script to monitorize counter errors

[muzzol]

hi,

i've been working on a zimbra-proxmox environment and i've created this simple script to check errors on /proc/user_beancounters

can be used in nagios or in any other monitoring system

feel free to add it to wiki or any other place.

#!/bin/bash

# script for checking system counters on a openvz container
# must be executed inside the container and is mainly focused
# on using it with nagios
#
# feel free to use it and modify it
