The data quality monitoring challenge at CMS: Experience from first collisions and future plans

The Data Quality Monitoring (DQM) Software is a central tool in the CMS experiment. Its robustness and flexibility is critical for monitoring detector performance and providing fast and comprehensive feedback centrally for the experiment in realtime (Online DQM), after a full event processing with fine-grained analysis (Offline DQM), and as a validation tool to validate both the CMS software (CMSSW), calibration and alignment scenarios and extensive simulations. The entire DQM framework has undergone fundamental changes, and the first performance results of this newly updated system will be presented in the context of the first proton-proton collisions for CERN's Large Hadron Collider at a center of mass energy of 13 TeV. These results will encapsulate the performance of the CMS detector in the context of the upgraded DQM system that makes available more sophisticated methods for evaluating data quality, as well as a dedicated review of the technical challenges and improvements specific to the DQM framework itself.
