Abstract:
Monitoring resources is an important aspect of the overall efficient usage and control of any distributed system. The resources of interest can include all manner of networked devices, from a remote sensor or satellite feed through to a computational node or a communications link. This generic, open-source resource monitoring architecture has been designed specifically for the Grid being an ultimate implementation yet defined for distributed architecture. A wide-area distributed system such as a Grid requires that a broad range of data be monitored and collected for a variety of tasks such as fault detection and performance monitoring, analysis, prediction and tuning. The system is based on the basics of Services Oriented Architecture, Java technologies and SNMP (agents and objects). Unlike many other monitoring systems, it is designed to monitor Grid resources and processes, rather than only the applications that execute on a Grid. It is capable of remotely observing devices, as well as gathering and displaying monitoring data.
