An OSGi Monitoring System to Support Dynamicity and to Enhance Fault Tolerance of OSGi Systems

Abstract

This work addresses the problem of monitoring stateful services on a dynamic service-oriented architecture (SOA), such as OSGi. Indeed, in such architecture, services may disappear and appear, and if a used service disappears, then the client doesn't receive any notification. In such cases, classical monitoring approaches with statically linked monitors into services cannot be used. In this paper, we propose an OSGi based runtime monitoring system which enables to make security and self-healablility enforcement of dynamic services. For monitoring coherent stateful services usage, a transactional approach is defined to preserve the current run and collected data. In order to proof the validation of this solution, we give an implementation guidelines based on OSGi platform.
