group of GPUs. The title will ap- pear in the title of the graph. <desc> 0 = Host 1 = Virtual </desc> coretemp_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the core temperature. It works as follows: If the core temperature of any of the specified GPU device names reaches or subceeds the coretemp_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in coretemp_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n coretemp_timeintvl Not used in this alert. Default value: 0 coretemp_threshold This is the value that needs to be reached or subceeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: 10 coretemp_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in coretemp_timeintvl. 2nd - the value currently defined in coretemp_threshold. 3rd - the current core temperature. Default value: /path/to/script.sh memorytemp_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the memory temperature. It works as follows: If the memory temperature of any of the specified GPU names reaches or exceeds the memorytemp_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in memorytemp_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n memorytemp_timeintvl Not used in this alert.

Default value: 90 memorytemp_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in memorytemp_timeintvl. 2nd - the value currently defined in memorytemp_threshold. 3rd - the current memory temperature. Default value: /path/to/script.sh show_current_values Print current values in the legend of the small righthand plots. Default value: n use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n NVIDIA temperatures and usage (nvidia.pm) This graph requires to have installed the official NVIDIA drivers. max This is the number of NVIDIA cards currently plugged in your system. The maximum allowed is 9. Default value: 1 Disk drive temperatures and health (disk.pm) This graph is able to monitor an unlimited number of disk drives. list This is a list of groups of disk drives that you want to moni- tor. Each group will become a graph and there may be an unlim- ited number of groups. You can define device names or paths to devices like /dev/disk/by-path/pci-0000:00:11.0-scsi-0:0:0:0. WARNING: Every time the number of groups in this option changes, Monitorix will resize the disk.rrd file accordingly, removing all historical data. To collect the disk drive temperatures and health the smartmon- tools or the hddtemp command are required. Depending on the disk model reading smart values will wake up the disk and reset the sleep timer. To avoid waking them up set respect_standby = y but they still won't got to sleep automatically. It is recommended that you first check if either smartctl(8) or hddtemp are able to collect data from the disk drive(s) that you plan to monitor. You may test this with the following command: # hddtemp /dev/sda /dev/sda: WDC WD1600AABS-00M1A0: 48C If you see good results as above, you can add it to the group 0 like this: <list> 0 = /dev/sda, /dev/disk/by- path/pci-0000:00:11.0-scsi-0:0:0:0 1 = /dev/sdc, /dev/sdd </list> The maximum number of disk device names allowed per group is 8. map This list complements the list option.

Default value: 1 realloc_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in realloc_timeintvl. 2nd - the value currently defined in realloc_threshold. 3rd - the current number of reallocated sectors. Default value: /path/to/script.sh pendsect_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the number of current pending sec- tors (or bad sectors) in disk. It works as follows: If the number of current pending sectors in any of the specified disk device names reaches the pendsect_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in pendsect_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script.

It will receive the following three parameters: 1st - the value currently defined in pendsect_timeintvl. 2nd - the value currently defined in pendsect_threshold. 3rd - the current number of pending sectors. Default value: /path/to/script.sh accept_invalid_disk During the init stage this graph verifies that every defined de- vice name does exist in the system. If not, then the graph dis- ables itself. This option changes this behavior and permits to continue work- ing even if the device names defined doesn't exist. Keep in mind that you will continue seeing error messages in the logfile. Default value: n respect_standby This option, when enabled via y, won't wake up disks if they are already in standby but also won't report new smart during standby. Default value: n use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n NVME drive temperatures and health (nvme.pm) This graph is able to monitor an unlimited number of nvme drives. list This is a list of groups of nvme drives that you want to moni- tor. Each group will become a graph and there may be an unlim- ited number of groups. You can define device names or paths to devices like /dev/nvme0. WARNING: Every time the number of groups in this option changes, Monitorix will resize the nvme.rrd file accordingly, removing all historical data. To collect the nvme drive temperatures and health the smartmon- tools command are required. It is recommended that you first check if smartctl(8) is able to collect data from the nvme drive(s) that you plan to monitor.

It works as follows: If the percentage of available spare space in any of the speci- fied nvme device names reaches or subceeds the avails- pare_threshold (the interval of time is not used here), Moni- torix will execute the external alert script defined in avails- pare_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n availspare_timeintvl Not used in this alert. Default value: 0 availspare_threshold This is the value that needs to be reached or subceeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: 10 availspare_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in availspare_timeintvl. 2nd - the value currently defined in availspare_threshold. 3rd - the current percentage number of available spare space. Default value: /path/to/script.sh percentused_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the the percentage of NVM subsys- tem life used based on the actual usage and the manufacturer's prediction of NVM life. It works as follows: If the life percentage used in any of the specified nvme device names reaches or exceeds the percentused_threshold (the interval of time is not used here), Monitorix will execute the external alert script defined in percentused_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n percentused_timeintvl Not used in this alert. Default value: 0 percentused_threshold This is the value that needs to be reached or exceeded to trig- ger the mechanism for a particular action, which in this case is the execution of an external alert script. Default value: 90 percentused_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in percentused_timeintvl. 