• February 07, 2002
• Online Monitoring Meeting
• Detector Examines
• Should aid in
• Diagnosing problems early and getting it fixed
• Making decisions on the detector status and data
  quality
• Goals for the Presentations on Examines
• Have experts take a good look at the Examines
  get feedback from
• shifters.
• Identify and implement improvement.
• Ensure that shifters have proper tools and clear
  instructions to do their job.
• Should the training be more rigorous?
• Develop a set of summary histograms for global
  monitoring.
• Develop criteria for run certification.

2

• Other Issues
• Physics Examine
• Michiel is making progress
• We will use as much code as possible from
  offline DQM effort for physics histograms
  (Stefan, Arnulf, etc.)
• Issues of I/O for Physics Examine, Express
  Stream, Event Display, Begin End Run, and Run
  Certification interface are looked into.
• Need Input
• Releases (code) used for Examines?
• Online resources for monitoring?
• We will discuss these at a future meeting

3

• GUI
• Histoscope
• CDs policy is to continue maintenance, but no
  development unless requested by experiments.
• Joy is willing to come to our meeting to answer
  questions.
• Root
• Lots of emails back forth between Joel and
  Harrison. Constructive open dialogue.
• Harrison has contacted Rene Brun, downloaded a
  version of ROOT browser which he says works
  remarkably well. Not all functions as Joels.
• We will have a meeting on GUI next week Time
  Place TBA.

4

• Need list of problems for categorizing the
  system/data to be bad or maybe
• Examples
• Detector bad Bad/missing module/sector/crate
• Detector readout problems
• HV set wrong
• Unnoticed HV trip
• Lots of hot or dead channels
• Etc.
• Detector maybe Several new hot cells
• Problem with a few channels
• Magnet current fluctuating
• Etc.

5

• Please send me
• An electronic file of your presentation.
• And other input where required.
• Keep me informed (cc me on your mail) about
  online detector data quality monitoring issues.
