Hah, I wrote something very, very similar to this recently. The problem I eventually had with it was that lsof wasn't always installed on the hosts I was working with. So, it turned into a script to parse through /proc and other nonsense. https://github.com/red-bin/lsofer/blob/master/lsofer.sh https://github.com/red-bin/lsofer/blob/master/lsofer.sh (wish I could paste the graphing code, but it's code I wrote at my company.)
