Displaying CPU Utilization History

Display the CPU utilization history of one or more processes using the command:
show cpu-monitoring {process name} {slot slotid}
Where the following is true:
- name—Specifies the name of the process.
- slot—On a SummitStack, specifies the slot number of the target node. The number is a value from one (1) to eight (8).
Output from this command includes the following information:
- Process—The name of the process.
- Range of time (five seconds, ten seconds, and so forth)—The CPU utilization history of the process or the system. The CPU utilization history goes back only 1 hour.
- Total User/System CPU Usage—The amount of time recorded in seconds that the process spends occupying CPU resources. The values are cumulative meaning that the values are displayed as long as the system is running. You can use this information for debugging purposes to see where the process spends the most amount of time: user context or system context.
Clear the utilization history stored in the switch and reset the statistics to zero using the command:
clear cpu-monitoring {process name} {slot slotid}

The following is sample truncated output from a switch:

X460G2-48p-G4.1 # show cpu-monitoring
