It is a work in progress and is tested against version 3.* of Joomla.

How it works

• Change its mode chmod +x check_joomla
• Update nrpe config file
  • Find the command's section
  • Add the line command[check_joomla]=/usr/lib/nagios/plugins/check_joomla -p=<path_to_joomla>
  • Change the <path_to_joomla> to fit your needs
• Restart nrpe service (sudo service nagios-nrpe-server restart)
• Add the command to your service definition:

 check_command                   check_nrpe!check_joomla

Requirements

This plugin requires that:

• you have installed a PHP interpreter
• the shebang is correctly handled from your system
• the SimpleXML extension is loaded and available
• (probably) that SimpleXML is able to access the internet and retrieve the update instractions from joomla
