Maps to the HADR_CHANGE_NOTIFIER_TERMINATION_SYNC map_value in sys.dm_xe_map_values (thanks to Jonathan’s post here).

The map_key value in sys.dm_xe_map_values is 758 in 2012 and 776 in 2014 RTM. After 2014 RTM, you must check the DMV to get the latest value as some map_key values have changed in later builds.
