From the Alerts and Notifications > Alerts tab in the VMware Pulse IoT Center UI, you can search for alerts by their definition, by the update time range, and by their states (active, acknowledged, or canceled). You can also acknowledge alerts from this tab.

To acknowledge an active alert from the list of alerts, select the alert and click ACKNOWLEDGE. The alert's state changes to Acknowledged and the user name of the person who acknowledged the alert is displayed.

You can view the alert history of a device and determine if an alert is new or an existing one. You can also determine the number of times the device has raised this alert, identify the metric, value, and the time stamp when the alert was triggered. Select the alert definition and click the History tab. A graph indicating the alert states is also displayed.

A notification is sent out when an alert transitions to the CANCELLED state.
