Fixing device hostnames after being populated
Our Logicmonitor install had a good number of devices added without PTR records and are all being identified with IP addresses. We've since fixed the reverses but doing data entry for >300 devices ...

Sorry for the delay,
My next guess is that you create a script that lists the devices trough api. For each device do a ping (in PowerShell: Test-NetConnection) extract the computername and add it to the device displayname. Again through API.
We don't have a script like that but have been talking about writing one. If or when we do we'll put it up here but that may take a while so if you haven't solved your problem yet my recommendation is start scripting. Hope it works out for you.
