====== Froxlor Panel Nagios/Icinga Plugin ======

This plugin helps to keep track of hanging Froxlor cron jobs. It works only with a modified froxlor_master_cronjob.php and cron_ini.php. (see [[http://redmine.froxlor.org/issues/841|here]] for a patch). The below listed script will also serve as the framework for any other checks that may be needed in the future.

Once you have the cronjobs running right use check_froxlor to keep an eye on things:
