From the developer:
PacketStream provides point-and-click activation of the Mac's built-in network monitoring program, which is usually available only from the command line. By clicking a few buttons, you can monitor data as it streams over your network--especially useful for checking web traffic, network bottlenecks, or even suspicious network activity.
