Nagios NRPE Server Configuration

This is an Ansible role that helps install and set up the Nagios NRPE Daemon.

I have chosen specific systems that I know work perfectly, but it should be compatible with any system where NRPE can be installed.

Currently, it supports:

Debian:
- Squeeze
- Wheezy
Ubuntu:
- Raring
- Saucy
- Trusty
RedHat:
- Version 6 and above
Arch Linux:
- All versions
Solaris:
- Version 11.1 and above

Requirements

For RedHat-based OS, you must have the EPEL repository enabled.

Role Information

This role allows you to deploy plugins globally or for specific servers. You can place plugins in files/plugins/global or create a directory in files/plugins/ with the server's Fully Qualified Domain Name (FQDN).

You can find your server's FQDN by using the Ansible Setup module.

Role Variables

Here are some important 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 settings are specific to the operating system and usually should not be altered.
