Setting up Check Plugins

On its own Icinga 2 does not know how to check external services. The Nagios Plugins Project provides an extensive set of plugins which can be used by Icinga 2 to check whether services are working properly.

The recommended way of installing these standard plugins is to use your distribution's package manager. For your convenience here is a list of package names for some of the more popular operating systems/distributions:

OS/Distribution Package Name Installation Path
RHEL/CentOS (EPEL) nagios-plugins-all /usr/lib/nagios/plugins or /usr/lib64/nagios/plugins
Debian nagios-plugins /usr/lib/nagios/plugins
FreeBSD nagios-plugins /usr/local/libexec/nagios
OS X (MacPorts) nagios-plugins /opt/local/libexec

Depending on which directory your plugins are installed into you may need to update the plugindir macro in your Icinga 2 configuration. This macro is used by the service templates contained in the Icinga Template Library to determine where to find the plugin binaries.

Integrate Additonal Plugins

You may require a custom check plugin not provided by the official Nagios plugins. All existing Nagios or Icinga 1.x plugins found on public community websites will work with Icinga 2 as well.

Once you have downloaded the plugin copy them into the directory defined by the global IcingaMacro $plugindir$ and make sure that the user the Icinga daemon is running as can execute the the plugin binary. Plugins should provide the --help parameter providing details how they must get called in your command definition later on.

# cp check_snmp_int.pl /usr/local/icinga/libexec/
# chmod +x /usr/local/icinga/libexec/check_snmp_int.pl

# /usr/local/icinga/libexec/check_snmp_int.pl --help

Note

You may require additional libraries for scripts. Please consult the installation documentation and/or README for their installation requirements.
