Puppet Class: nagios::nrpe::config

Defined in:
manifests/nrpe/config.pp

Overview

Class: nagios::nrpe::config

This will perform the configuration of the nrpe so that it allows the server to connect to it. It will also add nrpe checks for servers. The defaults are probably sensible for a normal linux server.

Variables

server

This is the ip address for the nagios server, which will be added to the allowed host line in the nagios nrpe config. Required.

monitoring_environment

This is the environment that the check will be submitted for. This will set the default for all checks added to nodes. Required.

nagios_service

This is the generic service that this check will implement. This will set the default for all checks added to nodes. Required.

diskspace

Whether to add a nagios check for diskspace on every drive. Not required. Defaults to true.

inodes

Whether to add a nagios check for inodes on every drive. Not required. Defaults to true.

iostat

Whether to add a nagios check for disk speed on every drive. Not required. Defaults to true.

kernel_leak

Whether to add a nagios check for kernel_leaks. This is slightly situational and potentially not useful, but only is used on 32 bit systems anyway Not required. Defaults to true.

load

Whether to add a nagios check for system load. Not required. Defaults to true.

memory

Whether to add a nagios check for memory usage. Not required. Defaults to true.

ntp

Whether to add a nagios check for ntp sync. This will by default check the time difference with the nagios server itself. Not required. Defaults to true.

total_procs

Whether to add a nagios check for total processes. This is probably not useful. Not required. Defaults to true.

zombie_procs

Whether to add a nagios check for zombie processes. Not required. Defaults to true.

lowmemory

Whether to add a nagios check for lowmemory (which only applies to 32 bit systems). Kernel leak is similar, so generally that should be used instead. Not required. Defaults to true.
