show cpu-monitoring
show cpu-monitoring {process <name>} {slot <slotid>}
Description
Displays the CPU utilization history of one or more processes.
Command Syntax
Default
N/A.
Usage Guidelines
Viewing statistics on a regular basis allows you to see how well your network is performing. If you
keep simple daily records, you will see trends emerging and notice problems arising before they cause
major network faults. This way, statistics can help you get the best out of your network.
By default, CPU monitoring is enabled and occurs every 20 seconds. The default CPU threshold value is
60%.
This information may be useful for your technical support representative if you experience a problem.
Depending on the software version running on your switch or your switch model, additional or
different CPU and process information might be displayed.
Modular Switches Only.
If you issue the command without any parameters, the switch displays CPU
utilization history for all of the processes running on the MSMs installed in your system.
Reading the Output.
The
show cpu-monitoring
command is helpful for understanding the behavior of a
process over an extended period of time. The following information appears in a tabular format:
●
Card—The location (MSM A or MSM B) where the process is running on a modular switch.
●
Process—The name of the process.
●
Range of time (5 seconds, 10 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: physical memory or virtual memory.
name
Specifies the name of the process.
slotid
Specifies the slot number of the MSM module:
• A specifies the MSM installed in slot A.
• B specifies the MSM installed in slot B.
NOTE: This parameter is available only on modular switches.