2nd - the value currently defined in percentused_threshold. 3rd - the current number of life percentage used. Default value: /path/to/script.sh accept_invalid_nvme During the init stage this graph verifies that every defined de- vice name does exist in the system. If not, then the graph dis- ables itself. This option changes this behavior and permits to continue work- ing even if the device names defined doesn't exist. Keep in mind that you will continue seeing error messages in the logfile. Default value: n show_extended_plots Show additional plots for mean read and written bytes per sec- ond, total bytes read and written, media errors and unsafe shut- downs Default value: y show_current_values Print current values in the legend of the small righthand plots. Default value: n use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n Filesystem usage and I/O activity (fs.pm) This graph is able to monitor an unlimited number of filesystems. list This is a list of groups of mounted filesystems that you want to monitor. Each group will become a graph and there may be an un- limited number of groups. WARNING: Every time the number of groups in this option changes, Monitorix will resize the fs.rrd file accordingly, removing all historical data. Take special care to use the same name as appears in the output of the df(1) command (the swap device is a special case). An ex- ample would be: <list> 0 = /, swap, boot, home, /mnt/backup </list> The maximum number of filesystems allowed per group is 8. desc This list complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the mount point. If no association is defined, then Monitorix will display the name specified in the list option. <desc> / = Root FS /home = My Home /mnt/backup = Backups </desc> You can define as much entries as you want. devmap This optional list complements the list option. When Monitorix is started, and in order to be able to show I/O activity, it at- tempts to detect the mapping of devices specified in list, as defined in the df command output column "Mounted on". In the event that devices are not detected by Monitorix, the devmap op- tion shall be used to manually define them, according to the un- derlying OS: Linux (kernel > 2.4) <devmap> device must match a device listed in the "/proc/diskstats" file. Linux (kernel <= 2.4) <devmap> is not used, but because something is de- fined in <devmap>, Monitorix will extract "disk_io" lines from the "/proc/stat" file. FreeBSD <devmap> device recognized by the output of "io- stat -xI <dev>" command. OpenBSD and NetBSD <devmap> is not used, but because something is de- fined in <devmap>, Monitorix will use the output of "iostat -DI" command. Just an example: <devmap> /mnt/home = dm-1 /mnt/backup = cciss/c0d2p6 </devmap> You can define as much entries as you want. alerts This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the percentage of disk space used in the file system that needs to be reached or exceeded within the specified time in time interval to execute the external script. The script is the full path name of the script that will be exe- cuted by this alert. Each defined filesystem has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the root filesystem: <alerts> / = 3600, 98, /path/to/script.sh </alerts> Such alert means that if the percentage of disk space used in the root filesystem reaches or exceeds 98 (more than 98) during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the filesystem disk usage. use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n has_removable_devices This option, when enabled via y, solves the problem with those hotpluggable devices that were offline when Monitorix was started, and later when they went online Monitorix don't know their device names and do not appear in the I/O statistics graphs, unless you restart Monitorix. So, when this option is enabled Monitorix will re-check the devices on every update. Default value: n ZFS statistics (zfs.pm) This graph is able to monitor an unlimited number of pools. max_pools This is the maximum number of pools that you can define in list. There is no limit to the number of pools monitored, but keep in mind that every time this number changes, Monitorix will resize the zfs.rrd file accordingly, removing all historical data. Default value: 5 list This is a comma-separated list of pool names. The number of pool names defined here can't be greater than the number defined in max_pools. Directory usage statistics (du.pm) This graph is able to monitor the usage of an unlimited number of di- rectories. IMPORTANT NOTE: The du command makes intensive disk I/O access that might slow down the whole system. Moreover, continued executions of this command will affect the buffer cache mechanism and this will also increase the system response time. To reduce executions refresh_inter- val can be specified in seconds (Use 0 for default refresh interval). list This is a comma-separated list that describes the groups of di- rectories in desc. Put one description for each group. For every group specified you need to specify its directories in the desc option. WARNING: Every time the number of entries in this option changes, Monitorix will resize the du.rrd file accordingly, re- moving all historical data. An example would be: list = System, Users desc This is a list of directories per group defined. <desc> 0 = /var/spool/mail, /var/spool/mqueue, /etc, /var/ftp, /tmp 1 = /home/ace, /home/gene, /home/paul, /home/peter </desc> The maximum number of directories allowed for each group is 9. type This specifies the information that will be presented for each directory specified in each list. It accepts two possible val- ues: size for the directory size (which is the default op- tion). files for the number of files inside the directory. An example would be: <type> 0 = size 1 = files </type> dirmap This list complements the desc option. It basically allows you to change the name that will appear in the graph, hiding the real name of the directory. If no association is defined, then Monitorix will display the name specified in the desc option. graphs_per_row This is the number of graphs that will be put in a row. Default value: 2 extra_args This option includes any extra argument to the du command exe- cuted by Monitorix, which is "du -ks". This is specially useful if you want to skip directories on different file systems, in this case just define this option like this: extra_args = "-x" IMPORTANT NOTICE: Keep in mind that including certain flags like '-h' (which gives results in human readable format) could make Monitorix unable to interpret the results. refresh_interval Refresh interval in seconds. This is an option to reduce the ex- ecution of the du command and undesired side effects caused by this. Default value 0 means normal refresh with all other plots. Besides the default meaningful values are from 60 to 86400. Keep in mind that changing the refresh_interval is possible without