Grid Service Monitoring for Grid Market Framework

With recent introduction of Web service technology into grid computing, service oriented architecture (SOA) is becoming a trend of deploying grid systems. This fosters the adoption of grid computing platforms by not only scientific research society, but also commercial enterprises. However, despite the existing technical catalysts and commercial needs, up till now, almost all research efforts are focused on using grids within academic community and the adoption of grid technology by commercial companies is still slow. We proposed a grid market framework to build commercial grid market and support the commercialization of grid, for organizations to share resources for profit. Such a framework is essential if the grid is going to evolve from its current experimental status into professional or commercial use. In such a grid market environment, the monitoring of the grid services is an important part for service status retrieval and information feedback, but it remains challenging in that the metrics for grid services are not well defined yet and existing metrics need to be revised or new metrics need to be introduced. Performance is still one of the major concerns in grid service market, and a lot of non-performance related issues are still open to be explored and few works has been done on them. In this paper, we mainly present a grid service monitoring architecture for the grid market environment. We tried to introduce and analyze some performance metrics and nontechnical metrics for various user concerns. We implemented a preliminary prototype for monitoring WSRF services with Ganglia monitor and GT4 middleware
