Configuring the Memory Usage Alarm Threshold

Configuring the Memory Usage Alarm Threshold


Memory usage is an important indicator used to evaluate device performance. A high memory usage will cause service faults. During data processing, if the device can generate an alarm when high memory usage occurs, you can effectively monitor memory usage and optimize system performance to ensure system stability. To implement this function, you can set two thresholds:

  • Memory usage alarm threshold

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

  • Memory usage alarm recovery threshold

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


  1. (Optional) Run display memory threshold [ slot slot-id ]

    The memory usage configuration is displayed.

  2. Run system-view

    The system view is displayed.

  3. Run set memory threshold threshold-value [ restore restore-threshold-value ] [ slot slot-id ]

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

    By default, the memory usage alarm threshold is 95% and the memory usage alarm recovery threshold is 75%.

  4. Run commit

    The configuration is committed.
