Online (GNAM) and offline (Express Stream and Tier0) monitoring produced results during cosmic/collision runs (Oct-Dec 2009)Shifter and expert level monitoring histogramsAt low level (raw and prep-raw data), mid level (cluster) and high
level (track )Online monitoring was a useful tool for CSC integration
Integrated, maintained, and validated with ATLAS softwareCSC reconstruction software validated (Sep 2009) CSC reconstruction and monitoring enabled at Tier0 (since Oct 2009)In mid-December all offline muon detector monitoring was off –
problems and solution still unclear Developed associated configuration (DQMF / OHP for online)
DQMF/ HAN for offline) for web displayAlgorithms to extract information from histograms for DB storage
Calculation and DB storage of online and offline DQ flags tested (Nov-Dec 2009)
Provided documentation on ATLAS and ATLAS Operations twiki’s

Summary
5
All aspects of CSC Data Quality functional Tested at P1/Tier0 during cosmic /collision runs Work in progress on how to best use the DQ
info in reconstruction Need more shift experience in combined runs Modify/ improve and maintain software, shifter
histograms, documentation on regular basis (as we gain experience)

To Do
6
There are two areas where we need improvement
Online monitoring using the calibration stream Perhaps there is a gain in statistics over the current
GNAM monitoring Software for calibration stream exists but needs to be
tested and integrated at Point 1 Monitoring / rootuple production at the calibration
centers For CSC, these are useful for reconstruction studies
rather than calibration Again, some software for monitoring and rootuple
production exists but needs to be tested and the loop closed
