February 07, 2002Online Monitoring Meeting

Detector ExaminesShould aid in:1. Diagnosing problems early and getting it fixed2. 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 fromshifters.• 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.

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 *

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.

• Need list of problems for categorizing the system/data to be “bad” or “maybe”

Examples:

Detector “bad”: Bad/missing module/sector/crateDetector readout problemsHV set wrongUnnoticed HV tripLots of “hot” or “dead” channelsEtc.

Detector “maybe”: Several new hot cellsProblem with a few channelsMagnet current fluctuatingEtc.

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.
