Abstract :
The complexity of the HEP detectors for LHC (CMS tracker has more than 50 millions of electronic channels) makes the task of monitoring of the detector performance and of the data quality on-line challenging because of the large amount of data and information to be processed. The availability of the grid computing environment opens new possibilities to perform this task, by profiting from the distributed resources in remote sites. As the computing resources may be scarce in the CMS control room it is proposed to send a sizeable amount of tracker raw data to a specialized tier-2 center through an high-bandwidth connection. This center have to be able to analyze the data as soon as they arrive, doing a quasi-online monitoring and sending back to the control room the result of this analysis. The feasibility test performed using a grid farm of INFN (tier-2) in Bari is described
