show processes cpu
CF-838
Cisco IOS Configuration Fundamentals Command Reference
July 2008
Maximum usage is measured and recorded every second; average usage is calculated on periods of more
than one second. Consistently high CPU utilization over an extended period of time indicates a problem
and using the show processes cpu command is useful for troubleshooting. Also, you can use the output
of this command in the Cisco Output Interpreter tool to display potential issues and fixes. Output
Interpreter is available to registered users of Cisco.com who are logged in and have Java Script enabled.

Cisco IOS Software Modularity
Cisco IOS Software Modularity images display only one graph that shows the CPU utilization for the
last 60 minutes. The horizontal axis shows times (for example, 0, 5, 10, 15 minutes), and the vertical axis
shows total percentage of CPU utilization (0 to 100 percent).
Examples Example output varies between Cisco IOS software images and Cisco IOS Software Modularity software
images. To view the appropriate output, choose one of the following sections:

The following is sample output of the one-hour portion of the output. The Y-axis of the graph is the CPU
utilization. The X-axis of the graph is the increment within the time period displayed in the graph. This
example shows the individual minutes during the previous hour. The most recent measurement is on the
left of the X-axis.