loosing history but changing the interval to a smaller one will introduce gaps in the data at the transition point. Default value: 0 use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n Network traffic and usage (net.pm) max This is the maximum number of network interfaces that you can define in list. There is no limit, but keep in mind that every time this number changes, Monitorix will resize the net.rrd file accordingly, removing all historical data. Default value: 10 list This is a comma-separated list of network interfaces that you may want to monitor. An example would be: list = eth0, eth1 desc This is the option where each network interface specified in list is described. Each definition consists of three parameters separated by comma: the description of the interface and the rigid and limit values. Put one description for each interface listed. An example would be: <desc> eth0 = FastEthernet LAN, 0, 1000 eth1 = ADSL 10Mbs Internet, 0, 1000 </desc> gateway This is where the network interface that acts as the gateway for this server is defined. This is mainly used if you plan to moni- tor network traffic usage of your devices/networks using the traffacct graph below. Netstat statistics (netstat.pm) This graph shows the state of the all IPv4 and IPv6 network connec- tions. Only the command to be used can be set here, besides the limit and rigid values. cmd This is the command that will be used to gather statistics. There are two possible values: ss netstat Default value: ss Tinyproxy statistics (tinyproxy.pm) This graph is able to monitor an unlimited number of Tinyproxy instal- lations. list This is a comma-separated list of URLs of Tinyproxys. WARNING: Every time the number of entries in this option changes, Monitorix will resize the tinyproxy.rrd file accord- ingly, removing all historical data. Default value: http://your.proxy.com/ desc This list complements the list option, it defines the URL from where Monitorix must gather the statistics for each Tinyproxy defined. An example of this option would be: <desc> http://your.proxy.com = http://tinyproxy.stats </desc> show_url If set to y Monitorix will show the original URL of each Tinyproxy at the bottom of the graph. For security reasons you may want to hide this information. Default value: y Traffic Control statistics (tc.pm) This graph is able to monitor an unlimited number of network interfaces managed by the tc command. list This is a comma-separated list of network interfaces that you may want to monitor. An example would be: list = eth0, eth1 desc This is the option where you define the queue disciplines you want to monitor for each network interface specified in list. An example would be: <desc> eth0 = cbq 1, sfq 10, sfq 20, sfq 30, ingress ffff eth1 = htb 1, pfifo 20, pfifo 21, pfifo 22 </desc> The maximum number of qdiscs allowed is 9. map This option complements the desc option. It basically allows you to change the name of the qdiscs that will appear in the graphs. If no association is defined, then Monitorix will show the name as specified in the desc option. Since the qdisc names have the space character in their names, they can't be used as the key in the association, instead you must the use their position number (starting by 0) in the desc option. An example would be: <map> <eth0> 0 = Class Based Queueing 1 = Stochastic Fairness Queueing 10 </eth0> <eth1> 0 = Hierarchical Token Bucket </eth1> </map> Libvirt statistics (libvirt.pm) This graph is able to monitor an unlimited number of virtual machines managed by Libvirt. cmd This is the command that will be used to gather statistics from each virtual machine listed in list. Default value: virsh An example would be: cmd = virsh -r -c qemu:///session list This is a list of groups of virtual machines that you want to monitor. Each group will become a graph and there may be an un- limited number of groups. WARNING: Every time the number of groups in this option changes, Monitorix will resize the libvirt.rrd file accordingly, removing all historical data. An example would be: <list> 0 = centos6, winxp </list> The maximum number of virtual machines allowed per group is 8. desc This list complements the list option and is mandatory for every virtual machine listed. You must define the virtual block device and the MAC address of the virtual network device that you want to monitor for every virtual machine. Just like this: <desc> centos6 = CentOS 6, vda, 52:54:00:45:d0:e7 winxp = MS Windows XP, hda, 52:54:00:97:1c:e5 </desc> You might also define this list using sections for each virtual machine, this way you'll be able to define multiple disks and multiple network interfaces for each virtual machine. Just like this: <desc> <centos6> desc = "CentOS 6" disk = vda, vdb, vdc net = 52:54:00:45:d0:e7, 52:54:00:45:d0:e8 </centos6> </desc> To obtain all these values you might want to use the following commands: # virsh domblklist centos6 Target Source ------------------------------------------------ vda /home/jordi/kvm/centos6.img hdc - # virsh domiflist centos6 Interface Type Source Model MAC ------------------------------------------------------- vnet3 network default virtio 52:54:00:45:d0:e7 This option also allows you to change the name that will appear in the graph, hiding the real name of the virtual machine. If no association is defined, then Monitorix will display the name specified in the list option. Process statistics (process.pm) This graph is able to monitor an unlimited number of processes. This graph requires a Linux kernel version 2.6.20 at least to support process I/O accounting. Some systems with older kernels might also have been ported it though. list This is a list of groups of processes that you want to monitor. Each group will become a graph and there may be an unlimited number of groups. WARNING: Every time the number of groups in this option changes, Monitorix will resize the process.rrd file accordingly, removing all historical data. Monitorix uses the following command to find the processes listed in this option: # ps -eo pid,comm,command Therefore names in the process list can be either exactly to the process name as it appears in the comm columns, or just a sub- string of the process name that appears in the command column. An example of this option would be: <list> 0 = httpd, sshd, ntpd, mysqld, proftpd, clamd, imap, sendmail, named, bash </list> The maximum number of processes allowed per group is 10. desc This list complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the process. If no association is defined, then Monitorix will display the name specified in the list option. <desc> httpd = Apache imap = Dovecot named = Bind </desc> You can define as much entries as you want. time_unit This is the unit in which will appear the values in the uptime graph. Possible values are: minute, hour or day. It will default to day even if none is specified. System services demand (serv.pm) This