Presentation Transcript

  1. February 07, 2002 • OnlineMonitoringMeeting • DetectorExamines • Should aid in: • Diagnosing problems early and getting it fixed • Making decisions on the detector status and data quality • GoalsforthePresentationsonExamines: • 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. OtherIssues • 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. • NeedInput: • Releases (code) used for Examines? • Online resources for monitoring? • * We will discuss these at a future meeting *

  3. GUI • Histoscope: • CD’s 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 Joel’s. • 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.
