Lessons from M3<br />
(MDT Monitoring)<br />
• Data storage problems (slow access to tape)<br />
• Trigger prescaled (~60) due to <strong>da</strong>ta writing speed!!<br />
• Lack <strong>of</strong> calibrations available for online and <strong>of</strong>fline studies<br />
• Official procedure very slow (month) -- <strong>of</strong>fline calibration centers<br />
• Srivas calibrated with online <strong>da</strong>ta --> FAST<br />
• Detector and <strong>da</strong>ta quality monitoring<br />
• High level monitoring (<strong>of</strong>fline, tracks) }Flying<br />
• Low level monitoring (DAQ crate level)<br />
blind<br />
• Barrel MDT run for one week with wrong timing!<br />
Decided to help with MDT Online Monitoring<br />
