Usage Guidelines
Usage Scenario
The system collects CPU usage statistics at a specified interval (usually 60s) and saves them in the historical record table. To check CPU usage statistics within a period, run the display cpu-usage history command, and the command output helps you determine whether the CPU is working properly.
In the display cpu-usage history command output, the x-coordinate indicates the specified period, and the y-coordinate indicates the CPU usage. In the command output, the time axis is displayed from far to near. The closer the time axis is to the vertical coordinate, the more updated the CPU usage data is.
Precautions
This command is supported only on the admin VS.
If CPU usage is constantly higher than the upper alarm threshold before the feature is deployed on a large scale, check the device to troubleshoot the fault.
Example
The actual command output varies according to the device. The command output here is only an example.
