Hi all

I have been running iptraf on a linux box for a few months monitoring bandwidth utilization realtime from mac address with port mirroring.

Now I want to graph these bandwidth utilization. Is MRTG the right software?

Any ideas?

why don't you try cacti, it's nice for bandwith graphs

Cacti is alright but I need something that monitors throughput on a per mac address basis. I have tried ntop. Its good but not quite there. Don't want to use SNMP.

Combination of both is industry wide implemented. People run rrdtool from cron to collect periodic data and then MRTG graphs been generated from those RRDs.
It require to first design RRD as per your requirement and then write down some shell-scripts to update RRD and generate MRTG.

You could try AdventNet ManageEngine NetFlowAnalyzer. There is a free version that will allow the monitoring of 2 router interfaces. If you plan carefully you can catch all the traffic at least to the internet. It will filter down to the host level also telling you what type of traffic is being used. Some apps you may have to setup the ports and what they're being used for.
