I’ve encountered a strange situation when I could not find SQLServer:Databases group of counters in Windows Performance Monitor.
It was happened on my test system with SQL Server 2014. I checked it on production SQL Server 2008 R2 – everything is OK.
The most important thing to solve this problem was found in Windows Application Log. It was error 8310.
Simple search in Google with the error message leads me to the description of that particular problem. It’s on SQL Server 2014 installation and is corrected by installing Cumulative Update 2. I’ve installed CU7 and now it works.
