Grapher 7

[Barb Magario]

Doyou 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.

noah.org lists quite a few tools that are good for examining, scraping, and visualizing network traffic. So far, the one I find pretty interesting is etherape. I even found out that some flash plugin is going to llwn.net (LimeWire!!!). I'll be checking that out. There were other tools there also that I liked but haven't tried out yet: darkstat, and ttt. Both are on noah.org. "ttt" will also graph your bandwidth by protocol.

Use the grapher to answer graphing questions. Plot your graphs on a grid and create different types of graphs using the palette of tools. Whether you use the small/large grapher, the drawing tool palette has the same icons and buttons. The displayed drawing tools depend on the type of graph you need to plot.
