Puppet Class: nagios::nrpe::memory

Defined in:
manifests/nrpe/memory.pp

Overview

Class: nagios::nrpe::memory

Uses a simple check mem script from nagios exchange (could potentially do with cleaning up). Will warn if less than 15% memory, critical on 5%.

It will deploy the check, add the command and then create the service on the nagios server

Parameters

monitoring_environment

This is the environment that the check will be submitted for. This will default to the value set by nagios::nrpe::config but can be overridden here. Not required.

nagios_service

This is the generic service that this check will implement. This should be set by nagios::nrpe::config but can be overridden here. Not required.

nagios_alias

This is the hostname that the check will be submitted for. This should almost always be the hostname, but could be overriden, for instance when submitting a check for a virtual ip. Not required.
