I encountered an issue at a customer site recently where CPU utilization on the vCenter server was very high, affecting server response time. Task Manager showed that a single process named CollectorServerHost.exe was consuming most of the CPU. With a little research I discovered this service is part of VMware Guided Consolidation. Since this customer was not using this feature, we decided to disable it. I stopped the two related services and CPU utilization dropped immediately. I tried using Add/Remove Programs to uninstall the feature, but this failed with an error.  The other VMware-recommended method of disabling the software is to edit the vpxd.cfg file using the instructions in the VMware KB article <a href="http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&amp;cmd=displayKC&amp;externalId=1003400">here</a>. Following these instructions resolved the issue for my customer.
