The CPU is the core of a device. When the system has a large number of routes, many CPU resources will be used. This degrades system performance and causes high packet loss or a delay in processing data. If high CPU usage occurs when processing data, the device can generate an alarm. This enables you to monitor CPU usage and optimize system performance.
CPU usage alarm threshold
When CPU usage reaches this threshold, the system generates an alarm.
CPU usage alarm recovery threshold
When CPU usage falls below this threshold, the system clears the alarm.
The CPU usage configurations are displayed.
The system view is displayed.
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%.
