Configuring the CPU Usage Alarm Threshold

Configuring the CPU Usage Alarm Threshold

Context

The CPU is the core of a device. When the system has a large number of routes, significant CPU resources are used. This degrades system performance and delays data processing or increases the packet loss rate. During data processing, if the device can generate an alarm when high CPU usage occurs, you can effectively monitor CPU usage and optimize system performance to ensure system stability.

  • CPU usage alarm threshold

    When CPU usage reaches this threshold, the system generates an alarm.

  • CPU usage alarm recovery threshold

    When CPU usage falls back below this threshold, the system clears the alarm.

Procedure

  1. (Optional) Run:

    display cpu-usage configuration [ slave | slot slot-id ] 

    The CPU usage configurations are displayed.

  2. Run:

    system-view

    The system view is displayed.

  3. Run:

    set cpu-usage threshold threshold-value [ restore restore-threshold-value ] [ slot slot-id ]

    The CPU usage alarm threshold and CPU usage alarm recovery threshold are set.

    By default, the CPU usage alarm threshold is 95% and the CPU usage alarm recovery threshold is 80%.
