Abstract

Grid systems can take advantage from monitoring services to improve the reliability from the user point of view and to accelerate diagnostic and troubleshooting. However, the distributed nature of the computing infrastructure introduces several problems regarding the implementation, deployment, updating and management of the monitoring subsystem and these problems can affect the effectiveness of the monitoring activity itself. In this paper, we illustrate a new distributed monitoring model for multiregional grid infrastructure. Stressing the IaaS paradigm and the storage auto-replica, we propose a very flexible architecture over a cloud domain extended on a geographical scale that allows to manage, reconfigure and modify each monitoring component for each site on the grid. The proposed architecture is based on a complete network management system relying on the introduction of network services that are able to create on-demand layer-2 interconnection among sites. As a case study, we present the computing infrastructure deployed in the south of Italy for scientific applications, which is based on the gLite/EMI middleware and we propose a possible scenario for supporting the grid infrastructure in Southern Italy.
