munin-limits¶
DESCRIPTION¶
munin-limits is one of the processes regularly run from the munin-cron script.
It reads the current and the previous collected values for each plugin, and compares them to the plugin’s warning and critical values, if it has any.
If the limits are breached, for instance, if a value moves from “ok” to “warning”, or from “critical” to “ok”, it sends an event to any configured contacts.
A common configured contact is “nagios”, which can use events from munin-limits as a source of passive service check results.
OPTIONS¶
-
--config<file>¶ Use <file> as configuration file. [/etc/munin/munin.conf]
-
--contact<contact>¶ Limit contacts to those of <contact<gt>. Multiple –contact options may be supplied. [unset]
-
--host<host>¶ Limit hosts to those of <host<gt>. Multiple –host options may be supplied. [unset]
-
--service<service>¶ Limit services to those of <service>. Multiple –service options may be supplied. [unset]
-
--always-send<severity list>¶ Force sending of messages even if you normally wouldn’t.
The <severity list> can be a whitespace or comma separated list of the values “ok”, “warning”, “critical” or “unknown”.
This option may be specified several times, to add more values.
Use of “–always-send” overrides the “always_send” value in munin.conf for configured contacts. See also –force.
-
--force¶ Alias for “–always-send ok,warning,critical,unknown”
-
--force-run-as-root¶ munin-limits will normally prevent you from running as root. Use this option to override this.
The use of this option is not recommended. You may have to clean up file permissions in order for munin to run normally afterwards.
-
--help¶ View help message.
-
--debug¶ Log debug messages.
-
--screen¶ If set, log messages to STDERR on the screen.
