Abstract
Abstract An overview and results of the effort to monitor and measure the relevant quantities of the Resistive Plate Chamber detectors are presented, addressing in particular three aspects. First, the full exploitation of the high-precision tracking provided by ATLAS Monitored Drift Tubes when measuring the performance of the RPCs. Second, the use of a dedicated data stream to achieve the required statistics. Last, the central role of GRID facilities in providing the necessary computing resources.
