I'd suggest you try `darkstat`.
It's a fairly lightweight package that's easy to install/setup and which
can give you that kind of information (tho it might not be as flexible
as you like in terms of choices of time interval, and it might be more
detailed than you're requesting in terms of origin/destination).
