OfflineErrorAnalysis

Introduction

This page describes how to run script that analyses the events in the debug stream (usually) to obtain a summary of the HLT errors that have occurred in them.

Howto

The scripts are in the directory:
cd ~trigcomm/other_scripts/error_analysis/DebugErrorAnalysisJob
To run the jobs:
  • Make a list of files you want to run on and put it in ~trigcomm/other_scripts/error_analysis/list_of_files. For example (does anyone know a smarter way to do this??) :
     nsls /castor/cern.ch/grid/atlas/DAQ/2008/89740/debug_hlterror/ | gawk '{printf("/castor/cern.ch/grid/atlas/DAQ/2008/89740/debug_hlterror/%s\n",$1)}' > ~/other_scripts/error_analysis/list_of_files/89740-dbg 
  • Submit the jobs, like so:
     cd ~trigcomm/other_scripts/error_analysis/DebugErrorAnalysisJob
    bsub -q atlastrig Analyze_Files_Lxbatch.sh <files_to_analyze> <run_number_prefix> <number_of_files>
    Where the variables mean the following:
    • files_to_analyze: the file with the list of the input files (e.g. 89740-test ). The script will look for this file in ~/other_scripts/error_analysis/list_of_files/
    • run_number_prefix: A that will end up in the output file name. For normal running, just put the run-number.
    • number_of_files: Run over this many files.

The job will produce a root file in ~/other_scripts/error_analysis/RootFiles containing an ntuple describing the errors. The file will be called *run_number_prefix*_error_summary_castor.root.


  • While the root file can be inspected manually, there is also a script to produce web-output. This should be run on voatlas17 in order to have access to the web area:
   ssh lxvoadm      # if not there already, go to voatlas17. We have
   ssh voatlas17    # to go through the lxvoadm gateway for that.
   cd ~trigcomm/other_scripts/error_analysis/DebugErrorAnalysisJob
   makeHTML.sh <RootFile_to_use> <run_number>
With:
  • RootFile_to_use: Full path to the root file, e.g. ../RootFiles/89740-test_error_summary_castor.root.
  • run_number : this is a directory in ../HTMLFiles, eventually moved to /var/www/error_analysis/ with all that is displayed in the webpage. Normally: just use the run_number.

If this was successful, the web-page is now here: http://voatlas17.cern.ch/error_analysis/
