Smokeping_prob...PingContinuous(3) SmokePing Smokeping_prob...PingContinuous(3) NAME Smokeping::probes::FPingContinuous - FPingContinuous Probe for SmokePing SYNOPSIS *** Probes *** +FPingContinuous binary = /usr/bin/fping # mandatory hostinterval = 1.5 offset = 50% packetsize = 5000 pings = 20 sourceaddress = 192.168.0.1 step = 300 timeout = 1.5 tos = 0x20 usestdout = false # The following variables can be overridden in each target section /^influx_.+/ = influx_location = In the basement # [...] *** Targets *** probe = FPingContinuous # if this should be the default probe # [...] + mytarget # probe = FPingContinuous # if the default probe is something else host = my.host /^influx_.+/ = influx_location = In the basement DESCRIPTION Integrates FPingContinuous as a probe into smokeping. The variable binary must point to your copy of the FPing program. If it is not installed on your system yet, you can get a slightly enhanced version from "pub" in www.smokeping.org. The (optional) packetsize option lets you configure the packetsize for the pings sent. Continuous output is normally sent to stdout, but you can set usestdout to 'false' to make smokeping read stderr instead of stdout. The FPing manpage has the following to say on this topic: Number of bytes of ping data to send. The minimum size (normally 12) al- lows room for the data that fping needs to do its work (sequence number, timestamp). The reported received data size includes the IP header (nor- mally 20 bytes) and ICMP header (8 bytes), so the minimum total size is 40 bytes. Default is 56, as in ping. Maximum is the theoretical maximum IP datagram size (64K), though most systems limit this to a smaller, sys- tem-dependent number. VARIABLES Supported probe-specific variables: binary The location of your fping binary. Example value: /usr/bin/fping This setting is mandatory. hostinterval The fping "-p" parameter, but in (possibly fractional) seconds rather than milliseconds, for consistency with other Smokeping probes. From fping(1): This parameter sets the time that fping waits between successive pack- ets to an individual target. Example value: 1.5 offset If you run many probes concurrently you may want to prevent them from hitting your network all at the same time. Using the probe-specific offset parameter you can change the point in time when each probe will be run. Offset is specified in % of total interval, or alternatively as 'random', and the offset from the 'General' section is used if nothing is specified here. Note that this does NOT influence the rrds itself, it is just a matter of when data acquisition is initiated. (This vari- able is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) Example value: 50% packetsize The ping packet size (in the range of 12-64000 bytes). Example value: 5000 pings How many pings should be sent to each target, if different from the global value specified in the Database section. Note that the number of pings in the RRD files is fixed when they are originally generated, and if you change this parameter afterwards, you'll have to delete the old RRD files or somehow convert them. Example value: 20 sourceaddress The fping "-S" parameter . From fping(1): Set source address. Example value: 192.168.0.1 stepDuration of the base interval that this probe should use, if different from the one specified in the 'Database' section. Note that the step in the RRD files is fixed when they are originally generated, and if you change the step parameter afterwards, you'll have to delete the old RRD files or somehow convert them. (This variable is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) Example value: 300 timeout The fping "-t" parameter, but in (possibly fractional) seconds rather than milliseconds, for consistency with other Smokeping probes. Note that as Smokeping uses the fping 'counting' mode (-C), this apparently only affects the last ping. Example value: 1.5 tos Set the type of service (TOS) of outgoing ICMP packets. You need at laeast fping-2.4b2_to3-ipv6 for this to work. Find a copy on www.smokeping.org/pub. Example value: 0x20 usestdout Listen for FPing output on stdout instead of stderr ... (continuous output is normally sent to stdout).
