In Cisco Nexus Dashboard, a correlated anomaly is a secondary condition that Nexus Dashboard has associated through cause-and-effect analysis with another anomaly identified as the probable root cause. Cisco's current documentation explicitly distinguishes root-cause anomalies from correlated anomalies: the root anomaly triggers additional symptoms, and those dependent symptoms are displayed as correlated events.
For example, a physical or routing event may cause a downstream BGP session to fail. Rather than presenting each symptom as an independent failure, Nexus Dashboard analyzes relationships involving interfaces, devices, protocols, and timestamps. The BGP peer-down condition can therefore appear as correlated when a higher-level underlying anomaly explains it.
Option A incorrectly associates correlation with user-account activity. Option B describes repetition across several devices, which is not what the correlation indicator means. Option D refers generally to impact analysis rather than the specific root-cause relationship communicated by the label.
This feature reduces troubleshooting time because engineers can focus first on the root anomaly. Cisco specifically notes that resolving the underlying root cause should also resolve the anomalies correlated with that condition.
