Monitoring and Modeling Web Server Performance: A Symbiotic Simulation Approach

Abstract—Existing approaches on web server simulation are often restricted, especially with the advent of the dynamic web. We propose a symbiotic approach for web server simulation, using a Faster than Real Time Simulation environment, compatible with the Dynamic Data Driven Applications Systems concept. The corresponding framework was implemented, consisting of: a measurement module, the FRT simulator, running concurrently with the web server, a controller that manages both the measuring process and the simulator, and a network level packet sniffer. Experimental results are presented along with open research issues. Keywords-modeling; web-server simulation; symbiotic simulation; faster-than-real-time simulation I
