Correlation Rule

Topology Correlation 

Topology-based correlation uses topology data to correlate defined related events. It is a solution that uses topology-based techniques to provide automated root cause analysis, service impact analysis, and customer impact analysis. It helps network operators identify the root causes of issues and quickly determine the services and customers affected by network events. 

Event Based Correlation Rule 

Event correlation refers to the processes involved in sensing and analyzing relationships between events. By correlating the parent and child events occurring in the network, event correlation automatically reduces the noise and allows IT to focus on those issues that really matter to the business service and IT objectives.
