An event is an occurrence of something interesting at a given moment. An event could be generated automatically when a stream exceeds a certain threshold or meets certain criteria or patterns, or it could be an ad-hoc interesting moment as defined and specified by the user.
Each event will generate a tick mark on your timeline. Events allow for quick, simple navigation of the timeline and help one identify occurrences or states of interest along the way.
Events can be configured to trigger a notification with varying degrees of urgency (as specified by the user). It can also be configured to trigger Commands on the device or trigger ingestion of data based on configurations.
