Raw X11 protocol analyser

From the original README

Xmon interactively monitors the byte-stream connections between an X server and a number of X clients. Xmon recognises all requests, events, errors and replies sent between the clients and the server which are part of the core X protocol. The contents of these messages are displayed on standard output at a user settable degree of detail from none to every bit and byte. Xmon also allows the user to select a number of requests or events to be monitored at a different degree of detail. Xmon will also block the transmission of selected requests from the clients to the server and selected events from the server to the clients. Xmon also keeps statistics of the number of requests, events, and errors received.
