Unity alerts notify a DBA of an event that requires attention. A summary of currently open alerts appears on the Alerts card of the Unity UI Overview screen. From this view you can easily and quickly sort for alert types and severity, and for the different types of alerts that are open. Select the alert name to see the details for each alert type.
