Distribution: official part of Check_MK

Supported Agents: Linux, AIX, Solaris

The MRPE is a simple and efficient way to use standard Nagios Plugins with the check_mk_agent and thus emulate NRPE to a certain degree. Its main usage is to allow a soft migration from NRPE to check_mk and to use third party Nagios plugins that are running locally on your target hosts.

This check type processes the MRPE section in the output of the agent. Since all levels and parameters are configured on the target host, no parameters are needed here. Please refer to the online documentation on how to configure the agent.

The current version of the mrpe check is now cluster-aware and works well as a clustered_service (see article about Check_MK cluster monitoring). If an MRPE check is found on more than one node, then the best status of the checks is being used. So if the check is critical on one of the nodes and OK on another then the status, output and performance data of the OK check is being used as the gross result of the check.

Item

The service description of the check as configured in mrpe.cfg on the target host.

Check parameters

None.

Performance data

All performance data is transparently transported via check_mk to Nagios. If you are using PNP4Nagios, you can set perfdata_format = "pnp" in your main.mk. This will let PNP4Nagios choose a template matching the original check command.

Note: from version 1.1.9i2 on "pnp" is the default setting. You can change it back by setting perfdata_format to "standard".

Inventory

All plugins configured in mrpe.cfg are automatically inventorized.

Configuration variables

Variable	Type	Description
perfdata_format	string	Set to "pnp" for adding the check command for PNP4Nagios. Set to "standard" for omitting template information and better comply with the Nagios standard.
