Something on my network is using an enormous amount of data and I need to track it down. Its not constant or predictable.
I have had a go with Wireshark and I am sure that it could tell me what I need to know via it's "Statistics" menu by looking at the bytes sent to each physical address.
The problem is I need to leave this running for many days, and wireshark (by default at least) is logging every single packet and it's contents leading to absolutely enormous and numerous log files.
I simply need to know how many bytes were sent to/from each device on our network per hour/day. I don't care about any of the other information at this stage.
