AbstractThe Globus Toolkit's Monitoring and Discovery System, (MDS) defines and implements mechanisms for service and resource discovery and monitoring in distributed environments. We introduce here MDS4, the new monitoring and discovery system component included in Globus Toolkit version 4. MDS4 is distinguished from previous similar systems by its extensive use of interfaces and behaviors defined in the new WS-Resource Framework and WS-Notification specifications, and by its deep integration into essentially every component of the Globus Toolkit. We describe the MDS4 architecture and the relevant Web Service interfaces and behaviors to allow users to discover resources and services, monitor resource and service states, receive updates on current status, and visualize monitoring results. We also describe how MDS4 can be used to implement large-scale distributed monitoring and distributed systems, and present preliminary experimental results that provide insights into the performance that can be achieved via the use of these mechanisms.
