Solarwinds - Identifying Windows Server Core vs Gui

We have a mixture of Microsoft Windows Servers (2008, 2012, 2016) in our environment.

Currently we are trying to figure out best practice to identify the Server Core versions from the Gui versions in the monitors.

There are several items that we've looked at without success so far

- Versions (it's the same for each year)

Investigating server manager components and services that are different between the two as a possible option.

All suggestions are welcome.