graph is able to monitor an unlimited number of system services or any application that has a log file. list This is a list of groups of services that you plan to monitor. Each group will become a graph and there may be an unlimited number of groups. WARNING: Every time the number of groups in this option changes, Monitorix will resize the serv.rrd file accordingly, removing all historical data. An example of this option would be: <list> Default = SSH, FTP, TELNET, IMAP, Samba, Fax, CUPS, POP3, SMTP, Spam, Virus, Fail2ban </list> The maximum number of services allowed per group is 16. desc This list complements the list option. It basically allows you to define how Monitorix will monitor such service. You must use the same name of service that you defined in list followed by an equal sign and a number of values. The first value indicates if this will be a C (counter) or a G (gauge). Counters are perfect for values that accumulate on every sample (match lines in logfiles), Gauges are for values that can change on every new sample (disk usage, Samba users, etc). The second value indicates the logfile from where Monitorix will extract the information. It must be prefixed with file: to indicate that it's a file. If you need to use the output of a program instead, then you can prefix it with exec: and Monitorix will run this script and will use its output as if it was the logfile. The third value is the first regular expression that Monitorix will use to match lines. It's normally used as the date that ap- pears in the log file. The forth and last value is a group of regular expressions sepa- rated by a plus sign. You can prefix a regular expresion with i: in order to note that it must be insensitive case. You can create multiple definitions of the same service with different values, so you are able to combine similar services into one single metric. <desc> SSH = C, file:/var/log/secure, "^%b %e", "sshd\[.*\]: Accepted " Spam = C, file:/var/log/maillog, "^%b %e", "MailScanner.*Spam Checks:.*Found.*spam messages" + "amavis\[.* SPAM" Spam = C, file:/var/log/sa-update.log, "^%b %e", "spamd: identified spam" SMTP = C, file:/var/log/maillog, "^%b %e", i:"to=.*stat(us)?=sent" IMAP = C, file:/var/log/uwimap, "%b %d", " imapd\[.* Login user=" IMAP = C, file:/var/log/dovecot, "%b %d", " imap-lo- gin: .* Login: " Samba = G, exec:/usr/local/bin/samba.sh, "", "" POP3 = C, file:/var/log/uwimap, "%b %d", " ipop3d\[.* Login user=" POP3 = C, file:/var/log/dovecot, "%b %d", " pop3-lo- gin: .* Login: " </desc> You can define as much entries as you want. mode This option toggles the way the System Services Demand data is represented in the graph. There are two possible values: i for incremental style. l for load (peaks) style. Default value: i graphs_per_row This is the number of graphs that will be put in a row. Default value: 2 Mail statistics (mail.pm) This graph requires either MailScanner or amavisd-new mail scanners in order to account spam and virus emails. Spamassassin and Clamav an- tivirus are also used for spam and virus email accounting. mta This option specifies the MTA that Monitorix will use to collect mail statistics. The currently supported MTAs are: Sendmail Postfix Exim NOTE: the pflogsumm utility is required when using the Postfix MTA. Default value: sendmail greylist This option specifies the Greylisting implementation that Moni- torix will use to collect statistical information. The currently supported Greylisting software is: milter-greylist postgrey In the case of milter-greylist, Monitorix shows the same data that appears at the end of the file greylist.db. In the case of Postgrey, Monitorix reads the mail_log file and searches for a specific type of lines. Lines of type "ac- tion=greylist, reason=new" appear as Greylisted in the graph. Lines of type "action=greylist, reason=early-retry" appear as Delayed in the graph. Lines of type "action=pass, reason=triplet found" appear as Passed in the graph. And finally, lines of type "action=pass, reason=client whitelist" appear as Whitelisted in the graph. Default value: milter-greylist stats_rate This option only affects the Mail Statistics and the Greylisting graphs, and it specifies the rate in which the values are saved and shown. This option has two possible values: real per_second If it's set to its default value (real), it will show the mes- sages as in a 'per minute' rate. Since Monitorix collects data on every minute, this should be the preferred way to see the re- sults. In the other hand, and in order to keep backwards compatibility, if this option is missing in the configuration file, it will act as if it was set up as per_second, which means that the number of messages collected in each minute will be divided by 60. Default value: real delvd_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the number of delivered messages. It works as follows: If the number of delivered messages reaches the delvd_threshold value for the interval of time defined in delvd_timeintvl, Moni- torix will execute the external alert script defined in delvd_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n delvd_timeintvl This is the period of time (in seconds) that the threshold needs to be exceeded before the external alert script is executed. Default value: 60 delvd_threshold This is the value that needs to be reached or exceeded within the specified time period in delvd_timeintvl to trigger the mechanism for a particular action, which in this case is the ex- ecution of an external alert script. The value of this option is compared against the number of de- livered messages since the last delvd_timeintvl seconds. Default value: 100 delvd_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in delvd_timeintvl. 2nd - the value currently defined in delvd_threshold. 3rd - the number of delivered messages. Default value: /path/to/script.sh mqueued_enabled This section enables or disables one of the alert capabilities for this graph; the alert for the number of queued messages. It works as follows: If the number of queued messages reaches the mqueued_threshold value for the interval of time defined in mqueued_timeintvl, Monitorix will execute the external alert script defined in mqueued_script. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. Default value: n mqueued_timeintvl This is the period of time (in seconds) that the threshold needs to be exceeded before the external alert script is executed. Default value: 3600 mqueued_threshold This is the value that needs to be reached or exceeded within the specified time period in mqueued_timeintvl to trigger the mechanism for a particular action, which in this case is the ex- ecution of an external alert script. The value of this option is compared with the number of messages in the mail queue. Default value: 100 mqueued_script This is the full path name of the script that will be executed by this alert. It will receive the following three parameters: 1st - the value currently defined in mqueued_timeintvl. 