puppet-nagios-nrpe

This module automates the installation/management of the NRPE agent for Nagios/Opsview.

Tested to work on 32-bit/64-bit:

• Amazon AWS Linux
• CentOS 6.x
• Ubuntu 12.04

Parameters

• allowed_hosts: required
• ensure: optional, default=running
• enable: optional, default=true
• service_check_command: optional, default={}, hash containing the custom command definitions e.g. { 'command_name' => '/path/to/it ARG' }

Usage

Basic:

class { 'nrpe':
  allowed_hosts => [ "192.168.56.9", "10.10.10.23", ],
}

Modify the behaviour of the NRPE service:

class { 'nrpe':
  allowed_hosts => [ "192.168.56.9", "10.10.10.23", ],
  ensure => running,
  enable => false,
}

If you want to add custom service check commands:

class { 'nrpe':
  allowed_hosts         => [ "192.168.56.9", "10.10.10.23", ],
  ensure                => running,
  enable                => false,
  service_check_command => { 
    'check_mem'  => '/usr/local/nagios/plugins/check_mem 40 60',
    'check_blah' => '/usr/local/nagios/plugins/check_blah arg1 arg2',
  },
}

This will create the following in /etc/nagios/nrpe.cfg:

command[check_mem]=/usr/local/nagios/plugins/check_mem 40 60
command[check_blah]=/usr/local/nagios/plugins/check_blah arg1 arg2

Default command definitions

Please note that this is intended to be used with Opsview so parameter passing was enabled (dont_blame_nrpe=1).

command[check_users]=<%= libpath %>/nagios/plugins/check_users $ARG1$
command[check_disk]=<%= libpath %>/nagios/plugins/check_disk $ARG1$
command[check_procs]=<%= libpath %>/nagios/plugins/check_procs $ARG1$
command[check_load]=<%= libpath %>/nagios/plugins/check_load $ARG1$
command[check_swap]=<%= libpath %>/nagios/plugins/check_swap $ARG1$
