A workload event is an unplanned event, such as a high number of active requests. Use workload events to transition to different health conditions when the events occur. For example, select Active Requests as the event type and set a threshold for the number of queries that can be active at one time. When the threshold is met or exceeded, the workload event triggers a change in the health condition.
To create an event that only sends out a notification, create the event but do not assign it to any health condition. When the event occurs, the notification action you specified is triggered.
