• Purpose Online monitoring of the performance
  of triggers at various levels
• Access trigger objects in the event and plot
  physics quantities of interest.
• So far, Detector Examines, Physics Examine,
  Root-GUI, .. had been the priority. Have
  recently begun to think about Trigger Examine.
• What Exists Now
• L1CalExamine
• L1MuoExamine
• L1TrkExamine (?)
• L2 Examine

General Plan

• Try to use the Analyze packages directly or use
  as much code from them as possible
• Use ExamineMgr (with possibly some modifications
  to NtupleMgr) to combine many packages to build a
  Global Trigger Examine
• Input and help needed!

• More discussions at the Online Monitoring
• Meetings
• This week on Thursday at 100 pm
• in the Comitium
