Monitoring of Jobs and their Execution for the LHC Computing Grid

To process large amounts of data produced at the Large Hadron Col-lider at CERN, users typically submit hundreds or thousands of jobs. This requires that users can keep track of their single jobs. In this pa-per, we present a user-centric system to monitor jobs, i.e. to monitor their execution and their resource usage within such a scenario. The system supports users with useful monitoring information, interactive visualisations and helps them to nd the reasons for job failures.
