Hummingbird – Real Time Web Traffic Visualization
However, please note that Hummingbird is pre-alpha software. While it shouldn’t screw up your production environment, it’s definitely not yet production ready. In fact, they are still in the process of extracting it from the original app. So check it out, but don’t expect it to fulfill your greatest desires yet.
