Bandwidth monitor?
 

I'm looking for a lightweight bandwidth/network throughput monitor for Panther with the ability to display accumulated throughput.

I have a hard daily limit on my internet connection at school, and going over carries with it a one week suspension. :eek:

It would be nice, but not necessary, if it could reset the totals every day at midnight. If it's AppleScriptable, I can write a script to do that anyway.

A friend of mine told me that ifconfig could be used to determine total throughput for a particular interface, since it had been brought up. Totals could be reset by either bringing the interface down and immediately up, or by logging the total every day at midnight and then subtracting it from the new total... this being done by a complex Perl script of course. But I can't figure out how to make ifconfig do this... the manpages don't give any information about it.

NetMonitor (http://homepage.mac.com/rominar/net.html) is the first tool that comes to mind; it shows you transmit and receive totals for any ppp or ethernet interface, and it resets the numbers when you quit the app and start it up again. It's a ten dollar shareware.

If you're on a tight budget, X Resource Graph (http://www.starcoder.com/xrg/) is free. It shows only total bandwidth since XRG was started.

Haven't looked at command-line tools, but it seems there must be something out there like ethereal that's geared towards monitoring your internet connection.

Addendum: Got looking at the ethereal site to see if it could do anything for you and found a link to ntop (http://www.ntop.org/ntop.html). Seems to be a very complete network monitor for unix that is accessed through your web browser. If you need something more than the utilities above provide, you might want to check it out.

I recommend MenuMeters - the network part is a little set of arrows in the menubar showing current upload/download rates. It has the total uploaded and downloaded if you click on it. However, these totals do reset if/when you shutdown (or log off?).

Not exactly certain of what you are looking for, but try this URL.

And if a more expensive but more powerful tool is an option try IPNetMonitorX

Activity Monitor
 

The network tab in Activity Monitor shows you network activity, and includes a running total. This is a total since boot, so if you reboot, your data totals will be reset.
