Cisco Systems 12000 series Shows total percentage of CPU utilization 0 to 100 percent, CF-838

show processes cpu

	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.
