The pair of attributes (alarm_id, entity_instance_id) uniquely identifies an active alarm:

alarm_id: An ID identifying the particular alarm condition. Note that there are some alarm conditions, such as administratively locked, that can be raised by more than one entity-instance-id.
entity_instance_id: Type and instance information of the object raising the alarm. A period-separated list of (key, value) pairs, representing the containment structure of the overall entity instance. This structure is used for processing hierarchical clearing of alarms.
