Romeo
With the "vmstat" command you will show three kinds of CPU data:
-overall utilization (you can identify if the CPU's speed is the
bottleneck)
- load averages. (impression of overall system performance)
- per-process CPU consumption (you can identify specific process
that are hogging resources)
%man vmstat
Thanks

I have a single cpu, rhel es 3.0 u 5 system that shows excessive 'system

I think, but, am not sure that the httpd process is causing this. Can
anyone suggest a method to find out:
1) what process is causing the system utilization to go up
2) what system calls are being made overall and how many of each?
Any help or suggestions on this would be appreciated. This is a
production system, so rebooting or shutting down processes is not
desirable.
