Hi All, We have a scenario where we are adding custom fragments to the alarm which is allowed by the API. But to fetch alarms based on custom fragment is missing in the API spec.

Yes its mentioned for managed object but not for alarms and events.

The functionality is not available for events, and should be used carefully with alarms as it is not a very performant search. This is why it is not documented.
