Report on SEP components

I've had a hunt around SEPM and cannot find where one can run a report on which computers/servers have the firewall installed.
I think it would be good for reporting to be able to show how many machines are running the full suite and how many might be running the AV/AS engines only.

Obviously for this kind of reporting, it would be helpful to be able to get the names of machines, not just numbers.
