Memory usage is an important indicator used to evaluate device performance. A high memory usage may cause service faults. If high memory usage occurs when processing data, the device can generate an alarm. This enables you to monitor memory usage and optimize system performance.
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.
The memory usage configuration is displayed.
The system view is displayed.
The memory usage alarm threshold is set.
If the memory capacity on the device is lower than or equal to 512 MB, the memory usage alarm threshold is 85% and the memory usage alarm recovery threshold is 80%.
If the memory capacity on the device is larger than 512 MB and smaller than or equal to 1.5 GB, the memory usage alarm threshold is 90% and the memory usage alarm recovery threshold is 85%.
If the memory capacity on the device is higher than 1.5 GB, the memory usage alarm threshold is 95% and the memory usage alarm recovery threshold is 90%.
