IP/host-based traffic grapher

Do you know/recommend any tool for graphing traffic based on IP or host? In this case, I will get a graph for every IP that passes through my gateway. Of course, I will use a predefined list of source IP addresses. This is useful to monitor the traffic usage of all hosts inside your network.

I am using nagios grapher to graph the network traffic, but this tool graph the total traffic passing through the system interface(s). Nagios uses a script to monitor the traffic of the interface. After that, the traffic data is passed to nagios grapher.

I need to install such a tool on my Linux server/gateway.

• You might take a look at ntop.

  zerolagtime : Why is "look at ntop" or "look at atop" the common answer here? What the user is trying to do is **visualize** their traffic, not look at a boring chart or linear graph. I saw some responses to similar traffic lately that says that `iptables` is able to do some accounting. Then, someone is going to have to poll those statistics and visualize them. Standard model-view-controller problem. Model the data using iptables, view as a graph, controller directs selected data to the graph.

  : ntop can visualize traffic based on IPs as described. zerolagtime, do you know of something that works better that you can contribute?
