The DØ experiment is one of the two High-Energy proton anti-proton
collider experiments at Fermilab, USA. Since the detector serves
multiple physics purposes, it consists of many different sub-detector
systems together with supporting control systems. Therefore, online
event monitoring plays a crucial role in ensuring detector
performance and data quality by parasitically sampling of
events during the data taking. ROOT, a physics analysis package
developed at CERN, is used in the DØ online monitoring as the main
analysis tool, providing graphical user interface that interacts
remotely with an analysis executable and tools to monitor informative
histograms as they get updated throughout the data taking in the shared
memory. In this paper, we present the basic structure of the DØ
online event monitoring system and the use of ROOT in the system.
