check beancounters

OpenVZ containers may have limited resources, if they reach their maximum and try to request more of a single resource they produce a fail-count that is displayed in /proc/user_beancounters. Maybe you want to get notified about that problem, this script monitors the file and alerts if any fail-counter increases.
To reset the fail-counts you have to restart the container, but sometimes there isn’t the chance to reboot a virtual machine. So this script copies the /proc/user_beancounters (at default the copy is located at /tmp/user_beancounters) and alerts about diffs. To disable the alert just delete the copy, the script will create a new copy when it is called the next time. So there won’t be a diff anymore.

To get read access to /proc/user_beancounters for the user nagios don’t forget to set the s-bit (chmod +s check_UBC.pl).

Maybe you have to modify the location of your utils.pm by updating the lib-path in line 13
