Module Description

NRPE (Nagios Remote Plugin Executor) allows you to remotely execute Nagios plugins on other Linux/Unix machines. This allows you to monitor remote machine metrics (disk usage, CPU load, etc.). This puppet module manages the installation and configuration of NRPE. It can install NRPE plugins and setup NRPE commands. Secure communication to NRPE using SSL is also supported.

Setup

The nrpe class installs the packages and configures the daemon. By default, it will only configure the daemon to listen on localhost. To allow connections from your nagios server, specify the allowed_hosts parameter when declaring the class.

class { 'nrpe':
  allowed_hosts => ['127.0.0.1', 'nagios.example.org'],
}

Usage

nrpe

No NRPE commands are configured by default. To make the configuration useful, at a minimum, declare some nrpe::command resources. To purge unmanaged NRPE commands:

class { 'nrpe':
  allowed_hosts => ['127.0.0.1'],
  purge         => true,
  recurse       => true,
}

Full documentation for the nrpe class is available in the reference documentation.

nrpe::command

This define can be used to add NRPE commands to the include directory for NRPE.

nrpe::command { 'check_users':
  ensure  => present,
  command => 'check_users -w 5 -c 10',
}

It is also possible to use hiera data to create these resources by using the base class commands parameter.

nrpe::commands:
  check_users:
    ensure: present
    command: 'check_users -w 5 -c 10'

Full documentation for the nrpe::command type is available in the reference documentation.

nrpe::plugin

This define can be used to install NRPE plugins.

nrpe::plugin { 'check_mem':
  ensure => present,
  source => 'puppet:///files/check_mem',
}

It is also possible to use hiera data to create these resources by using the base class plugins parameter.

nrpe::plugins:
  check_users:
    ensure: present
    source: 'puppet:///files/check_mem'

Full documentation for the nrpe::plugin type is available in the reference documentation.
