The VeloDataMonitor packages

The VeloDataMonitor packages consists of VeloTrackDataMonitor and VeloClusterDataMonitor. They are not real time monitoring algorithms but require input from a data file.

  • VeloClusterDataMonitor produces histograms from the zero-suppressed cluster bank.

  • VeloTrackDataMonitor produces histograms using Tracks from the Velo pattern recognition.

These packages are primarily intended for use during the VELO testbeam and commissioning phase.

The installation procedure is identical for the two packages. Let's install VeloClustersDataMonitor:

  1. Go to your cmt directory
    cd ~/cmtuser
  2. Set the LHCb environment
    LHCbEnv v20r0 (or whatever version you prefer)
  3. Get the latest version from CVS:
    getpack Velo/VeloClusterDataMonitor (select the head version for the latest)
  4. Compile your new package:
    cd Velo/VeloClusterDataMonitor/v*/cmt
    cmt config
    source setup.csh
    5. If everything is OK, the program should now compile without complaints. You have installed VeloClusterDataMonitor! Do the same for VeloTrackDataMonitor.

OK, now we want to run the algorithm from somewhere, for example Brunel or Vetra. I will use Brunel in this example. I assume that you have Brunel installed.
  1. Make sure that the Brunel environment is set using BrunelEnv.
  2. Edit the Brunel requirements file:
    cd $BRUNELROOT/cmt
    emacs requirements
  3. Add the line
    use VeloClusterDataMonitor v* Velo -no_auto_imports (add a second line with VeloTrackDataMonitor if you want to install that too)
  4. Save the file, exit the editor and type
    source setup.csh (if you don't get any error messages here that means you're doing just fine) make
  5. Brunel will now recompile with VeloClusterDataMonitor (and VeloTrackDataMonitor if you added it in step 3)
  6. If everything works you can now put this monitoring options file in your options directory, and include it from your main options file.

That should be it! More documentation on how to use the monitoring will come soon.
