Webmin/virtualmin do a great job of logging bandwidth usage for email, ftp, and web.  However, I want to log other bandwidth also.  Like, if they use wget in the shell to download a huge file, I want that counted towards their bandwidth.
How can I add the bandwidth for activities they do in the shell to the overall bandwidth virtualmin/webmin already count?
Not sure if this is possible, but I sure need/want it.
