Introduction

Overlay event allows to display stats of the generated alert in the graphs. We can get the alert events from Alert History. Based on its time stamp, you get annotations on the graph, to show the different types of Alerts (Critical / Major / Minor).

There are different representation for different type of Alerts:

- Red colored Background for Critical Alerts.
