BASETRAP_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])

The CPU usage exceeds the threshold.


Alarm ID Alarm Severity Alarm Type Major processingErrorAlarm(4)


Name Meaning
[oid] Indicates the ID of the MIB object.
Index Indicates the index of the entity. The entity in an alarm on the CPU is a board.
BaseUsagePhyIndex Indicates the index of the physical entity. The entity in an alarm on the CPU is a board.
UsageType Indicates the type of the alarm on usage.
UsageIndex Indicates the index of the sub-entity of the alarm entity. In the alarm on CPU usage, the fixed value of this parameter is 0.
Severity Indicates the severity level of the alarm.
ProbableCause Indicates the possible cause of the alarm. The code of the possible cause is as follows:

154: IANAITUPROBABLECAUSE_OUTOFCPUCYCLES indicates that the CPU usage exceeds the threshold.

EventType Indicates the alarm type:
  • communicationsAlarm (2): alarm for communication problems
  • qualityOfServiceAlarm (3): alarm for service quality
  • processingErrorAlarm (4): alarm for processing errors
  • equipmentAlarm (5): alarm for the equipment
  • environmentalAlarm (6): alarm for the environment

This alarm is of the processingErrorAlarm type, that is, the alarm for processing errors.

PhysicalName Indicates the name of the entity. In the alarm, this parameter indicates a board.
RelativeResource Indicates the resources that are associated with the alarm. The current value on the device is empty.
UsageValue Indicates the current CPU usage of the board.
UsageUnit Indicates the unit of the CPU usage. The unit is percent.
UsageThreshold Indicates the alarm threshold of the CPU usage.

Impact on the System

High CPU usage in a very short period does not affect services; however, long-term high CPU usage may delay service processing.

Possible Causes

Cause 1:

The alarm threshold of the CPU usage is low.

Cause 2:

The switch provides too many services.

Cause 3:

The switch is attacked, causing high CPU usage.
