Software components monitoring

software components, web services, distributed diagnosis

Web-services cover nowadays more and more application areas, from travel booking to goods supplying in supermarkets or the management of an e-learning platform. Such applications need to process requests from users and other services on line, and respond accurately in real time. Errors may occur, which need to be addressed in order to still be able to provide the correct response with a satisfactory quality of service (QoS): on-line monitoring, especially diagnosis and repair capabilities, becomes then a crucial concern.

We have been working on this problem within the WS-DIAMOND project [61] , a large European funded project involving eight partners in Italy, France, Austria and Netherlands .

We do not work anymore on the diagnosis of web services, now we aim at coupling diagnosing and repair, in order to implement adaptive web services. We started this study by proposing an architecture inspired from the one developed during the WS-DIAMOND project and dedicated to the adaptive processing when faults occur and propagate through the orchestration.
