- Anomaly
-
This card illustrates the anomalous activity that led to the alert.
- The blue line shows the recent anomalous activity.
- On some charts, the lightly shaded area indicates the expected (learned baseline) behavior.
A peach-shaded area represents the baseline values for the same hour one day earlier. A pink-shaded area shows the values for the same period in the previous week.
In this example, the peach-shaded area shows the data for the same hour one day earlier. The drop in the metric value (events per minute) is clearly visible.
