Abstract: In order to improve the performance and the QoS of Apache server constantly, an adaptive tuning mechanism for Apache based on real time monitoring is introduced, which uses an analytic performance model combined with combinatorial search techniques to complete some tuning tasks as the workload changing. A model with this mechanism is designed into Apache, and the function of each module, the technology and algorithm of model is depicted. An experiment is conducted for evaluating the efficiency of this mechanism.

Key words: Apache, real-time monitoring, analytic performance model, quality of service(QoS)
