The grid infrastructure for the CERN (European Organization for Nuclear Research) LHC (Large Hadron Collider) continuously operates thousands of grid services scattered around more than 300 computer centres providing more than 340,000 cores.Participating sites are organized in regions and support more than 270 virtual organizations running different middleware distributions, thus creating a very complex and heterogeneous environment.The Service Availability Monitoring (SAM) framework is responsible for the monitoring of this infrastructure.
