Abstract: Systems and methods for response monitoring are described. A method of generating a measurement for use in calculating an end-user experience metric in a server-based computing environment includes, transmitting a message from a client of the server-based computing environment to an application executing in a user space provided by an operating system of the server, receiving a graphic response for execution by the client from the application, and determining an amount of time elapsed between the transmission of the message and the conclusion of the execution of the graphic response.
