I'm running SQL Server 2008 R2 Developer on Windows 7 x64, as the default instance. For some reason, SQL Server's performance counters seem to have disappeared. SELECT * FROM sys.dm_os_performance_counters returns zero rows.

I tried running lodctr /T:perf-MSSQLSERVERsqlctr.ini. Although it completed without errors, it didn't fix anything, even after restarting the Remote Registry service. In fact, the counters are now missing from perfmon. unlodctr MSSQLSERVER still says that the counters are not installed, but lodctr /Q:MSSQLSERVER says they're present and enabled. Regular Windows and .NET counters are working fine.

In the Windows Error log, I'm seeing Error 8317:

Cannot query value 'First Counter' associated with registry key 'HKLM\SYSTEM\CurrentControlSet\Services\MSSQLSERVER\Performance'. SQL Server performance counters are disabled.

I suspect the problem may have been triggered by an installation of SQL 2012 RC0 that failed. Any suggestions for how to recover, short of reinstalling SQL Server 2008 R2?

  • You mean "Visual Studio 11" (not "2011"?)

  • Yes, VS 11. The problem with the question on serverfault is that none of the posted answers resolved the issue. I'm hoping DBA-oriented users might be able to provide more useful help.

Have a try with lodctr /R, it will rebuild all performance counters from informations stored in registry.

  • In my case there were more counters missing, not only SQL Server's. lodctr /R did the trick and restored them all. Thank you very much for the trick.

Read through this:


The exact instructions are not 100% correct. You need to do this, assuming you are using the default instance:

lodctr perf-MSSQLSERVERsqlperf.ini

Then reboot.

  • I found that symbolfile path in my perf-MSSQLSERVERsqlctr.ini was incorrect. I fixed it, executed lodctr /T:perf-MSSQLSERVERsqlctr.ini, lodctr perf-MSSQLSERVERsqlctr.ini and restarted SQL Server. Commented May 2, 2015 at 13:44

It looks like the Performance Counters for SQL Server are DISABLED or the registry entries for the performance counters are corrupted.

lodctr /E:MSSQLSERVER will reload the performance counter registry settings.


Missing performance counters is recurring issue.

Some known solutions are listed here: Link


If you're running a 32-bit version of SQL Server on a 64-bit installation of Windows you need to use the 32-bit version of Performance Monitor to view the counters as explained in this MSDN Blog. Do so using either of these methods:

  1. Run perfmon.exe from the %windir%\SysWOW64 folder
  2. Run the command mmc /32 perfmon.msc

Also, make sure you're running SQL Server with the latest Service Pack and Hotfixes. MSKB article 2708726 describes an issue where Performance Monitor .dll files don't get updated properly when applying updates to SQL Server 2008 R2 or SQL Server 2012.
