Error: Microsoft's PDH DLL

Upgraded our trial to full version a couple of weeks ago and started getting this error for a dozen or more monitored VMs at a time out of nowhere...

Unable to monitor counters--counter data not collected. OS reports: The wait operation timed out. Troubleshooting Hint: This error occasionally happens in Microsoft's PDH DLL. To work around it, use REGEDIT and go to HKEY_LOCAL_MACHINEsoftwarePowerAdminServerMonitor. Set Perfmon_Mutex2=5 and restart the monitoring service

I cannot find the above registry key on the PA Server or the client machines. I have tried power cycling the PA server to no avail.

PDH DLL getting stuck has been an ongoing problem. Starting with version 5.7 you can use an alternate way of retrieving counters that won't use PDH DLL.

To enable it, set:

HKEY_LOCAL_MACHINEsoftware (Wow6432Node if you have it) PowerAdminServerMonitor

Perf_AvoidPDH = 1

The PA Server Monitor service needs to be restarted after making this change.

Hi Ovalis_DT

By default that registry value should be there. Would you please send me a screen shot showing me that it is not there. The email address is support@poweradmin.com

David,

Sorry about the error message... It says to got to the following location in the registry:

HKEY_LOCAL_MACHINE\software\PowerAdminServerMonitor

You have a 64-bit OS so you will need to go to this location to find the key

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PowerAdminServerMonitor

You should find the "Perfmon_Mutex2" key there. Please make the change to the key and then test to see if resolves your issue.

Thanks
Quinn
