VARIABLES
Supported probe-specific variables:
binary
The location of your echoping binary.
Default value: /usr/bin/echoping
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
Supported target-specific variables:
extraopts
Any extra options specified here will be passed unmodified to echoping(1).
Example value: -some-letter-the-author-did-not-think-of
ipversion
The IP protocol used. Possible values are "4" and "6". Passed to echoping(1) as the "-4" or "-6" options.
Example value: 4
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
priority
The "-p" echoping(1) option.
Example value: 6
timeout
The "-t" echoping(1) option.
Example value: 1
Default value: 5
tos The "-P" echoping(1) option.
Example value: 0xa0
url The URL to be requested from the web cache.
Example value: http://www.example.org/
This setting is mandatory.
waittime
The "-w" echoping(1) option.
Example value: 1
