# The next function parses the Tracer output.
# Here are some differences to consider if you use Tracer output
# instead of the StallMonitor output.
# - The time in the text of the Tracer output is not as precise
# as the StallMonitor (.01 s vs .001 s)
# - The MessageLogger bases the time on when the message printed
# and not when it was initially queued up to print which smears
# the accuracy of the times.
# - Both of the previous things can produce some strange effects
# in the output plots.
# - The file size of the Tracer text file is much larger.
# - The CPU work needed to parse the Tracer files is larger.
# - The Tracer log file is expected to have "++" in the first
# or fifth line. If there are extraneous lines at the beginning
# you have to remove them.
# - The ascii printout out will have one extraneous line
# near the end for the SourceFindEvent start.
# - The only advantage I can see is that you have only
# one output file to handle instead of two, the regular
# log file and the StallMonitor output.
# We might should just delete the Tracer option because it is
# clearly inferior ...

def printHelp():
    s = '''
To Use: Add the StallMonitor Service to the cmsRun job you want to check for
  stream stalls. Use something like this in the configuration:

  process.add_(cms.Service("StallMonitor", fileName = cms.untracked.string("stallMonitor.log")))

  After running the job, execute this script and pass the name of the
  StallMonitor log file to the script.

  By default, the script will then print an 'ASCII art' stall graph
  which consists of a line of text for each time a module or the
  source stops or starts. Each line contains the name of the module
  which either started or stopped running, and the number of modules
  running on each stream at that moment in time. After that will be
  the time and stream number. Then if a module just started, you
  will also see the amount of time the module spent between finishing
  its prefetching and starting.  The state of a module is represented
  by a symbol:

    plus  ("+") the stream has just finished waiting and is starting a module
    minus ("-") the stream just finished running a module

  If a module had to wait more than 0.1 seconds, the end of the line
  will have "STALLED". Startup actions, e.g. reading conditions,
  may affect results for the first few events.

  Using the command line arguments described above you can make the
  program create a PDF file with actual graphs instead of the 'ASCII art'
  output.

  Once the graph is completed, the program outputs the list of modules
  which had the greatest total stall times. The list is sorted by
  total stall time and written in descending order. In addition, the
  list of all stall times for the module is given.

  There is an inferior alternative (an old obsolete way).
  Instead of using the StallMonitor Service, you can use the
  Tracer Service.  Make sure to use the 'printTimestamps' option
  cms.Service("Tracer", printTimestamps = cms.untracked.bool(True))
  There are problems associated with this and it is not recommended.'''
