xAOD monitoring


Finally we are in position to get information from most of the analysis code run. These are some of the questions we want to answer:
  • Which data formats are used for analysis?
  • Which branches are used?
  • Difference between on-grid/off-grid?
  • Which versions of ROOT are used?
  • Measure IO (read) performance

Data collection

  • accessedFiles - full path for all the files in the job
  • accessedBranches - for each branch that was accessed a number of accesses/events
  • accessedContainers - for each container that was accessed a number of accesses/events
  • ReadCalls
  • ReadSize
  • CacheSize
  • pandaID, taskID - if grid job

Data flow


Please use the official git repository.
