There may be other systems that readily do what you need. If your problem is just to graph traffic from/to multiple peers, and you cannot simply graph interface statistics because several peers share an interface (such as at an exchange point), and your routers support "MAC-address accounting", you can probably use a tool like MRTG to produce graphs for each peer's MAC address. This is easier to set up than Netflow processing, and should be more precise (the "source AS" information in Netflow cannot generally be relied upon). On the other hand, Netflow gives you many more possibilities for analyzing traffic, such as port-number information etc. -- Simon. _______________________________________________ mrtg mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/mrtg
