You need to enable Health Monitoring first. And check Traffic Throttle setting, if it's set to None, please set it to other than None, and wait a while.  
Hi, Experts,  I have one problem. VxRail version is 7.0.201 and When I see appliances in VxRail Cluster > VxRail>Appliances, I can't see ESXi hosts. Error Messages come out "No VxRail hosts available".  Please let me know how to solve that problem. I will attach the screenshot.  [IMAGE] Thanks,
