HowTo: Find ESX Server UUID aka Host ID

Recently I had a need to find the Host ID / UUID of an ESX server for some maintenance tasks.  However it was not nearly as easy as I thought it would be.  After googling around for a bit, I found a link that said I could use the following URL:

https://<ESX HOST IP>/mob/?moid=ha-host&doPath=hardware.systemInfo

Of course you will need your host user/password to access the info.
