I added Performance Counters that are available under \MSSQL$<Instance>\GeneralStatistics through Data Collector. But, values of those counters are not actually capturing and also not getting uploaded into management datawarehouse. I see empty space around "SQL Server Activity" section on "Server Activity" Report in Data Collector.
I am not sure it is PerfMon issue or Data Collector issue. The values of same set of counters are getting collected properly on other servers.
The server that I have issue is one of the node on 2 node A/A cluster. Each node runs a named SQL Server 2008 R2 SQL instance.
OS Version is Windows Server 2008 R2.
