New fix for wrong performance data


Many thanks to Ben who posted a reply to my latest post on bad performance data collected pointing out a fix has been released on Feb 10th to address the wrong performance data points.

I just added the fix to my requirements list, if you’re serious about performance monitoring with OpsMgr on Windows 2008 / 2008 R2 then this fix must be in your MUST list:

KB 2470949 – The RegQueryValueEx function returns a very large incorrect value for the "Avg. Disk sec/Transfer" performance counter in Windows Server 2008 R2 or in Windows 7

Btw not only the Avg. Disk sec/Transfer counter is affected but at least all the disk counters. And the fix is not included in Service Pack 1 for Windows 2008 R2.

The funny thing is that, right now, the x64 fix isn’t available (I opened a PSS call for this)… So Microsoft publishes a fix for Windows 2008 R2 but you can download it only for ia64 and not for x64, interesting, isn’t it? In the past I and many others flamed the OpsMgr Team for the mess they caused with hotfixes. They listened to us and now they regularly publish cumulative updates… It’s time for the OS team to wake up, before it’s too late.
