Nagios is an awesome monitoring-tool. I give my best to check as much services as possible with nagios. Here I want to explain how I check if updates for the Horde-Framework exist...

Although horde uses pear for update-management I don't want to check pear directly(because of permissions and of course I don't want to create too much traffic on the horde-repository) in my nagios-check. That's why i created a simple cronjob which checks pear and write it's output into file. This file is readable for the nagios-check..