2nd - the value currently defined in mqueued_threshold. 3rd - the number of messages in the mail queue. Default value: /path/to/script.sh Network port traffic (port.pm) This graph requires the iptables(8) command and optionally the ip6ta- bles(8) command on Linux systems and the ipfw command on *BSD systems. max This is the number of network ports that you want to monitor. There is no limit to the number of ports monitored, but keep in mind that every time this number changes, Monitorix will resize the port.rrd file accordingly, removing all historical data. Default value: 9 rule This is the rule number that Monitorix will use when using the ipfw command to manage network port activity on *BSD systems. Change it if you think it might conflict with any other rule number. Default value: 24000 list You may define here up to max network port numbers. If you need to monitor the same network port with TCP and UDP protocols, you can add your own suffix to the port number (e.g: 443t and 443u) in order to distinguish it from the double definition in the <desc> block. It also support port ranges (e.g: 49152:65534) to be able to monitor the traffic of a number of consecutive ports summarized on a unique graph. If you see a red color in the background of a network port graph, it means that there is not a daemon listening on that port. This can be useful to know if some service gone down unex- pectedly. Of course, this is only valid on a single port, not ranged ports. desc This is the option where each network port specified in list is described. Each port definition consists of six parameters sepa- rated by comma: - an small port description. - the network protocol (tcp or udp). - the connection type (in, out or in/out). - the rigid value. - the limit value. - the L optional option which specifies that this port should be listening and Monitorix will advice it, by changing the background color of the graph to red, if finds it down. This option has no effect on ranged ports. There is also support (Linux only) for IPv6 network ports activ- ity by using protocol names as tcp6 or udp6. An example would be: list = 25, 25ip6, 80, 53t, 53u, 49152:65534 <desc> 25 = SMTP, tcp, in/out, 0, 1000, L 25ip6 = SMTP, tcp6, in/out, 0, 1000, L 80 = HTTP, tcp, in, 0, 1000, L 53t = DNS, tcp, in, 0, 1000, L 53u = DNS, udp, in, 0, 1000, L 49152:65534 = FTP_PSV, tcp, in, 0, 1000 </desc> As you can see, you cannot use the same port number twice. In- stead, you must distinguish it with some suffix. Monitorix will automatically extract all the first numeric digits, and will use that value as the network port number. graphs_per_row This is the number of graphs that will be put in a row. Consider the interaction of this parameter with the max option in order to adjust the size and number of graphs in relation to your hor- izontal screen size. Default value: 3 size This is the size of the graphs of the ports. It currently ac- cepts up to 8 different size names: large, main, medium, medium2, small, mini, tiny, zoom and remote. You can check the resolution of each size in the configuration file, inside the list named graph_size. Default value: mini cmd This option is used only under Linux systems. It is intended to define the command (with or without its complete path) that will be used to test if the network port is down (not listening). Currently there are only two possible values: ss netstat Default value: ss Users using the system (user.pm) Only the limit and rigid values can be set here. FTP statistics (ftp.pm) This graph supports currently ProFTPD, vsftpd and Pure-FTPd log file formats. For best results with the ProFTPD server I recommend to add the follow- ing line in its configuration file: ExtendedLog /var/log/proftpd/access.log AUTH,DIRS,READ,WRITE For best results with the vsftpd server I recommend to setup the option xferlog_std_format to NO, and the option ftp_log to /var/log/vs- ftpd.log. Pure-FTPd users might want to consider using the system syslog logfile. server This option specifies the FTP server. The currently supported FTP servers are: ProFTPD vsftpd Pure-FTPd Default value: proftpd anon_user This option lists the different names (separated by comma) that can adopt the Anonymous user in the FTP server defined in server. Default value: anonymous, ftp Apache statistics (apache.pm) This graph requires that mod_status be loaded and ExtendedStatus option set to On in order to collect full status information of the Apache web server. This graph is able to monitor an unlimited number of local and remote Apache web servers. list This is a comma-separated list of URLs of the monitored Apache web servers. WARNING: Every time the number of entries in this option changes, Monitorix will resize the apache.rrd file accordingly, removing all historical data. Default value: http://localhost/server-status?auto alerts This optional list enables the alert capabilities for this graph and complements with the list option. Each alert has three fields separated by comma: the time interval, the threshold and the path to the script to be executed. The time interval is the period of time (in seconds) that the threshold needs to be exceeded before the external script is ex- ecuted. The threshold is the number of remaining free slots that needs to be reached or exceeded within the specified time in time in- terval to execute the external script. The script is the full path name of the script that will be exe- cuted by this alert. Each defined Apache has its own alert. The default Monitorix installation includes an example of a shell-script alert called monitorix-alert.sh which you can use as a base for your own script. The following is an example of an alert defined for the local Apache: <alerts> http://localhost/server-status?auto = 3600, 5, /path/to/script.sh </alerts> Such alert means that if the remaining free slots reaches or ex- ceeds 5 (less than 5) during at least one hour (3600 seconds) the script in /path/to/script.sh will be executed. The external script will receive the following arguments: 1st - the value defined as time interval. 2nd - the value defined as threshold. 