SMOKEPING_EXAMPLES(5) SmokePing SMOKEPING_EXAMPLES(5) NAME smokeping_examples - Examples of Smokeping configuration OVERVIEW This document provides some examples of Smokeping configuration files. All the examples can be found in the "examples" directory in the Smokeping documentation. Note that the DNS names in the examples are non-functional. Details of the syntax and all the variables are found in smokeping_config and in the documentation of the corresponding probe, if applicable. This manual is automatically generated from the Smokeping source code, specifically the Smokeping::Examples module. DESCRIPTION Currently the examples differ only in the "Probes" and "Targets" sections. The other sections are taken from the "etc/config.sample" configuration template in the Smokeping distribution so that the example files are complete. If you would like to provide more examples, document the other sections or enhance the existing examples, please do so, preferably by sending the proposed changes to the smokeping-users mailing list. Example 1: config.simple Probe configuration *** Probes *** +FPing binary = /usr/bin/fping Probe explanation Here we have just one probe, fping, pinging four hosts. The fping probe is using the default parameters, some of them supplied from the Database section ("step" and "pings"), and some of them by the probe module. Target configuration *** Targets *** probe = FPing menu = Top title = Network Latency Grapher remark = Welcome to this SmokePing website. + mysite1 menu = Site 1 title = Hosts in Site 1 ++ myhost1 host = myhost1.mysite1.example ++ myhost2 host = myhost2.mysite1.example + mysite2 menu = Site 2 title = Hosts in Site 2 ++ myhost3 host = myhost3.mysite2.example ++ myhost4 host = myhost4.mysite2.example Target explanation The hosts are located in two sites of two hosts each, and the configuration has been divided to site sections ('+') and host subsections ('++') accordingly. Example 2: config.multiple-probes Probe configuration *** Probes *** + FPing binary = /usr/bin/fping packetsize = 1000 + DNS binary = /usr/bin/dig lookup = name.example pings = 5 step = 180 + EchoPingHttp pings = 5 url = /test-url Probe explanation Here we have three probes: FPing for the regular ICMP pings, DNS for name server latency measurement and EchoPingHttp for web servers. The FPing probe runs with the default parameters, except that the ICMP packet size is 1000 bytes instead of the default 56 bytes. The DNS and EchoPingHttp probes have been configured to be a bit more gentle with the servers, as they only do 5 queries (pings) instead of the default 20 (or whatever is specified in the Database section). However, DNS queries are made more often: 5 queries every 3 minutes instead of every 5 minutes. Target configuration *** Targets *** probe = FPing menu = Top title = Network Latency Grapher remark = Welcome to this SmokePing website. + network menu = Net latency title = Network latency (ICMP pings) ++ myhost1 host = myhost1.example ++ myhost2 host = myhost2.example + services menu = Service latency title = Service latency (DNS, HTTP) ++ DNS probe = DNS menu = DNS latency title = Service latency (DNS) +++ dns1 host = dns1.example +++ dns2 host = dns2.example ++ HTTP menu = HTTP latency title = Service latency (HTTP) +++ www1 host = www1.example +++ www2 host = www2.example Target explanation The target tree has been divided by the probe used. This does not have to be the case: every target (sub)section can use a different probe, and the same probe can be used in different parts of the config tree. Example 3: config.fping-instances Probe configuration *** Probes *** + FPing binary = /usr/bin/fping ++ FPingNormal offset = 0% ++ FPingLarge packetsize = 5000 offset = 50% Probe explanation This example demonstrates the concept of probe instances. The FPingLarge and FPingNormal probes are independent of each other, they just use the same module, FPing. FPingNormal uses the default parameters, and so does FPingLarge except for the 5 kilobyte packetsize. Both use the same fping binary, and its path is configured FPing top section. The 'offset' parameters make sure the probes don't run at the same time - FPingNormal is run every 'full' 5 minutes (eg. 8:00, 8:05, 8:10 and so on, in wallclock time) while FPingLarge is run halfway through these intervals (eg. 8:02:30, 8:07:30 etc.) The top FPing section does not define a probe in itself because it has subsections. If we really wanted to have one probe named "FPing", we could do so by making a subsection by that name. Target configuration *** Targets *** probe = FPingNormal menu = Top title = Network Latency Grapher remark = Welcome to this SmokePing website. + network menu = Net latency title = Network latency (ICMP pings) ++ myhost1 menu = myhost1 title = ICMP latency for myhost1 +++ normal title = Normal packetsize (56 bytes) probe = FPingNormal host = myhost1.example +++ large title = Large packetsize (5000 bytes) probe = FPingLarge host = myhost1.example ++ myhost2 menu = myhost2 title = ICMP latency for myhost2 +++ normal title = Normal packetsize (56 bytes) probe = FPingNormal host = myhost2.example +++ large title = Large packetsize (5000 bytes) probe = FPingLarge host = myhost2.example Target explanation The target section shows two host, myhost1.example and myhost2.example, being pinged with two differently sized ICMP packets. This time the tree is divided by the target host rather than the probe. Example 4: config.targetvars-with-Curl Probe configuration *** Probes *** + Curl # probe-specific variables binary = /usr/bin/curl step = 60 # a default for this target-specific variable urlformat = http://%host%/ Probe explanation This example explains the difference between probe- and target- specific variables. We use the Curl probe for this. Every probe supports at least some probe-specific variables. The values of these variables are