Perhaps it's worth adding that the output of that script corresponds
roughly to the output of the munin "cpu" plugin, and that I've also
written an OpenVZ-specific version which gives a breakdown by virtual
machine as well....  If you'd prefer the option of looking at graphs
instead, that might be worth checking them both out.  Screenshots follow:

and

The cpu plugin comes with munin (on debian, ubuntu etc. just "aptitude
install munin munin-node") - you have to manually download and install
the plugin which I wrote from the above link....

Cheers,

Tim.