3rd - the remaining free slots. Nginx statistics (nginx.pm) This graph may require adding some lines in the configuration file ng- inx.conf. Please see the README.nginx file to determine the exact steps needed to configure Nginx to get status information. This graph requires the iptables(8) command on Linux systems, and the ipfw command on *BSD systems. url This is the URL to be used to collect Nginx stats. Default value: http://localhost/nginx_status port This is the network port the Nginx web server is listening on. It will be used for traffic (with iptables), and for nginx_sta- tus if url is not specified. If port of nginx_status is differ- ent from port then specify it in the url (http://host:port/ng- inx_status) Default value: 80 rule This is the rule number that Monitorix will use when using the ipfw command to manage Nginx network activity on *BSD systems. Change it if you think it might conflict with any other rule number. Default value: 24100 cmd This is the command that will be used to test if the Nginx web server is down (not listening). There are two possible values: ss netstat Default value: ss Lighttpd statistics (lighttpd.pm) This graph requires that mod_status is loaded in order to collect sta- tus information from the Lighttpd web server. This graph is able to monitor an unlimited number of local and remote Lighttpd web servers. list This is a comma-separated list of URLs of the monitored Lighttpd web servers. WARNING: Every time the number of entries of this option changes, Monitorix will resize the lighttpd.rrd file accord- ingly, removing all historical data. Default value: http://localhost/server-status?auto MySQL statistics (mysql.pm) This graph requires that you create a password protected MySQL user that is NOT granted privileges on any DB. Example: mysql> CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; mysql> FLUSH PRIVILEGES; where user is the new user name and password is the password that will be used for that user. This graph is able to monitor an unlimited number of local and remote MySQL web servers. NOTE: It is strongly recommended that you restart the MySQL service in order to avoid high peaks that could prevent correct display of the first plotted data. conn_type This option toggles the way how Monitorix establishes the con- nection with the MySQL server. There are two possible values: host using the network (hostname and IP address). socket using a socket file. Default value: host list This is a comma-separated list of hostnames or path to sockets of MySQL servers. WARNING: Every time the number of entries of this option change Monitorix will resize the mysql.rrd file accordingly, removing all historical data. Default value: localhost desc This is the option where each entry specified in the list is de- scribed. Each definition consists of three parameters separated by comma: the port, the username and the password. An example using the host type would be: <desc> localhost = 3306, user, secret </desc> When using the socket type the network port is, of course, ir- relevant but its field is still mandatory. This means that you must respect the three comma-separated values. Some of the values shown in the graphs are the result of a cal- culation of two values from either SHOW [GLOBAL] STATUS or SHOW VARIABLES. The following is an explanation of them: Thread Cache Hit Rate (1 - (Threads_created / Connections)) * 100 When an application connects to a MySQL database, the database has to create a thread to manage the connection and the queries that will be sent in that connection. The database instructs the kernel to create a new thread, and the kernel allocates re- sources and creates the thread, then returns it to the MySQL service. When the connection is terminated by the application, MySQL tells the kernel to destroy the thread and free the re- sources. This create/destroy mechanism causes considerable over- head if the MySQL server has many new connections per second. If MySQL doesn't destroy the thread when the connection is ter- minated, but reuses it and assigns it to the next connection then this will decrease the kernel overhead. This is why a high Thread Cache Hit Rate improves MySQL performance and decreases the system's CPU usage. Setting the parameter thread_cache_size in the my.cnf file ac- cordingly will help to correctly balance between having a great thread cache and keeping MySQL memory consumption reasonable. Higher is better. Query Cache Hit Rate Qcache_hits / (Qcache_hits + Com_select) * 100 Higher should be considered better. A query cache size increase is recommended if the query cache usage is very close to 100% and the query cache hit rate is far from 100%. But sometimes a size increase will not lead to a bet- ter hit rate: this means that the increase was not needed and that the application do not run enough cacheable SELECT queries. This value should grow proportionally with the number of exe- cuted queries as long as the query cache is performing well. Please also have a look at the Query cache usage percentage to know if your query_cache configuration is appropriate. For more information please refer to http://www.databasejour- nal.com/features/mysql/article.php/3808841/Optimizing-the-MySQL- Query-Cache.htm Query Cache Usage (1 - (Qcache_free_memory / query_cache_size)) * 100 This value should be reasonably far from 100%, otherwise con- sider incrementing the query_cache_size parameter in my.cnf. Connections Usage (Max_used_connections / max_connections) * 100 This value should be reasonably far from 100%, otherwise con- sider incrementing the max_connections parameter in my.cnf. Key Buffer Usage (Key_blocks_used / (Key_blocks_used + Key_blocks_unused)) * 100 This value should be reasonably far from 100%, otherwise con- sider incrementing the key_buffer_size parameter in my.cnf. InnoDB Buffer Pool Usage (1 - (Innodb_buffer_pool_pages_free / Inn- odb_buffer_pool_pages_total)) * 100 This value should be reasonably far from 100%, otherwise con- sider incrementing the innodb_buffer_pool_size parameter in my.cnf. Temp. Tables To Disk (Created_temp_disk_tables / Created_temp_disk_tables + Cre- ated_temp_tables)) * 100 During operation, MySQL has to create some temporary tables (that can be explicit, so created by the web application, or im- plicit, so for example MySQL has to create one when he runs some "SELECT DISTINCT", "UNION" or "VIEW" queries). MySQL will prefer to save this tmp tables to memory, for a fast access. But if tmp_table_size gets saturated, he has to write them on the disk instead, making the access slower. Note that if you modify the value of tmp_table_size in the MySQL configuration file, you should also modify the value of max_heap_table_size as well, since both values should have the same value because MySQL uses the minimum of both, so raising one of them is useless. Therefore this value helps to know how many tmp tables go to the disk instead than to the memory. Keep in mind that some large queries, involving TEXT and BLOB columns, are directly written to the disk instead than to the memory, because they would be too big. So you probably will want to avoid having a high % of tmp tables written to the disk, but you will never reach 0% on a big site, and this is fine. Lower is better ... but 0% is not reachable and you should not try to reach it, usually. PostgreSQL statistics (pgsql.pm) This graph is able to monitor an unlimited number of PostgreSQL servers. list This is a comma-separated list of names of PostgreSQL servers. WARNING: Every time the number of entries in this option changes, Monitorix will resize the pgsql.rrd file accordingly, removing all historical data.

