Netowork Activity monitor does work and is very good.
If you are connected to the intrernet and downloading anything or if you are copying files from your server the graph does move.
Thisi s how it works :

Note:
The toolbar options and menu commands may or may not appear. Their appearance depends on how your administrator configured the client.
