Hi,

I've found tons of bandwidth monitoring softwares, but they are all too complicated to set up, or too simple for what I want.

I am looking for a tool that will produce a graph of the bandwidth used by every network interface, in the same graph.
Most of the tools I found let you monitor only one interface at a time, but I want a graphical output with the bandwidth used by every interface (separately).

Can you help me?

Thanks.

Well, the simplest and smartest is xnetload. You can also try gkrellm.

Hi, sorry to reply this late.

First of all, thanks for the reply.

xnetload seems good and does what I want, but I am looking for something that can output the graphs in a more "professional way" (i.e. not text-based).

If you know cacti, those are the graph style I need.
I tried to use cacti, but it seems that it can output only long-term statistics (e.g. bandwidth usage in the last 15 minutes and so on), while I want real-time bandwidth usage.

For example, if I download a file, I want to see the graph of the bandwidth during the download operation.
