check_joomla is a nagios's plugin to check joomla's version.
It is a work in progress and is tested against version 3.* of Joomla.
- Copy the check_joomla script in nagios's plugin folder (eg: /usr/lib/nagios/plugins/).
- 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
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
