While working on an Orion implementation, and I ran into the appearance of a bug with VMWare 6.5 related to Hardware health polling. Hardware health in ESX 6.5 appears to be broken, but actually the services needed need to be configured to work correctly. This is a new change done in 6.5.
Issue Identified: VMWare ESX 6.5 Hardware health shows as unknown. Node Shows as Green with Grey child status. Map may show server as green with yellow status.
Error Reported: Hardware Health Unknown. "Polling of chassis (CIM_Chassis class) failed. Unable to connect to the remote server.
How to fix:
On the VMWare C Client (some functions in the C Client do not function with ESX 6.5, but everything we are doing will work)
Go into Configuration> Security Profile, Properties, select SSH, enable SSH Service
On the VMWare Web Console, go into services and enable SSH
Next: login via ssh (I used putty)
Note: This shows what you run and the expected outputs Bold text shows what you need to confirm on the screen to know that the steps are working as expected.

(This is to enable wbem)

(Next, I checked the service to make sure it is running)

Wait for the next polling cycle. Other VMWare customers have reported that restarting the server fixes the issue, but we could be talking about resolving production issues. From what I have seen, No restart is required, based on the steps above, but it can take 15-30 minutes to show up.
