Recently rebooted one of my vCenters and came across an error on my ESXi hosts stating «Quick stats on *vmhost* is not up-to-date». A couple seconds worth of googling brought me to VMware KB2061008 which helped to resolve the issue.
However, the KB only went through the GUI process of adding in the requisite parameters but there’s no fun in clicking through the GUI so I came up with a short script that’s applicable to vCenter 6.0 which can also accomplish performing the parameter creation/updates for the KB’s workaround. Once you run the script, you’ll still need to restart the vCenter service on your VCSA or Windows server. If you happen to be in the web client: Go to «Administration» then to the «Deployment» area to select «System Configuration» Select «Services», then select «VMware vCenter Server» Select «Actions» followed by «Restart» Once the service is back up and running the error will no longer be present.
Note: this was a script that worked in my environment. There is no warranty or support with this script, please use at your own risk.
