This is a view in the mssqlsystemresource database. Returns a row per performance counter, the same counters as in Windows PerfMon, maintained by the server. To calculate a discreet value for the various per-second counters, you must sample two discrete values and then subtract the earlier cumulative per-second value from the later.

CREATE VIEW sys.dm_os_performance_counters AS
	FROM OpenRowSet(SysPerformanceCounters)
