GD The better man.

GD is Gunga Din. GD and his friends will watch the borders. They monitor all incoming and outgoing traffic. They show you your active Internet connections.

How It Works

There's very little to do here - the app is extremely user friendly. Just start it up. You can drag anything in its window to a text editor such as Rixedit but you'd best pause the program's activity first (⌘P).

GD's snapshots of your connectivity will pick up things your firewall won't. And GD can log them too.

And you can set the interval between snapshots as low as a single microsecond.
