OpManager v12 REST API

OpManager v12 REST API

Hi,

I am looking at the REST API documentation here:  http://help.opmanager.com/rest_api 
In the alert section, most APIs require the parameter 'entity'. It then adds that entity u niquely identifies the failure object within the source.Events will be correlated into alarms according to the entity field. Multiple events with the same entity will be grouped as a single alarm.
So are entities the interfaces of a certain device or are they something else? 

Thank you.
