DQM4HEP : A generic data quality monitoring for high energy physics

Abstract

With increasingly sophisticated experiment, online Data Quality Monitoring (DQM) is of a significant importance for the detector and operation efficiency. Most experiments use their own Event Data Model (EDM) for data taking and built a dedicated monitoring system on top of it. This leads to a strong dependency to the data format and storage, making the reusability of the system for another experiment difficult. To increase the flexibility and capabilities of software across experiments, we developed DQM4HEP, a generic online Data Quality Monitoring system specifically targeted to High Energy Physics experiments. The core principle was to make no assumption on the Event Data Model and data type to treat. The result provides reusable and flexible tools for scientists to monitor their detectors by focusing only on the data analysis part. In addition, a dedicated implementation, based on the LCIO [1] Event Data Model for the Linear Collider Collaboration (LCC), was also developed. It has already been put to real condition testing during test beam campaigns at CERN1 with a combined detector setup composed of the CALICE2 Semi-Digital Hadronic CALorimeter (SDHCAL) and Silicon Tungsten Electronic Calorimeter (SiWECal) prototypes.
