"ATLAS tile calorimeter data quality assessment with commissioning data", 2008

ATLAS Tile Calorimeter measures energy deposits of hadrons and jets.
Trigger and Data AcQuisition system - TDAQ
ATLAS offline reconstruction software - Athena.
Online DQ tools - detector verification tests and online monitoring tools. Feedback within minutes.

Spies on data flow and monitors before data enters event builders and after full event has been built.
Online histogram presenter - OHP - browse available histograms.
Offline DQ tools - analysis, bulk reconstruction and monitoring, automatic histogram checking. Feedback within hours.
Athena TileMonitoring - produce detailed and summary histograms.
Data Quality Monitoring Framework (DQMF)
Apply algorithms to histograms to get DQ result (good, bad, investigate)
Web interface for shifters (WIS) - access DQMF results and plots images.
Graphic representation of detector.

"TileCal web system for DQ analysis", slides, 2009

Web interface for shifters (WIS) - run information, name, type, date, setup.
TileComm analysis - charts/histograms, status at module level, view PNG or PS plots.
DQM viewer - data quality monitoring results, and run parameters.
Monitoring and calibration web system (MCWS) - view module/channel (good/bad) information, generate plots and reports.

Near real-time monitoring of reconstructed offline data.
DQM
han - histogram analyzer

Takes configuration + ROOT file with histograms and runs automatic checks.
Axes ranges, linear/log scales specifies in han configuration.
Outputs ROOT file with checked histograms, status and results, configuration.

handi - han display

Renders han output files as HTML pages - histogram, status, algorithm results.

ATLAS conditions database

Python, C++ or web browsing

XML-RPC web service

han output files e.g. status, results, histogram PNG, histogram via ROOT's XML serialization.
