VARIABLES

Supported probe-specific variables:

The location of your echoping binary.

Default value: /usr/bin/echoping

Run this many concurrent processes at maximum

Example value: 5

Default value: 5

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%

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:

Any extra options specified here will be passed unmodified to echoping(1).

Example value: -some-letter-the-author-did-not-think-of

The "-f" echoping(1) option.

Example value: A

The IP protocol used. Possible values are "4" and "6". Passed to echoping(1) as the "-4" or "-6" options.

Example value: 4

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

The "-p" echoping(1) option.

Example value: 6

The "-s" echoping(1) option.

Example value: 510

The "-t" echoping(1) option.

Example value: 1

Default value: 5

The "-P" echoping(1) option.

Example value: 0xa0

The "-w" echoping(1) option.

Example value: 1
