How to get CPU utilization?

Hi,

I need to do some overload control work based on status of CPU usage. The
server I used has more than one CPU, and operating system on it is solaris
5.7. As we know, the process information is stored in the psinfo under
/proc/<pid>. I wonder if I need to access each process CPU usage from psinfo
and then calculate CPU percent usage of the server, and how to get each CPU
usage?

Thanks very much!
