Decent program for drawing traffic shaping graphs

Hi

I have a Linux router between my home network and a cable modem which is
happily traffic shaping and NATing etc.

One of the programs I've used to view network traffic is iftop. It's
great for looking at immediate traffic but, as far as I know, the data
isn't saved over time so a graph over time can't be drawn.

In order to analyse how the traffic shaping is going, I'd like a program
to record traffic and speed data, then I can specify a filter or two and
get a graph of them over some time period.

For example, host A has a low traffic shaping priority. Port B has a
high priority. I'd like to see a graph showing that as port B becomes
used, host A is given less bandwidth.

There are lots of programs out there to analyse network traffic, but I
haven't found one with this capability yet. I've tried nagios,
darkstat, ntop and a few others.

Thanks

Barry

Have you tried ntop? It won't survive a restart, but it'll give you
stats by IP address, connection, top, etc and some graphs. If you don't
mind a Windows thing, look at PRTG. It'll do exactly what you want,
graphing bandwidth by IP address, port, etc. You can create sensors for
inbound, outbound, point-to-point, point to any, any to point, you name
it. Free demo, 50 sensor is about $50 I think. Google.

Oops ... meant to post these 12/12 AM but was diverted.

Both Cacti and MRTG make use of RRDtool, but I have found Cacti easier
to get up and going to satisfaction. MRTG has been around longer and
there are many how-tos, extras, etc. referencing it. The articles
should give you and idea as to whether it's worth a look.

Nice one guys. Thanks for all your suggestions. I'm knee deep in
programs to use now!

Thanks again
