The BESIII is a general-purpose experiment for studying electron-positron collisions at BEPCII which is located at IHEP, Beijing, China. It works in the τ-charm region mainly. Several world’s largest samples in this region had been collected. The BESIII DQM is a lightweight online data quality monitoring (DQM) solution at BESIII. It uses the full offline reconstruction software to reconstruct a part of data for real-time monitoring the data quality. The document gives an overview of the BESIII DQM system, including the framework, main components and data flow. The DQM system separates online DAQ and offline software environment as much as possible and is easy to expand.
