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.
Device# show processes cpu sorted

<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
• The time spent handling interrupts is zero percent.
