Identifying CPU Suckers?!

My server's load goes high so often these days. It is Apache (httpd) that is responsible for these peaks. So, can I know:

1) which site causing these high loads, and
2) what visitors are accessing on that site to drive the high so high

Thank you in advance.

PS: cPanel is used in here Identifying CPU Suckers?!
