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_1.3.6.1.4.1.2011.5.25.219.2.15.1 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.
