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.

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.
