Abstract
The Monitoring and Discovery System (MDS) is a suite of web services to monitor and discover resources and services on Grids. This system allows users to discover what resources are considered part of a Virtual Organization (VO) and to monitor those resources. MDS services provide query and subscription interfaces to arbitrarily detailed resource data and a trigger interface that can be configured to take action when pre-configured trouble conditions are met.
For more information about the information services concepts behind GT4, see Information Service: Key Concepts.
GT4’s MDS includes:
WS MDS, the WSRF implementation of MDS, which consists of:
- Index Service, , which collects monitoring and discovery information from Grid resources, and publishes it in a single location.
- Trigger Service, which collects data from resources on the grid and, if administrator defined rules match, can perform various actions.
- Aggregator Framework, the software framework on which the above WS MDS services are built.
- WebMDS, which enables end users to view monitoring information via a standard web browser interface, without installing any additional software on their PC.
