NAME

Smokeping::probes::SipSak - tests sip server

OVERVIEW

This probe sends OPTIONS messages to a sip server testing the latency.

SYNOPSIS

 # probe = SipSak # if the default probe is something else
 host = my.host

DESCRIPTION

The probe uses the sipsak <http://sipsak.org/> tool to measure sip server latency by sending an OPTIONS message.

The sipsak command supports a large number of additional parameters to fine-tune its operation. Use the params variable to configure them.

VARIABLES

Supported probe-specific variables:

binary

The location of your echoping binary.

Default value: /usr/bin/sipsak

forks

Run this many concurrent processes at maximum

Example value: 5

Default value: 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 acqusition is initiated. (This variable is only applicable if the variable 'concurrentprobes' is set in the 'General' section.)

Example value: 50%

step

Duration 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

How long a single 'ping' takes at maximum

Example value: 15

Default value: 5

Supported target-specific variables:

keep_second

If OPTIONS is actually implemented by the server, SipSak will receive two responses. If this option is set, the timeing from the second, final response will be counter

Example value: yes

params

additional sipsak options. The options will get split on space.

Example value: --numeric --password=mysecret

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: 5

port

usa non-default port for the sip connection.

Example value: 5061

sipsak_timeout

Timeout for sipsak in seconds (fractional)

Default value: 2

user

User to use for sip connection.

Example value: nobody
