Feature

Description

This spans the top of the chart from left to right, and indicates when alarms (represented as colored horizontal bars) were raised, changed, or canceled.

List of connections and alarms

The vertical axis of the chart contains a tree structure. The roots of the tree represent your Spotlight connections; the branches represent the alarms that have been raised for each connection. The order of the alarm branches in each connection changes to reflect the alarms that have occurred most recently.
