Is it possible to run scorecard report where you will see figures divided by desktops / windows servers / printers / network devices / etc?
Yes. You'll first need to create the appropriate Asset Groups / Tags, so these can be used while running the report.
Next, when you run your Scorecard report include the required Groups / Tags, and you'll see data like below:
What kind of report / template you run to get your results tables/chart?
