Program for monitoring router traffic?

[ap3rtis]

Does anyone know of a good program that will monitor all the ethernet jacks on a router to see how much traffic each jack is using? Or do they exist? Just wondering, because the internet in this house has become terribly slow, and don't really know where/what the problem is. No one is downloading anything or gaming, and it's really slow. I guess I could just disconnect each ethernet cord 1 by 1 and see where the source is.

Linux has alot of fun features that deal with what youre looking for....

most apps have been crossed over though. Try cacti. It may be a bit advanced, but maybe worth a shot.

What router are you using ? Wallwatcher (free) can be pretty handy if you have one of the routers on it's list.

i use cacti on a network monitoring vm appliance.

easy since it's already setup and ready to go.
works well if you don't want to invest the time to set it up just to test it.
