Monitoring and Control of Large Systems with MonALISA

摘要

MonALISA developers describe how it works, the key design principles behind it, and the biggest technical challenges in building it. The HEP (high energy physics) group at the California Institute of Technology started developing the MonALISA (Monitoring Agents using a Large Integrated Services Architecture) framework in 2002, aiming to provide a distributed service system capable of controlling and optimizing large-scale, data-intensive applications. Its initial target field of applications is the grid systems and the networks supporting data processing and analysis for HEP collaborations. Our strategy in trying to satisfy the demands of data-intensive applications was to move to more synergetic relationships between the applications, computing, and storage facilities and the network infrastructure.
