Example: Verifying the Problem and Cause for High CPU Utilization
To determine if high CPU utilization is a problem, enter the show processes cpu sorted privileged EXEC
command. Note the underlined information in the first line of the output example.

<output truncated>
This example shows normal CPU utilization. The output shows that utilization for the last 5 seconds is 8%/0%,
which has this meaning:
•
The total CPU utilization is 8 percent, including both time running Cisco IOS processes and time spent
handling interrupts.
•
The time spent handling interrupts is zero percent.
