set memory-usage threshold

set memory-usage threshold


The set memory-usage threshold command sets the memory usage threshold.

The undo set memory-usage threshold command restores the default memory usage threshold.

By default:
  • If the device memory is less than or equal to 128 MB, the memory usage alarm threshold is 84%.
  • If the device memory is larger than 128 MB, the memory usage alarm threshold is 90%.

Parameter Description Value
threshold threshold-value

Specifies the memory usage threshold.

The value is an integer that ranges from 75 to 86 if the device memory is smaller than or greater to 128 MB and ranges from 75 to 92 if the device memory is larger than 128 MB.

Usage Guidelines

Usage Scenario

You can use the set memory-usage threshold command to set the memory usage threshold. When memory usage exceeds the threshold, the system logs the event and generates an alarm. By viewing log information, you can learn about memory usage.


You are advised to use the default threshold. If the memory usage threshold is set too low, the system frequently generates alarms. If the memory usage threshold is set too high, you cannot learn about memory usage in a timely manner.

When the memory usage reaches threshold-value, the level 1 alarm ENTITYTRAP_1. hwMemUtilizationRising is generated.

When the memory usage restores to (threshold-value - 3), the ENTITYTRAP_1. hwMemUtilizationResume alarm is generated.
