A composition of monitoring services for the LHC computing grid

The Large hadron collider (LHC) generates 12-14 petabytes of data each year, equivalent to 20 million of CDs. The LHC computing grid (LCG) is the grid infrastructure to process those data and has huge number of scientific computing centers spread across Europe, America, and Asia to meet this unprecedented computing and storage requirement. To meet those needs, the LCG is using many monitoring services. To improve and guarantee the reliability of grid infrastructure, site administrators should use several monitoring services and visit several pages for each service. In this paper, we propose a method to provide an integrated view to LCG users by using the service composition approach. With the proposed approach, we can get the reliability of site operation and the flexibility to afford new monitoring aspects. Also, we can make the monitoring process secure.
