A data quality monitoring software framework for the BESIII experiment

Abstract

Data quality monitoring (DQM) plays an important role in data taking at the BESIII experiments. DQM is used to monitor detector status and data quality. A DQM framework (DQMF) has been developed to make it possible to reuse the BESIII offline reconstruction system in the online environment. In this framework, the DQMF can also simulate a virtual data taking environment, transfer events to the event display, publish histograms to a histogram presenter in a fixed interval, and dump histograms into a ROOT file. The DQMF has been stably running throughout BESIII data taking.
