In order to view the anomalies for the alerts that you create using Alert Manager, you must create an Automatic Alerts column in the Engagement Dashboard with the following details: 

• Name: Name of the Automatic Alerts column.

• Module: Select Listening, Benchmarking, Location Insights, or Product Insights. 

• Alert Name: Select the Alert that you have created using Alert Manager from the drop-down.

Once the above 3 fields are selected, save the column, and then you can see the anomalies as soon as they are detected.