Default value: localhost Fail2ban statistics (fail2ban.pm) This graph is able to monitor an unlimited number of Fail2ban jails. list This is a comma-separated list that describes the groups of jails in desc. Put one description for each group. For every group specified you need to specify its description in the desc option. WARNING: Every time the number of entries in this option changes, Monitorix will resize the fail2ban.rrd file accord- ingly, removing all historical data. An example would be: list = Security, Overload / Abuse desc This is a list of jails per group defined in your Fail2ban con- figuration. <desc> 0 = [apache], [apache-mod-security], [apache-overflows], [courierauth], [ssh], [pam-generic], [php-url-fopen], [vsftpd] 1 = [apache-imdbphp], [apache-evasive], [apache-badbots], [apache-robots-txt], [communigate], [named-refused-udp], [named- refused-tcp], [trac-ticketspam] </desc> The maximum number of jails allowed for each group is 9. graphs_per_row This is the number of fail2ban graphs that will be put in a row. Default value: 2 graph_mode This option changes how the values are represented in the graph. It has two possible values: absolute which is the default, and rate. The former takes the values directly from the command fail2ban-client status <JAIL> and so the values in the graph will appear as absolute. The later option shows the values in a rating format per minute. Default value: absolute Icecast Streaming Media Server (icecast.pm) This graph is able to monitor an unlimited number of Icecast servers. list This is a list of URLs of Icecast server status pages. WARNING: Every time the number of entries in this option changes, Monitorix will resize the icecast.rrd file accordingly, removing all historical data. Default value: http://localhost:8000/status.xsl desc This is a comma-separated list of Mount Points configured for every URL specified in the list option. IMPORTANT: the Mount Points must be specified in the same order that appears in the Icecast Server Status page. <desc> http://localhost:8000/status.xsl = stream1, stream2, stream3 </desc> The maximum number of mountpoints allowed for each URL is 9. graph_mode This changes the layout of the listeners graph, the possible values are r for a real graph, or s for a stacked graph (every line or area is stacked on top of the previous element). Default value: r Raspberry Pi sensor statistics (raspberrypi.pm) For more information please refer to http://elinux.org/RPI_vcgencmd_us- age. cmd This is where the vcgencmd command is installed. Default value: /usr/bin/vcgencmd clocks This is a comma-separated list of clock types that will be rep- resented in the first graph. An example would be: clocks = arm, core, h264, isp, v3d, uart, emmc, pixel, hdmi The maximum number of clocks allowed is 9. volts This is a comma-separated list of voltage types that will be represented in the third graph. An example would be: volts = core, sdram_c, sdram_i, sdram_p The maximum number of clocks allowed is 6. Alternative PHP Cache statistics (phpapc.pm) This graph is able to monitor an unlimited number of PHP-APC installa- tions. list This is a comma-separated list of URLs of PHP-APC status pages.

Default value: localhost:6379 PHP-FPM statistics (phpfpm.pm) This graph is able to monitor an unlimited number of PHP-FPM pools. group This is a list of names (separated by comma) of the groups of pools that you want to monitor. The pools included in each group will be defined in the list option. You can define unlimited number of groups. WARNING: Every time the number of groups changes, Monitorix will resize the phpfpm.rrd file accordingly, removing all historical data. An example of this option would be: <group> 0 = First group of domains 1 = Second group of domains </group> list This is a list of pool names that you want to monitor for each group defined in group. An example of this option would be: <list> 0 = example1, example2, example3 1 = example10, example11 </list> The maximum number of pools allowed per group is 8. desc This list complements the list option, it defines where and how Monitorix must gather the statistics for each pool defined. An example of this option would be: <desc> example1 = http://www.example1.com/php_fpm_status example2 = http://www.example2.com/php_fpm_status example3 = http://www.example3.com/php_fpm_status example10 = http://www.example10.com/php_fpm_status example11 = http://www.example11.com/php_fpm_status </desc> map This list also complements the list option. It basically allows you to change the name that will appear in the graph, hiding the real name of the pool. If no association is defined, then Moni- torix will display the name specified in the list option. An example of this option would be: <map> example1 = DOMAIN4 example12 = DOMAIN55 </map> APC UPS statistics (apcupsd.pm) This graph is able to monitor an unlimited number of APC UPS (apcupsd) installations. cmd This is the command that will be used (with the values in list) to get the statistics. Default value: apcaccess list This is a comma-separated list of hostnames with the network port running apcupsd. WARNING: Every time the number of entries in this option changes, Monitorix will resize the apcupsd.rrd file accordingly, removing all historical data. Default value: localhost:3551 use_nan_for_missing_data This option, when enabled via y, shows nan values for missing data instead of 0. This is useful when 0 could be mistaken for valid data. Default value: n gap_on_all_nan This option, when enabled via y, combined with the show_gaps op- tion shows gaps only if all data points are nan instead of re- quiring only one to be nan for a gap. This can be useful if not all sensor data are required for normal operation. Default value: n skipscale_for_transfer_voltage This option, when enabled via y, ignores the transfer voltage graph when scaling the plot axis. Default value: n skipscale_for_shutdown_level This option, when enabled via y, ignores the shutdown level graph when scaling the plot axis.

Default value: n Wowza Media Server (wowza.pm) This graph is able to monitor an unlimited number of Wowza servers. list This is a comma-separated list of URLs of Wowza server status pages. Each URL can include the Basic Authentication in the form of http://username:password@localhost:8086/connectioncounts. WARNING: Every time the number of entries in this option changes, Monitorix will resize the wowza.rrd file accordingly, removing all historical data. Default value: http://localhost:8086/connectioncounts desc This is a comma-separated list of applications configured for every URL specified in the list option. <desc> http://localhost:8086/connectioncounts = channel1, chan- nel2, channel3 </desc> The maximum number of applications allowed for each URL is 8. Devices interrupt activity (int.pm) Only the limit and rigid values can be set here. Verlihub statistics (verlihub.pm) This graph monitors the Verlihub software for DC++ network. Monitoring the Internet traffic of your LAN (traffacct.pm) If your server acts as the gateway for a group of PCs, devices or even whole networks in your local LAN, you may want to know how much Inter- net traffic each one is generating. This graph requires the iptables(8) command on GNU/Linux systems, and the ipfw command on *BSD systems. The following are the options you will need to configure to accomplish all of this. enabled This option enables this feature. Default value: n max This is the number of LAN devices you want to monitor. There is no limit, but keep in mind that every time this number changes, Monitorix will resize the traffacct.rrd file, removing all his- torical data. Default value: 10 graphs_per_row If your horizontal screen resolution is pretty wide, you may want to increase the number of graphs that appear on each row. Default value: 2 list This is a comma-separated list of names of PCs, LAN devices or whole networks that you want to monitor. The