Alarm MIB for Tail-f Systems. This MIB represents alarms as states, where a row in the alarm table corresponds to a device, an object within the device and an unique alarm type. If the severity of an alarm or a the clear state is changed this is an update to an existing alarm entry and not a new. When the resource reports a clear on the alarm the alarm entry still exists until administrative processes purges the alarm list. These procedures are out of the scope for this module.
