Interpret Service Impact Incidents

The Service Impact Incidents view in the Incident Browsing workspace displays all of the incidents that have a Correlation Nature of  Service Impact. Service Impact incidents indicate a relationship between incidents in which a network service is affected by other incidents. By default, NNMi generates Service Impact incidents for Router Redundancy Groups. For example, an Interface Down incident can affect a Router Redundancy Group that is part of an HSRP service.

The Service Impact incident helps your troubleshooting efforts by identifying which service is affected.

NNMi's Causal Engine determines the Correlation Nature for an incident.

(NNMi Advanced) As an example of a Service Impact incident and its relationship with other incidents: an Interface Down incident on an interface that is part of a Router Redundancy Group can affect the integrity of a Router Redundancy Group that is part of an HSRP service. To continue the example, A Router Redundancy Group Degraded incident might be the Service Impact incident used to indicate there is a problem with your HSRP service. The Interface Down incident would appear under the Conclusions tab for the Router Redundancy Degraded incident to indicate that it is part of the reason the Router Redundancy Group (and subsequent HSRP service) has become degraded.

NNMi provides the following incidents that have a Correlation Nature of Service Impact:

NNMi determines the Correlation Nature for an incident.

See Router Redundancy Group View () for more information about Router Redundancy Groups.
