The variable binary must point to your copy of the dig program. If it is not installed on your system yet, you should install bind-utils >= 9.0.0. The Probe asks the given host n-times for it's name. Where n is the amount specified in the config File. VARIABLES Supported probe-specific variables: binary The location of your dig binary. Example value: /usr/bin/dig This setting is mandatory. 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 timeout How long a single 'ping' takes at maximum Example value: 15 Default value: 5 Supported target-specific variables: /^influx_.+/ 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 lookup Name of the host to look up in the dns. Example value: www.example.org 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 server Name of the dns server to use. Example value: ns1.someisp.net AUTHORS Igor Petrovski <pigor@myrealbox.com>, Carl Elkins <carl@celkins.org.uk>, Andre Stolze <stolze@uni-muenster.de>, Niko Tyni <ntyni@iki.fi>, Chris Poetzel<cpoetzel@anl.gov> 2.9.0 2025-04-18 Smokeping_probes_DNS(3)
