⁠4.2.7. Nagios Plugins

Nagios Plugins ⁠[9] allow us to monitor services on remote hosts.
Pacemaker is able to do remote monitoring with the plugins if they are present.
A common use case is to configure them as resources belonging to a resource container (usually a virtual machine), and the container will be restarted if any of them has failed. Another use is to configure them as ordinary resources to be used for monitoring hosts or services via the network.
The supported parameters are same as the long options of the plugin.

[9] The project has two independent forks, hosted at https://www.nagios-plugins.org/ and https://www.monitoring-plugins.org/. Output from both projects' plugins is similar, so plugins from either project can be used with pacemaker.
