Impact Events

The Impact Events view shows summary and detail information about events that are affecting a service.

The following example shows an Impact Events view with key features highlighted. The last event in the details area is expanded to show the Impact chain, which is the hierarchy of service model members that are associated with the event.

Root-cause analysis (RCA) confidence rankings

The second column of the details list contains the event's confidence ranking. Service Impact knows which members affect which service models, and automatically performs RCA when an event occurs. The analysis yields a probability value that an event is the cause of the service's current state. Often, multiple events contribute to a state, so the confidence rankings enable you to quickly focus resources on the most likely cause.
