It means that there is no performance counters in windows server that MP is looking for. How this happens I don’t know but to get it back (base performance counters) read this KB: http://support.microsoft.com/kb/300956/en-us
I was going easy way and restored first base performance counters (if any were deleted):
Performance counters for SQL are in different location so how to get it. Go to SQL installation folder and follow this commands:
cd C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Binn (go to binn folder of sql installation)
unlodctr MSSQLSERVER (unload performance counter that maybe left installed)
lodctr perf-MSSQLSERVERsqlctr.ini (load performance counters for MSSQLSERVER default instance. For named instance you should use this format perf- MSSQL$NombreInstanciasqlctr.ini)
After that restart Remote registry and Performance Logs & Alerts if necessary. Restart management agent on server in question and wait for some time to get data in SCOM dashboard for more detail about restoring SQL performance counters visit http://blogs.technet.com/b/pfelatam/archive/2011/08/08/sql-performance-counters-are-missing.aspx
I hope I helped and that you get yours performance data in SCOM dashboard.
