For the purposes of this guide, alarms, events, and traps are defined as follows:
Events are classified into the following types as shown in the following table.
Reported alarms that are enabled to appear in the Alarm Dashboard all have associated clearing events. A clearing event deletes the associated critical, major, and minor alarm from the Alarm Dashboard panel and reduces the alarm count for the corresponding severity type.
Clearing events never appear in the Alarm Dashboard and do not increment the count of a severity type.
Some critical, major, and minor alarms also never appear in the Alarm Dashboard and do not increment the severity type.
Event Types and Severity Levels
Event Type | Description | Appears in Dashboard |
---|---|---|
Critical | The critical event severity level indicates that a service affecting condition has occurred and immediate corrective action is required. Such a severity can be reported, for example, when an application becomes totally out of service and its capability must be restored. For example:
| Yes |
Major | The major event severity level indicates that a service affecting condition has occurred and urgent corrective action is required. Such a severity can be reported, for example, when there is a severe degradation in the capability of the application and its full capability must be restored. For example:
| Yes |
Minor | The minor event severity level indicates the existence of a non-service affecting fault condition and that corrective action should be taken to prevent a more serious fault. Such a severity can be reported, for example, when the detected alarm condition is not currently degrading the capacity of the system. | Yes |
Warning | The warning event severity level indicates the detection of a potential or impending service-affecting fault before any significant effects have been registered. Action should be taken to further diagnose (if necessary) and correct the problem in order to prevent it from becoming a more serious service-affecting fault. | No |
Clearing | The clearing event severity level indicates the clearing of previously reported alarms. All critical, major, and minor alarms require a corresponding clearing event. When the Alarm Dashboard receives a clearing event, the alarm associated with the clearing event is removed from the Alarm Dashboard. | No |
