1. A method for autonomic system management comprising: maintaining within an autonomic computing system a plurality of component models, each component model associated with one of a plurality of components in the autonomic computing system, each component model simulating operation of its associated component to predict a state and performance of that component for various operational conditions of the autonomic computing system, wherein each component model is supplied to the autonomic computing system by and maintained by its associated component independent of a centralized management server and all of the component models are accessible by the centralized management server, wherein maintaining the component models comprises adding a new component model for each new component added to the autonomic computing system by: identifying new components added to the autonomic computing system; and obtaining a corresponding component model from each new component, by: establishing communication between the centralized management server and the new component; requesting a new component model from the new component; communicating a list of supported languages for the new component model from the centralized management server to the new component; reviewing all available new component models; generating a list of all new component models expressed in languages supported by the centralized management server; identifying a preferred new component model from the generated list; and communicating the identified, preferred new component model from the new component to the centralized management server; accessing the component models maintained in the autonomic computing system using the centralized management server; using the centralized management server and accessed component models to develop a system-wide model for autonomic computing system performance covering all of the components in the autonomic computing system; computing an updated operational state for the autonomic computing system using the system-wide model developed using the accessed component models, the updated operational state associated with improved autonomic computing system behavior in at least one measure of behavior over a current operational state of the autonomic computing system; and managing the autonomic computing system in accordance with the computed updated operational state.
