Performance monitoring for distributed service oriented grid architecture

Computational Grids provide an emerging highly distributed computing platform for scientific computing. Recently, service oriented architecture (SOA) is a trend of implementing software systems including Grid computing systems. SOA provides more flexibilities for Grid users at the service level. Since performance is still one of the major concerns in Grid environments, Grid service performance issues needs to be extensively investigated and studied. However, a lot of issues are still open to be explored and few work has been done on them. In this paper, we propose a Grid service monitoring architecture for flexible monitoring on various Grid services. We implemented it for monitoring WSRF (Web Service Resource Framework) services in this paper. We show how the service oriented Grid monitor work with a simple example WSRF-compliant MathService. Moreover, the relationship of the monitor and Grid super scheduler is also analyzed. In this way, the scheduler may produce service performance oriented policies that ensure optimal quality of services for Grid applications.
