Inspecting Cpu Utilization - Cisco AS5350 - Universal Access Server Configuration Manual

Inspecting CPU Utilization

The sum of the used and free memory equals the total memory. Most of the show memory summary
command output has been removed for brevity.
Do not enter the show memory summary command with the terminal length 0 command enabled. If
Note
you do, many screens of output might interrupt your session.
Note To learn more about management information bases (MIBs), see the online references at
http://www.cisco.com/univercd/cc/td/doc/product/software/.
Select your Cisco IOS release and search under new feature documentation.
Inspecting CPU Utilization
Enter the show process cpu command and then the show process cpu history command to investigate
high CPU utilization. High utilization causes network performance problems. For example, knowing
when the router is running at over 50% utilization is critical. The router might start dropping packets if
an unexpected traffic burst comes through or if Open Shortest Path First (OSPF) is recalculated. Fast
switching can also be used to reduce CPU utilization.
Router# show process cpu
CPU utilization for five seconds: 0%/0%; one minute: 1%; five minutes: 1%
