CPU usage is an important indicator to evaluate device performance. A high CPU usage may 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 learn about 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.
