Nagios NRPE Server Config

An Ansible role to handle the installation and rollout of the Nagios NRPE Daemon.

I've only selected certain platforms that I know this 100% works on, but it should work on any platform that NRPE can be installed on.

Currently supports:

• Debian
  • Squeeze
  • Wheezy
• Ubuntu
  • Raring
  • Saucy
  • Trusty
• RedHat
  • At least 6 onwards
• Arch Linux
  • All
• Solaris
  • At least 11.1

Requirements

RedHat based OS's must have the EPEL repo.

Role Information

This role gives you the ability to deploy plugins on a global and per-server basis. This can be done by putting plugins into files/plugins/global or by creating a folder in files/plugins/ that is the servers FQDN.

You can find out your servers FQDN by running the Ansible Setup module.

Role Variables

• nagios_nrpe_server_bind_address: 127.0.0.1
• nagios_nrpe_server_port: 5666
• nagios_nrpe_server_allowed_hosts: 127.0.0.1
• nagios_nrpe_command: see example playbook section
