A client - server based online monitoring system based on ROOT,QT and OpenGL for the use in the HADES experiment. — •Jörn Wüstenfeld — Johann - Wolfgang Goethe Universität Frankfurt, Institut für Kernphysik August-Euler-Strase 6 D-60486 Frankfurt / M

Even though the prices for CPU’s and memory are low, no experiment has ever enought computing power available. Therefore new techniques for the online/offline analysis have to be developed. One possible way is to use a client - server model, where the computing intensive part is done on one central machine with fast CPU’s and big memory, while the displaying task is hosted by decentral machines with less computing power.
Following this concept, a monitoring system has been implemented in the HADES analysis framework. Besides basic functionalities it provides global detector performace monitoring and a 3D eventdisplay of HADES.
The talk will present the conceptual design of the monitoring system and a demonstration of the achieved monitor capabilities.