only requirement is that all they must utilize this server as their gateway. If the names in this list are able to be resolved by a DNS query then you don't need to define the desc list (below) with corre- sponding IP addresses, unless you want monthly reports. An example would be: list = pc8, printer, pc9, scanner desc This is the list of IPv4 or IPv6 addresses with network masks and email addresses corresponding to the entries defined in the list. This option is only used when the those entries are not resolvable through a DNS query. An example would be: <desc> 0 = 192.168.1.101/32, ace@example.com 1 = 192.168.1.102/32, gene@example.com 2 = 192.168.1.103/32, paul@example.com 3 = 2607:6300:93:1::/64, peter@example.com </desc Monthly reports of Internet traffic (traffacct.pm) enabled If this option is set to y, Monitorix will send a report of all the monthly Internet activity of the defined devices in list to the specified email address on the first day of each month. Default value: n language Define here the language used in the monthly report. The current possible values are: ca, de, en, it, nl_NL, pl and zh_CN. Default value: en default_mail This is the default email address used to send the monthly re- ports. This option is only used if the second parameter in desc list is empty. Default value: root@localhost url_prefix This is the prefix of the same URL you use to connect to Moni- torix. This is needed in order to get the graphs of the same ma- chine. Default value: http://localhost:8080 smtp_hostname This is the hostname that will be used as a SMTP relay to de- liver the monthly report emails. Default value: localhost from_address This is the address that will be used as remittent for all the monthly report emails. Default value: noreply@example.com Monitoring remote servers (Multihost) The Multihost feature allows you to monitor an unlimited number of re- mote servers that already have Monitorix installed. Make sure that all servers (local and remote) have the same version of Monitorix, other- wise there would be some incompatibilities that would prevent showing correctly the graphs. enabled This option enables the Multihost feature. Default value: n footer_url If set to y Monitorix will show the original URL of each server at the bottom of the graph. Where security is important you may want to hide this information. Default value: y graphs_per_row If your horizontal screen resolution is pretty wide, you may want to increase the number of graphs that appear on each row. Default value: 2 default_option_when_all If the user has defined a considerable amount of remote servers and it selects the option "All" in the Hostname list and "All graphs" in the Graph list, the browser may hang for a while due to the huge amount of images to download remotely from different servers. This option prevents precisely that this happens accidentally by setting a default value in the Graph list. Of course, the user is able to change it to "All graphs" at any moment. The value of this option may be any of the ones that appear in the <graphs> section (near the end) of the monitorix.conf file. Default value: "System load" remotehost_list This is a comma-separated list with descriptive names of remote servers with Monitorix already installed and working that you plan to monitor from here. An example of this list would be: remotehost_list = server 1, server 2, server 3 remotehost_desc This is a numbered list that describes each of the names defined in the remotehost_list option and the remote values of base_url and base_cgi options. An example would be: <remotehost_desc> 0 = http://www.example.com,/monitorix,/monitorix-cgi 1 = http://10.0.0.1,/monitorix,/monitorix-cgi 2 = http://192.168.0.100:8080,/,/ </remotehost_desc> As you can see all these three entries use URLs to designate the location of each remote server. This means that each server most also have been enabled the HTTP built-in server, or have been installed a CGI capable web server like Apache. groups This enables the server grouping for those environments where there are too much servers to display at the same time. Hence, you can group them in order to show them separately. Default value: n remotegroup_list This is a list of groups of remote servers with Monitorix al- ready installed and working that you plan to monitor from here. An example of this list would be: remotegroup_list = My Group remotegroup_desc This is a numbered list that describes each of the names defined in the remotegroup_list option. An example would be: <remotegroup_desc> 0 = server2, server 3 </remotegroup_desc> Automatic email reports (emailreports) This allows to send automatically selected graphs to one or more email addresses. This could be specially useful for some system administra- tors who prefer receiving via email selected graphs instead of browsing to the remote servers every day. enabled This option enables this feature. Note that you still need to enable the same option for each time interval you want to acti- vate: daily, weekly, monthly, yearly. Default value: n url_prefix This is the prefix of the same URL you use to connect to Moni- torix. Such URL is needed in order to get the graphs of that ma- chine. This option supports sending the credentials in the standard HTTP "Authorization" header, just like this: http://username:password@localhost:8080 Default value: http://localhost:8080 smtp_hostname This is the hostname that will be used as a SMTP relay to de- liver the automatic email reports. method This option specifies the method of sending emails. The current valid options are smtp and relay. By default this option is not defined which is the same as if smtp option was defined. Default value: from_address This is the address that will be used as remittent for all the monthly report emails. Default value: noreply@example.com subject_prefix This is a string that will be prefixed in the Subject of all emails that will be sent. Default value: Monitorix: hour This is the hour (in 24h format) when the email reports will be sent. Default value: 0 minute This is the minute when the email reports will be sent. Default value: 0 daily weekly monthly yearly The email reports are sent based on the following schedule: daily reports will be sent every day at 00:00h. weekly reports will be sent the first Monday of each week. monthly reports will be sent the first day of each month. yearly reports will be sent the first day of each year. enabled This option enables each report individually. Default value: n graphs This is a comma-separated list of graph names you want to appear in the email report. The names are the same as their .rrd files. There is a list of them in the graph_name option in moni- torix.conf. Default value: system, fs to This is a comma-separated list of recipient email addresses. addendum_script This is the full path name of an external script that will be executed during the creation of the report, and its output will be appended to the mail. This is useful for system administra- tors that want to add extra system information to the reports. Default value: rigid and limit values rigid This value defines how the graph must be scaled. Its possible values are: 0 No rigid, the graph will be scaled automatically. Only the lower-limit value will be used if it's defined. 1 The graph will be scaled by default according the values in limit but without rigidness. 2 The graph will be forced to scale using the contents of limit as its upper-limit and lower-limit values. limit This is where you can enter the upper-limit and lower-limit val- ues (separated by a colon) for a graph. The lower-limit value is optional. Some examples would be: 100:0 which means 100 as the upper-limit value and 0 for the lower-limit value. This is commonly used for percentage values. 1000 which means 1000 as the upper-limit value and leaving un- defined the lower-limit value. This can also be written as 1000:.
