Bandwidth Monitor

[RobH]

I know that this has been asked here before (I did a quick search but couldn't find it) but what is the name of the tool that allows you to monitor how much bandwidth you have used? For example if you were on a 1GB limited broadband package and you wanted to keep an eye on how much your using.

Thanks

Thanks everyone, netmeter was the program I was after, couldn't remember the name though. Going to wales this weekend and there is a hotspot broadcasting near our caravan (static) but there is a 200MB limit on it when you buy credit so I need to watch what I'm using. Is there any programs for OSX that do a similar thing?
