I have grabbed Chad’s updated plugin as SQL2012 relies on sys.dm_os_performance_counters. Only the default time2connect metric works. Any other metric throws:
Caught unexpected error. This could be caused by your sys.dm_os_performance_counters not containing the proper entries for this query, and you may delete this service check.
I have verified I can get the data with a manual tsql query.
