Anyone have any insight as to how to do this?
You're gonna need to use SAM to collect those metrics with SolarWinds. I'm pretty sure they're not natively gathered via AssetInventory. If you only need a point-in-time report, you could also just run a script remotely against a list of your target devices (using PowerShell outside of SolarWinds)
These cmdlets in PowerShell should easily get you what you're after.
