Impact
A monitoring tool is an essential constituent of any e-Infrastructure. Because of its crucial role and the peculiarities each infrastructure has, multiple implementations may exist. The D4Science monitoring tool, differently from the majority of existing tools that focus on computing and storage elements, enlarges the pool of tracked resources to data and services. It thus promotes novel approaches for monitoring diverse classes of resources.
The different strategies adopted to show the status of data sources as well as the one exploited to present the status of families of services and running instances interacting each other in the context of a VRE represent innovative methods that other domains can benefit from. The openness of the adopted technology as well as the adoption of standards are key characteristics making the proposed tool (i) appealing for site administrators, resource providers, and VRE managers; (ii) capable to adapt to different application scenarios.

Detailed analysis
The D4Science e-Infrastructure consists of an organized pool of distributed resources aggregated to accomplish tasks that cannot be performed by a single site. To monitor the status of its e-Infrastructure, D4Science developed a monitoring tool initially inspired by the EGEE GridMap and then refactored by exploiting GWT, Treemaps, and graph visualization tools.
The D4Science eIinfrastructure is comprised of a diverse set of resources, such as services, data, software packages and hardware that are on-demand synthesized into VREs and is equipped with a powerful Dynamic Deployment capacity. In this scenery, the comprehensive, real-time views offered by the tool are more than necessary for fine-tuning and troubleshooting. Monitoring the consumers of data resources, or the members / contributors of a VRE are two examples of domain-specific visualization offered by the tool.
Conclusions and Future Work
This demo provides an overview of the current D4Science Monitoring Tool examined in a user application scenario. The demo introduces the various operations and resources that are tracked by the tool and presents the comprehensive monitoring views given to the system administrator / user. Thanks to the tool’s openness the future plans include enlargement of the pool of alternative views currently supported by it, and thus to serve different information needs effectively.
Justification for delivering demo and technical requirements (ONLY for demonstrations)
No special technical requirements are needed besides web access.
Demonstration is appropriate for demonstrating the operation of the tool in conjunction with the unique features of the e-Infrastructure, such as Dynamic Deployment, on an environment derived from a selected user community case. An Oral presentation is feasible as well but probably less effective.
