How Can I Determine Whether CPU Usages of the System and Processes Are High?

How Can I Determine Whether CPU Usages of the System and Processes Are High?

System CPU usage is within the normal range if the following conditions are met:
  1. The CPU usage does not exceed 80% over a long period of system running.
  2. The CPU usage does not exceed 95% over a short period and does not keep increasing.
  3. No high CPU usage alarm is generated.
In the following scenarios, the system may generate an alarm when CPU usage becomes high suddenly and then clear this alarm rapidly. This situation is normal and does not affect device operation.
  1. Cards has just started.
  2. Information about all optical modules is queried at a time.
  3. Traffic volume increases suddenly.

CPU usage of a CPU task process may become low or high, depending on the service volume and processing time. CPU usage is within a normal range if the system CPU usage does not exceed 80% and no high CPU usage alarm is generated.

High CPU usage alarms are as follows:
  • Alarm (of Basetrap type)
    BASETRAP_1.3.6.1.4.1.2011.5.25.129.2.4.1 hwCPUUtilizationRisingAlarm
    BASETRAP/2/CPUUSAGERISING: OID [oid] CPU utilization exceeded the pre-alarm threshold.(Index=[INTEGER], 
    BaseUsagePhyIndex=[INTEGER], UsageType=[INTEGER], UsageIndex=[INTEGER], Severity=[INTEGER], ProbableCause=[INTEGER], 
    EventType=[INTEGER], PhysicalName="[OCTET]", RelativeResource="[OCTET]", UsageValue=[INTEGER], UsageUnit=[INTEGER], 
    UsageThreshold=[INTEGER])
  • Alarm(of the Entitytrap type)
    ENTITYTRAP_1.3.6.1.4.1.2011.5.25.219.2.14.1 hwCPUUtilizationRising
    ENTITYTRAP/4/ENTITYCPUALARM:OID [oid] CPU utilization exceeded the pre-alarm threshold.(Index=[INTEGER], 
    EntityPhysicalIndex=[INTEGER], PhysicalName=[OCTET], EntityThresholdType=[INTEGER], EntityThresholdValue=[INTEGER], 
    EntityThresholdCurrent=[INTEGER], EntityTrapFaultID=[INTEGER].)
