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 |
|---|---|---|
| 1.3.6.1.4.1.2011.5.25.129.2.4.1 | Major | processingErrorAlarm(4) |
| Name | Meaning |
|---|---|
| oid | Indicates the MIB object ID of the alarm. |
| Index | Indicates the index of the entity. |
| BaseUsagePhyIndex | Indicates the index of the physical entity. |
| 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. Alarms are classified
into the following types:
This alarm is of the processingErrorAlarm type, that is, the alarm for processing errors. |
| PhysicalName | Indicates the name of the entity. |
| 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 device. |
| UsageUnit | Indicates the unit of the CPU usage. The unit is percent. |
| UsageThreshold | Indicates the alarm threshold of the CPU usage. |
High CPU usage in a very short period does not affect services; however, long-term high CPU usage may delay service processing.
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.
