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 acquisition 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:
/ˆinflux_.+/

This is a tag that will be sent to influxdb and has no impact on the probe measurement. The tag name will be sent without the "influx_" prefix, which will be replaced with "tag_" instead. Tags can be used for filtering.

Example value: influx_location = In the basement

dns_request

The DNS request (domain name) to be queried.

Example value: example.org

This setting is mandatory.

dns_tcp

The echoping_dns ’--tcp’ option: use only TCP (’virtual circuit’). Enabled if specified with a value other than ’no’ or ’0’.

Example value: yes

dns_type

The echoping_dns ’-t’ option: type of data requested (NS, A, SOA etc.)

Example value: AAAA

Default value: A

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

plugin

The echoping plugin that will be used. See echoping (1) for details. This can either be the name of the plugin or a full path to the plugin shared object.

Example value: /path/to/dns.so

Default value: dns

pluginargs

Any extra arguments needed by the echoping plugin specified with the pluginname variable. These are generally provided by the subclass probe.

Example value: -p plugin_specific_arg

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

waittime

The "-w" echoping (1) option.

Example value: 1