common to all the targets of the probe, and they can only be configured in the Probes section. In this case, the probe-specific variables are "binary" and "step". Target-specific variables are supported by most probes, the most notable exception being the FPing probe and its derivatives. Target-specific variables can have different values for different targets. They can be configured in both Probes and Targets sections. The values assigned in the Probes section function become default values that can be overridden in the Targets section. The documentation of each probe states which of its variables are probe-specific and which are target-specific. In this case the "urlformat" variable is a target-specific one. It is also quite uncommon, because it can contain a placeholder for the "host" variable in the Targets section. This is not a general feature, its usage is only limited to the "urlformat" variable and the "%host%" escape. (The reason why the FPing probe does not support target-specific variables is simply the fact that the fping program measures all its targets in one go, so they all have the same parameters. The other probes ping their targets one at a time.) Target configuration *** Targets *** probe = Curl menu = Top title = Network Latency Grapher remark = Welcome to this SmokePing website. + HTTP menu = http title = HTTP latency ++ myhost1 menu = myhost1 title = HTTP latency for myhost1 host = myhost1.example ++ myhost2 menu = myhost2 title = HTTP latency for myhost2 host = myhost2.example ++ myhost3 menu = myhost3 title = HTTP latency for myhost3 (port 8080!) host = myhost3.example urlformat = http://%host%:8080/ + FTP menu = ftp title = FTP latency urlformat = ftp://%host%/ ++ myhost1 menu = myhost1 title = FTP latency for myhost1 host = myhost1.example ++ myhost2 menu = myhost2 title = FTP latency for myhost2 host = myhost2.example Target explanation The target tree is divided into an HTTP branch and an FTP one. The servers "myhost1.example" and "myhost2.example" are probed in both. The third server, "myhost3.example", only has an HTTP server, and it's in a non-standard port (8080). The "urlformat" variable is specified for the whole FTP branch as "ftp://%host%/". For the HTTP branch, the default from the Probes section is used, except for myhost3, which overrides it to tag the port number into the URL. The myhost3 assignment could just as well have included the hostname verbatim (ie. urlformat = http://myhost3.example:8080/) instead of using the %host% placeholder, but the host variable would still have been required (even though it wouldn't have been used for anything). Example 5: config.echoping Probe configuration *** Probes *** + FPing binary = /usr/bin/fping # these expect to find echoping in /usr/bin # if not, you'll have to specify the location separately for each probe # + EchoPing # uses TCP or UDP echo (port 7) # + EchoPingDiscard # uses TCP or UDP discard (port 9) # + EchoPingChargen # uses TCP chargen (port 19) + EchoPingSmtp # SMTP (25/tcp) for mail servers + EchoPingHttps # HTTPS (443/tcp) for web servers + EchoPingHttp # HTTP (80/tcp) for web servers and caches + EchoPingIcp # ICP (3130/udp) for caches # these need at least echoping 6 with the corresponding plugins + EchoPingDNS # DNS (53/udp or tcp) servers + EchoPingLDAP # LDAP (389/tcp) servers + EchoPingWhois # Whois (43/tcp) servers Probe explanation This example shows most of the echoping-derived probes in action. Target configuration *** Targets *** # default probe probe = FPing menu = Top title = Network Latency Grapher remark = Welcome to this SmokePing website. + MyServers menu = My Servers title = My Servers ++ www-server menu = www-server title = Web Server (www-server) / ICMP # probe = FPing propagated from top host = www-server.example +++ http menu = http title = Web Server (www-server) / HTTP probe = EchoPingHttp host = www-server.example # default url is / +++ https menu = https title = Web Server (www-server) / HTTPS probe = EchoPingHttps host = www-server.example ++ cache menu = www-cache title = Web Cache (www-cache) / ICMP host = www-cache.example +++ http menu = http title = www-cache / HTTP probe = EchoPingHttp host = www-cache.example port = 8080 # use the squid port url = http://www.somehost.example/ +++ icp menu = icp title = www-cache / ICP probe = EchoPingIcp host = www-cache.example url = http://www.somehost.example/ ++ mail menu = mail-server title = Mail Server (mail-server) / ICMP host = mail-server.example +++ smtp menu = mail-server / SMTP title = Mail Server (mail-server) / SMTP probe = EchoPingSmtp host = mail-server.example ++ ldap-server menu = ldap-server title = ldap-server / ICMP host = ldap-server.example +++ ldap menu = ldap-server / LDAP title = LDAP Server (ldap-server) / LDAP probe = EchoPingLDAP ldap_request = (objectclass=*) host = ldap-server.example ++ name-server menu = name-server title = name-server / ICMP host = name-server.example +++ DNS menu = name-server / DNS title = DNS Server (name-server) / DNS probe = EchoPingDNS dns_request = name.example host = name-server.example ++ whois-server menu = whois-server title = whois-server / ICMP host = whois-server.example +++ Whois menu = whois-server / Whois title = Whois Server (whois-server) / Whois probe = EchoPingWhois whois_request = domain.example host = whois-server.example Target explanation All the servers are pinged both with ICMP (the FPing probe) and their respective echoping probe. The proxy server, www-cache, is probed with both HTTP requests and ICP requests for the same URL. Example 6: config.template Probe configuration *** Probes *** + FPing binary = /usr/sbin/fping *** Slaves *** secrets=/usr/local/etc/smokeping_secrets.dist +boomer display_name=boomer color=0000ff +slave2 display_name=another color=00ff00 Probe explanation This is the template configuration file distributed with Smokeping.
