Displaying the CPU Usage

Displaying the CPU Usage

Context

CPU usage is an important indicator of device performance. High CPU usage can cause service faults, for example, Border Gateway Protocol (BGP) route flapping, frequent Virtual Router Redundancy Protocol (VRRP) switchovers, or even user login failures. You can use the following commands to view CPU usage statistics and configurations in real time and verify that the device is running stably.

You can view CPU usage configurations to check the CPU usage alarm threshold and CPU usage alarm recovery threshold.

  • When the CPU usage reaches the alarm threshold, the system generates a CPU usage alarm.

  • When the CPU usage falls below the recovery threshold, the system generates a clear alarm.

Procedure

  • Run the display cpu-usage [ slave | slot slot-id ] [ vcpu vcpu ] command to view CPU usage statistics.
  • Run the display cpu-usage history [ 1hour | 24hour | 72hour ] [ slave | slot slot-id ] command to view CPU usage statistics within a period.
  • Run the display cpu-usage configuration [ slave | slot slot-id ] command to view CPU usage configurations.
