Connection failed (Bad data)

Postby Lynchie435 » Wed May 29, 2013 5:07 pm


I seem to be having an issue with my perfmon and getting the SQL Monitor to connect to the data.

I have previously looked at an older post saying this is an issue between 32bit and 64bit OS/SQL. I can confirm that I am on both 64bit OS and 64bit SQL and still have the issue.

I get the following in the log:

Perfmon data is missing objects: SQLServer:Access Methods, SQLServer:Buffer Manager, SQLServer:Databases, SQLServer:General Statistics, SQLServer:Latches, SQLServer:Locks, SQLServer:Memory Manager, SQLServer:SQL Statistics. Possible causes include performance counter library corruption, or a 32-bit/64-bit mismatch between Windows and the performance counter provider (e.g. SQL Server).

I can confirm that these objects do exist as I can select them from the performance monitor from within Task Manager and can view the data myself.

Can some light be shed please.

Please consider this resolved.

We had to perform a reboot of the server this evening after some work was carried out with our bespoke software solution and this resolved the perfmon issues.

Many Thanks
