Hello, I've recently become an amateur linux server admin, mostly for the fun of building and running a linux server At the moment it runs a couple of game servers, voip, a website and backups, and I will hopefully expand it in the future. Anyway... I'm looking for an easy-to-use network monitoring tool. I'm curious to see what processes are using how much bandwidth, basically. I would like one that displays realtime data (if possible?) and also logs the data. I am a bit familiar with the linux cli and bash. Any suggestions? Thanks.
