I’ve done some searching and I see some discussion on this in the past. I’m about to switch my Comcast cable account over to a program that has 1TB a month data cap.
I want to on a monthly basis track current data usage per device and a monthly grand total.
Now I’ve seen some discussion of ntopng and iptraf.
I could use ntopng and do a port mirroring on my switch to another machine… However I would like to know if anyone else has any other solutions.
