“…It then fills the second-level histograms with these parameters. Some important parameters are further stored into the DQM database which is a subset of the BES offline database [7]. These parameters are used to draw a historical curve in order to make comparisons.…”

The online Data Quality Monitoring (DQM) plays an important role in the data taking process of HEP experiments. BESIII DQM samples data from online data flow, reconstructs them with offline reconstruction software, and automatically analyzes the reconstructed data with user-defined algorithms. The DQM software is a scalable distributed system. The monitored results are gathered and displayed in various formats, which provides the shifter with current run information that can be used to find problems early. This paper gives an overview of DQM system at BESIII.
