The Anomaly History screen displays a history of detected anomalies that you can analyze to detect patterns of network behavior. For example, how many anomalies were from a specific device. To access the Anomaly History screen, click on Anomaly History under the “Anomaly Monitoring” section of the OmniVista Network Advisor menu.
The Anomaly History screen automatically refreshes on a regular basis to display new anomaly notifications that were received. The top section of the screen provides display filters to display anomalies detected during a specific window of time and/or search for a certain type of anomaly.
