Show processes command
From NetworkCommands
A command available on most Cisco platforms; used to display software process CPU and memory utilisation statistics.
Contents |
Usage Syntax
show processes [memory options | cpu options]
Common memory options include;
- memory pid number - display detailed memory utilisation information for the specified process ID number
- memory sorted - display memory utilisation information for all processes, sorted high to low based on current memory utilisation
Common cpu options include;
- cpu history - display cpu utilisation history graphs (per second for last minute, per minute for last hour and per hour for last 72hrs)
- cpu sorted - display cpu utilisation information for all processes, sorted high to low based on current cpu utilisation
Usage Examples
show processes memory sorted - display memory utilisation information for all processes, sorted high to low based on current memory utilisation
show processes history - display cpu utilisation history graphs (per second for last minute, per minute for last hour and per hour for last 72hrs)
show processes cpu - display standard cpu utilisation information with information on last 5 seconds, 1 minute and 5 minutes
show proc cpu sorted | e 0.00% 0.00% 0.00% - display standard cpu utilisation, sort and exclude processes that have not utilised the cpu in the last 5 minutes
Usage Notes
Be aware the simply using the command, particularly multiple times in succession, will itself increase the CPU utilisation and thus may give an inaccurate impression of actual CPU utilisation.
High CPU Utilisation
See the Troubleshooting, High CPU, Cisco article for troubleshooting advice if you note high CPU utilisation when using this command.
