Console network bandwidth monitoring
Just found this rather nifty little network traffic monitoring tool. From the blurb…
“vnStat is a console-based network traffic monitor for Linux and BSD that keeps a log of network traffic for the selected interface(s). It uses the network interface statistics provided by the kernel as information source. This means that vnStat won’t actually be sniffing any traffic and also ensures light use of system resources”
Produces a selection of nice console graphs like this:
em0 / daily
day rx | tx | total

Can also produce nice PNGs.
