Mathematical modeling of the performance of a computer system

Generally the management of computer systems is manual; autonomic computing by self-management tries to minimize human intervention using autonomic controllers; for this, first the mathematical modeling of the system under study is performed, then is designed a controller that governs the behavior of the system. In this case, the determination of the mathematical model of a web server is based on a black box model by system identification, using data collected and stored in its own log during operation of the computer system under study.
