Online Data Monitoring

What we want to know

  • Are the detectors working?
    • Do all of the channels have hits?
    • What are the hit rates per channel?
    • Are the energies & times OK or garbage (by channel)?

Example

Action Items

  • David is updating RootSpy and the documentation.
  • When he's finished, he'll contact the different detector groups and have them write their monitoring plugins.
  • We need to stay in contact with those groups, and make sure that they:
    • Write the plugins
    • Integrate them into RootSpy (visualization macros?)
    • Are histogramming the data we want (see above)

Offline Data Monitoring

What we want to know

  • Can we reproduce the online histograms offline:
    • Can we ready data from tape?
    • Are all the channels present?
    • Are all the recorded values within the expected ranges?
  • How do the online histograms change as a function of time (e.g. hits/event vs run number)?
  • Calibration status/quality histograms (run-by-run
  • Reconstruction status/quality histograms
  • Analysis histograms
    • Can we see pi0, etc. peaks,

Action Items

  • Make cron-job scripts that automatically read data from disk and make histograms of the above.
  • Make cron-job scripts for visualizing the data:
    • Make it easy to view today's & yesterday's online data (webpage?)
    • Make it easy to view the status of things as a function of time (webpage?)
