Checking CPU resources

To check the CPU resources:

1. During the busy hour or when alarms are being logged, type sar and press Enter.

   The system displays the CPU Resources screen. The sum of columns 2 and 3, (usr + sys) represents the percentage of CPU being used.

2. During the busy hour only, type sar -u 5 50 and press Enter.

   The system displays current CPU usage every 5 seconds for 50 seconds.

If either of these tests show CPU utilization consistently over 70 percent, it is likely that CPU overload is causing the performance problem.
