Nagios NRPE Server Configuration

This is an Ansible role for installing and setting up the Nagios NRPE Daemon.

I have only included certain platforms that I know work 100%, but it should function on any platform where NRPE can be installed.

Current Supported Platforms:

• Debian:
  • Squeeze
  • Wheezy
• Ubuntu:
  • Raring
  • Saucy
  • Trusty
• RedHat:
  • At least version 6 and above
• Arch Linux:
  • All versions
• Solaris:
  • At least version 11.1

Requirements

For RedHat-based operating systems, you need to have the EPEL repository.

Role Information

This role allows you to deploy plugins either globally or specifically for each server. Use the files/plugins/global folder for global plugins, or create a folder in files/plugins/ named with the server's Fully Qualified Domain Name (FQDN).

To find out your server's FQDN, run the Ansible Setup module here.

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

These variables are specific to the operating system and generally should not be changed.
