heal.abstract	With the start of Large Hadron Collider approaching, storage and management of raw event data, as well as reconstruction and analysis data, is of crucial importance for the researchers. The CERN Advanced STORage system (CASTOR) is a hierarchical system developed at CERN, used to store physics production files and user files. CASTOR, as one of the essential software tools used by the LHC experiments, has to provide reliable services for storing and managing data. Monitoring of this complicated system is mandatory in order to assure its stable operation and improve its future performance. This paper presents the new monitoring system of CASTOR which provides operation and user request specific metrics. This system is build around a dedicated, optimized database schema. The schema is populated by PL/SQL procedures, which process a stream of incoming raw metadata from different CASTOR components, initially collected by the Distributed Logging Facility (DLF). A web interface has been developed for the visualization of the monitoring data. The different histograms and plots are created using PHP scripts which query the monitoring database. © 2010 IOP Publishing Ltd.	en
