Q.  What are the functionalities of the correlation engine in Cisco Nexus Dashboard Insights?

A.   The correlation engine is used to dynamically correlate raw telemetry data across the network from each node to give useful insights. For example: If there is a routing layer problem, the application can measure and evaluate the resources across Layer 1, Layer 2, and Layer 3 to root-cause the issue. The correlation engine also stitches the flows together using tuple and timestamp information to give complete end-to-end flow path, latency, and ingress/egress information. It is also used to evaluate packet drops, including the exact point in the network where the drops occur and the reason for the drops. The correlation engine is one of the most important microservices in Cisco Nexus Dashboard Insights.
