Prerequisites
Before you use anomaly detection on the Performance page, make sure that:
You have opened the target appliance dashboard.
You have navigated to Monitoring > Performance and confirmed that the page heading shows Performance Analyser.
You have selected at least one node and at least one performance metric.
The chart shows raw performance data for the selected metric in the current time window.
Note:
Anomaly visuals depend on expected-range information being available for the selected metric and time window. If expected-range information is not available, the chart can show only the raw metric series even when Anomaly Detection is enabled.
