For newbies to openvz it is fairly difficult to understand the meaning of the numbers in /proc/user_beancounters file. Calculating the values to something understandable for human brain everytime you look at these statistics is much work. I have written a perl script which reformats the output to human-readable values in kbyte and mbyte.

Just be sure you have Perl installed on your HN/VE, copy this script to somewhere on your machine, give it executable rights and start it. The output will be like this:

Here's a quick patch which adds on VE hostname lookups. It depends on vzlist being in the path but won't break if it isn't.

Quick (and dirty) patch to only display the information of one container (first argument of the script). Usage:

Here is another modified version vzcomits.pl with some caculation addons and consistency checks. Also every possible value will be stored stored in hashes which makes it easy to add some more calculations.
