linux - How can I measure precisely the resources consumed by each Web site on my server?

We are having performance issues on our server which may or may not be the inevitable result of high traffic to our sites. We would like to optimize each site for performance so that we can be sure we're getting the most "bang for our buck" before purchasing additional hardware.



I was wondering if anyone knew of some creative ways to measure the resources (memory, bandwidth, CPU time, etc) consumed by each Web site. This could allow us to spot the biggest "offenders" and start working on those first.



We are running Red Hat Enterprise Linux Server release 5.6 (Tikanga)
