Correlated Anomalies

Correlated anomalies reduce alarm overload and help cull out false positives so you can focus on the events that are most likely to be issues. CA Anomaly Detector provides an Enterprise-Wide Correlated Anomalies view in CA NetQoS Performance Center that highlights correlated anomalies. You can navigate from this view to more detailed information while you investigate. A correlated anomaly meets the following minimum requirements:

• Contains three or more anomaly instances
• Has an anomaly index of 2.0 or more
• Originates from a single device

An anomaly index of 2.0 or more indicates the presence of two or more primary anomalies or one primary anomaly and two or more secondary anomalies.

This cross-data source, temporal clustering provides actionable workflows that support a fast, proactive response to issues. For more information about the Enterprise-Wide Correlated Anomalies view, see Enterprise-Wide Correlated Anomalies.
