Hi,
I dont think the ASA alone can give you a really clear picture of the real time situation.
It however should be able to give you some clue and simple statistics on the ASDM Firewall Dashboard
My ASDM version is 7.1 but it should be there in your version also.

My view doesnt list anything yet since I just enabled it for a new timerange. Before this it listed information for the options you can see in this windows "Top" statistics.
