When you are applying a data filtering profile, look for hits in the Data Filtering section under the monitoring tab.

In Panorama, you have to use the threatID (which refers to the id of the object in Objects→Data Pattern and NOT Objects→Data Filtering. e.g. ( name-of-threatid eq 60000 )

On the firewall, you can use the name of the object or its ID. e.g. ( name-of-threatid eq 60000 ) and ( name-of-threatid eq Custom-data-pattern-name )
