Configuring the CPU Usage Alarm Threshold

Configuring the CPU Usage Alarm Threshold

Context

When the system has a large number of routes, many CPU resources will be used. This degrades system performance, results in the delay in processing data, or causes a high 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 within this threshold, the system generates a clear alarm.

Batch configuration using scripts on a third-party software may cause high CPU usage, preventing the system from processing regular services.

Procedure

  1. (Optional) Run:

    display cpu-usage configuration

    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 ]

    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 75%.

    If restore-threshold-value is not specified, the CPU usage alarm recovery threshold is calculated as follows:

    • When the CPU usage alarm threshold is lower than 60%, the default CPU usage alarm recovery threshold is 1% lower than the CPU usage alarm threshold.

    • When the CPU usage alarm threshold is higher than or equal to 60%, the default CPU usage alarm recovery threshold is 5% lower than the CPU usage alarm threshold.
