  |  | The usage of ROOT for Online Monitoring in the ALICE DATE system |  
    CERNGSI Speaker: 
Roberto DiviaData Acquisition systems for HEP applications need constant monitoring
(online and offline) of their data streams to accomplish several tasks:
quality checking, tuning, statistics, pre-analysis. Monitoring tasks can 
and should use the same tools as data analysis products (conventions, 
libraries, environments) to reduce training, installation, development 
and support efforts and - at the same time - to strengthen the liaison 
between the online and the offline worlds. The ALICE DATE Data Acquisition
system available today for R&D and for test beams is fully integrated with
the ROOT environment. A simple DAQ-oriented approach and a more complex 
OO-based model have been developed to allow a variety of programming 
paradigms and to validate the complete life cycle of monitoring tools, 
both for online and offline environments.
