Wireshark is widely acknowledged as one of the best network monitor tools available. Distributions are available for OS X.If you prefer something more simplistic you can use iStatMenus to show incoming/outgoing network traffic speeds.For the person who doesn't want to install anything you can also use tcpdump in Terminal.tcpdump -i (interface, en0 is ethernet, en1 is wireless)
