Real-time activity updates of multiple worker results


Using what we've learned we are going to construct a multiprocess system to track the behavior of all visitors to a sample web page. This will be composed of two main segments: a WebSocket-powered client library, which will broadcast each time a user moves a mouse, and an administration interface visualizing user interaction as well as when a user connects and disconnects from the system. Our goal is to show how a more complex system might be designed (such as one that tracks and graphs every click, swipe, or other interaction a user might make). The final administration interface will show activity graphs for several users and resemble this:

Because this system will be tracking the X and Y positions of each mouse motion made by all users, we will spread this continuous stream of data across all available machine cores using cluster, with each worker in the cluster sharing the burden of carrying the large amounts of socket data being fed...
