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)?
- Is the reconstruction working?: Run full reconstruction over a small % of data, view tracking/shower-reconstruction results online (hdview2, monitoring_hists plugins).
Example
- CDC_online plugin (Naomi): Trunk Link
- Instructions for Online Monitoring plugins
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)
- Paul will write scripts so that the results of the monitoring_hists plugin are viewable in RootSpy.
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 (individual runs & a function of time)
- Reconstruction status/quality histograms
- Num tracks, showers, hits, etc.
- Reconstructed track kinematics
- Track / detector-hit matching
- PID Quality
- Analysis histograms
- Can we see pi0 peaks
- Can we see simple final states
- proton pi+ pi-
- proton pi+ pi- pi0
- proton pi+ pi- eta
Action Items
- Make sure that the detector groups make plugins for doing the calibrations and viewing the quality/results.
- 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 data from any given run (webpage?)
- Make it easy to view the status of things as a function of time (webpage?)
