Can't read performance counters for an OPCInt instance

Question asked by Guilherme Ferreira Champion on Sep 20, 2018

Hi all!


In an interface node, I have three OPCInt instances.

I can read performance counter for just one of them.



I have tried rebuilding Widows performance counters and fixing specific PI counters via pidiag, but it didn't work.


  1. Open Cmd Prompt as an Administrator
  2. Navigate to C:\Windows\System32.
  3. Run Iodctr /r.
  4. Now navigate to C:\Windows\SysWOW64.
  5. Run Iodctr /r.
  6. Now Navigate to %piserver%\PIPC\adm.
  7. Run the pidiag.exe –cpc –fix.


I see in the registry that the services I can't read do not have a "Performance" subfolder like the other that I can does.



I have tried uninstalling and reinstalling the services to see if something would chance in the registry, but it didn't.


Any ideas?
