METHOD AND APPARATUS FOR UNIFIED PERFORMANCE MODELING WITH MONITORING AND ANALYSIS OF COMPLEX SYSTEMS

摘要

A method and apparatus (200) for unified performance modeling with monitoring and analysis of complex computer systems is disclosed. An aspect of the invention relates to performance monitoring and analysis by constructing a synthetic work load of the complex system and monitoring a parameter of the system indicative of system performance. A system deployment model and system scenario model pair are constructed from worst case scenarios of the parameter over a period of time. A system performance model (216) is extracted from system state model (214) associated with the system scenario model (210). The system performance model is modeled for point of failure occurring in the system. Another aspect provides a unified performance modeling to extract the system performance model from system state model (214). Additionally disclosed is an interactive system performance modeling using system scenario model and system deployment model pair with updated systems point of failure. Another aspect is a method for performance monitoring and analysis of a system in a grid computing environment.
