This object identifies the resource under alarm. The resource id can be determined based on the varbind # that determines the resource id. The mapping of which varbind defines the resource id is defined in the zhoneAlarmModelTable. For every alarmTypeId, there is a definition of which traps set/clear that alarm and the varbind number that determines the object instance that the alarm is raised/cleared (resource id). If there is no corresponding resource, then the value of this object is 0.0.
