Configuration Guide - Device Management
By default, the CPU usage alarm threshold is 80% and the CPU usage alarm recovery threshold
is 75%.
l When the CPU usage alarm threshold is lower than 60%, the default CPU usage alarm

2.4 Configuring the Memory Usage Alarm Threshold

You can configure the memory usage alarm threshold to monitor memory usage.
Context
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.

recovery threshold is 1% lower than the CPU usage alarm threshold.
alarm recovery threshold is 5% lower than the CPU usage alarm threshold.
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.
memory usage threshold is 90%.
threshold is 95%.
