Thank you for your suggestion,
Unfortunately, vnstat doesn't have the provision (or at least I couldn't find it) to be able to limit the logging to 1 device. I am running iftop on a server and want to monitor 1 device on the network.

Hello,
I am looking to find a way to record data usage from a specific device on my network. Ideally the out out would be a text file with the total usage. Is there a way to have iftop run in the background and have it update a file.
If not, is there another utility that people know about the might be able to help me?
there is also vnstat which logs accumulated traffic even on multiple interfaces.
Regards,
Markus
