Unless you're on a Windows server there really isn't a way to measure your CPU usage by account/site -- since it all runs under 1 process. You can only measure the total CPU used.
That's not *exactly* true - there is a roundabout way of doing it if the host is running PHP SuExec (where PHP scripts are run as the user, not as the apache/httpd user) and some clever scripting. It might not be the cleanest solution, but it's workable for estimate figures (it's not going to be 100% accurate, but it's a start).

You are correct - but, then you can turn the CPU time number into a percentage via the total number of seconds in the time period that you want to measure (i.e. 1 month, etc.).
Hope this helps....
