How Can I Determine Whether the Memory Usage of a Device Is High?

How Can I Determine Whether the Memory Usage of a Device Is High?

Generally, the memory usage of a device is within the normal range if the following conditions are met:
  • The memory usage does not exceed 80%.
  • The memory usage does not keep increasing or fluctuate.
  • No memory usage alarm is generated.

    ENTITYTRAP_1. hwMemUtilizationRising
    ENTITYTRAP/4/ENTITYMEMORYALARM: OID [oid] Memory usage exceeded the threshold, and it may cause the system to reboot. (Index=[INTEGER], EntityPhy sicalIndex=[INTEGER], PhysicalName="[OCTET]", EntityThresholdType=[INTEGER], Ent ityThresholdValue=[INTEGER], EntityThresholdCurrent=[INTEGER],EntityTrapFaultID= [INTEGER].)
If the memory usage of a device meets the preceding conditions but the device still displays a large value (larger than 60% for example), possible causes are as follows:
  • The device is a low-end product with fewer memory resources. Therefore, the memory usage is high during the device operation.
  • The device is transmitting many services, consuming memory resources.
