If you are in vSphere and click on Performance, you may end up running across this error:

After researching the issue I found a couple <a href="http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&amp;docType=kc&amp;externalId=1012812&amp;sliceId=1&amp;docTypeID=DT_KB_1_1&amp;dialogID=177569283&amp;stateId=0%200%20177567549">VMware KB Articles </a>on the subject, but no conclusive fix to the issue that resolved the issue. After digging in I found that troubleshooting futher proved better results. Here's the fix:

1. In my case the DB resides on a Server 2008 R2 box, so ensure you have the SQL 2008 Native Client Driver in place for your ODBC connection

2. Review the stats.log in the following location: C:ProgramDataVMwareVirtualCenter &amp; look for anything that might catch your eye (failures, etc)

3. Ensure the following services are set to an active domain account (not a local system account):

* <strong>VMware VirtualCenter Management Webservices</strong>

* <strong>VMware VirtualCenter Server</strong>

Start those services with the proper network account, then log back into Virtual Center. You should not see the "Performance" tab Overview page displaying correctly.
