Abstract:

Service monitoring is needed for meeting regulatory requirements and for verifying compliance to Service Level Agreements (SLAs). As such, monitoring is an essential part of service-based software systems. However, service monitoring comes with a cost, including impacts on the quality of the monitored services and systems. To deliver the best value to the service provider, it is important to strike the right balance between meeting monitoring requirements and reducing monitoring impacts, even as the system and its requirements change. To achieve this balance, this talk introduces a novel approach to the dynamic quality-aware configuration and optimization of service monitoring systems. It includes an automated run-time measurement and management system and an efficient (re)optimization algorithm for (re)configuring a suite of service monitors. A range of experiments have been conducted, which shows that our run-time optimization delivers significant benefits in terms of meeting monitoring requirements and minimizing monitoring impacts, and our optimization algorithm is fast enough to re-optimize large-scale monitoring systems at run-time.
