The Mercury Monitor is designed to satisfy requirements of grid performance monitoring: it provides monitoring data represented as metrics via both pull and push access semantics and also supports steering by controls. It supports monitoring of grid entities such as resources and applications in a generic, extensible and scalable way. It is implemented in a modular way with emphasis on simplicity, efficiency, portability and low intrusiveness on the monitored system.


The objectives of this workpackage are to design and develop a general grid monitoring infrastructure, compliant to the Grid Monitoring Architecture proposal of the Global Grid Forum Performance Working Group. The aim is to support the advanced scenarios foreseen in the GridLab project, such as application steering, self-tuning applications and performance analysis and prediction. To achieve this the general GGF GMA architecture is extended with actuators and controls. Actuators are analogous to sensors in the GGF GMA but instead of gathering information, they implement controls and provide a way to influence the system.

Components provided by other work packages (especially WP7) will be based on the services provided by this work package. Using the capabilities provided by the monitoring system together with functionality provided by other work packages it will be possible to make the monitoring system itself more intelligent and adaptive including dynamic sensor management according to the rapidly changing grid environment.

GridLab: Grid Application Toolkit and Testbed is co-funded by the European Commission under the Fifth Framework Programme (IST-2001-32133).
