摘要:

在线数据质量监控(DQM)在高能物理实验数据采集过程中起着重要作用。BESIII DQM从在线数据流中采样数据,使用离线重建软件进行重建,并使用用户定义的算法自动分析重建的数据。DQM软件是一个可扩展的分布式系统。监控结果以各种格式收集和显示,这为换档器提供了当前运行信息,可用于早期发现问题。本文介绍了北京谱仪研究所DQM系统的概况。

英文摘要:

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.
