You can configure anomaly alert settings that monitor when an anomaly, detected by
the ExtraHop Addy™ service, has occurred on specific protocols. When the conditions
configured in the alert settings are met, the ExtraHop system generates an anomaly alert,
which you can view in the Alert History.
Anomaly alerts are useful for monitoring unusual behavior that you want to be
notified of right away. For example, if you are worried about spikes in SSH sessions
on specific servers, you can configure alert settings to watch for anomalies that
occur over SSH and assign the alert configuration to SSH servers.
