Beta multisite, Auto/Updates, low hanging fruit?

Currently 150 hosts (to migrate ~2000 from prior monitoring) not including cloud. So not big, often just awkward when only monitoring allowed. We just have the one server.

I’m still unsure how to automate getting " Our host name in the monitoring: myhost " needed from the example. Do you just assume that it is perfect match to %COMPUTERNAME% with no name clash?
