Q. I’ve 2 Linux servers in remote data center for gaming. How do I see my current bandwidth usage for both of my servers?
A. Linux or UNIX server can use
MRTG graphs to display bandwidth usage. MRTG (Multi Router Traffic Grapher) is free software for monitoring the traffic load on network links. It allows the user to see traffic load on a network over time in graphical form.
MRTG displays graphs for 24 hrs, weekly, monthly and previous month usage. In most cases your IDC should provide the same. If not you can install MRTG on your own server by following these instructions.
You can also use tool called vnstat
