I have a single application that seems to be a network pig (based on a casual glance at its logs - it seems awfully chatty). I'd like to find out what its bandwidth usage is - preferably in the form of a summary timeline, e.g., incoming/outgoing total bytes every minute (alternatively, in a form I can summarize that way myself with other tools).
If it is something that can be done with standard tools like iftop, netstat, etc., I don't know how to arrange that, so instructions (or pointer to instructions) would be appreciated.
Linux (not Ubuntu).
