Calculate CPU Usage in asp.net

Question

Hi all..

How to calculate CPU Usage in asp.net ??

Eg - How to get the following in single sign on intranet application -

1. User Name  -> page name he visits -> time taken by CPU to redirect to that page -> activity done and CPU Time for each activity -> etc

2. CPU Time for Page Load, CPU time for each and every action in the website / portal ??

I do not want to use the System.Diagnostics.Stopwatch .. This gives the elapsed time.

This is not giving the CPU Time.

Please guide.
