display cpu-monitor information

Function

The display cpu-monitor information command displays the CPU overload status of boards, CPU usage when the overload occurs, and callstack information about the three threads that consume the most CPU resources.

Format

display cpu-monitor information { slot slot-id | all }

Parameters

Parameter	Description	Value
slot slot-id	Specifies the slot ID of a board whose CPU overloading status is displayed.	-
all	Displays the CPU overloading status of all boards.	-

Parameter

Description

Usage Guidelines

When CPU usage is high, run this command to check whether the CPU is overloaded, CPU usage when the overload occurs, and callstack information about the three threads that consume the most CPU resources. If the CPU is overloaded, the administrator can take action to reduce CPU usage and ensure that the device is running properly.

The display cpu-usage command can be used to display CPU usage.

In VS mode, this command is supported only by the admin VS.

Example

The actual command output varies according to the device. The command output here is only an example.
