The mpstat command

The mpstat command produces the following output:
 Linux 2.6.11-1.1369_FC4 (example.redhat.com) 02/07/2006 01:22:23 PM CPU %user %nice %system %iowait %irq %soft %idle intr/s 01:22:23 PM all 0.02 0.00 0.02 0.02 0.02 0.00 99.92 1011.86 
On multiprocessor systems, mpstat allows the utilization for each CPU to be displayed individually, making it possible to determine how effectively each CPU is being used.
