Hi Everybody
*Can anybody explain me how to get %user, %nice, %sys and %iowait (in the way iostat) from /proc/stat?
e.g. "cat /proc/stat" from SuSe Linux 2.6.13-15-default
cpu 36074 365 31552 298360 28847 971 144 0

*Is it possible to compute "CPU Utilization" as
CPU Utilization = %user + %sys ?
* What does %nice represent for?
*Is it possible to imply "%iowait" for "I/O utilization"?
If not how to measure and to get the value of "I/O utilization" for the whole system, which include mouse/storages (local and perepheral)/USB devices/CDRom/...?
Thank you very much for your help.
