Abstract

Distributed software systems would benefit from autonomous fault management capabilities, but current practice is only based on handling exceptions without attempts at identifying causes for them. This paper is a step toward Web Services with autonomous diagnostic capabilities. It provides a novel context of application for model-based diagnosis, a contex which motivates a partially distributed approach. We consider complex services, built as a composition of simpler ones, and we associate a diagnoser with each component service, and a global diagnoser with the complex one.We characterize local diagnosers, based on abstract models of individual services, and we present the coordination protocol adopted by the global diagnoser.
