I forgot to mention that you can use the Python log facility to write to STDOUT and a file. This gives you several good opportunities. in regard to real-time log inspection (tailing the file) and enabling or disabling debug logs as required.
Below a code example.
import logging
logFile = '/tmp/'+ emc_vars['workflowName'].replace(' ', '_') +'_'+ time.strftime("%Y-%m-%d_%H-%M-%S") +'.log'
log = None
########################################################################
def setupLogger():
global log
log = logging.getLogger()
log.setLevel( logging.DEBUG )
screen = logging.StreamHandler()
screen.setLevel( logging.INFO )
screen_formatter = logging.Formatter('%(asctime)s.%(msecs)03d %(levelname)-7s %(message)s', datefmt='%H:%M:%S')
screen.setFormatter( screen_formatter )
log.addHandler( screen )
if emc_vars['DEBUG'].lower() == 'true':
log.info("write LOG file " + logFile)
file = logging.FileHandler(logFile, mode='a', encoding='utf-8')
file.setLevel( logging.DEBUG )
formatter = logging.Formatter('%(asctime)s %(levelname)-7s [%(filename)s:%(lineno)d] %(message)s')
file.setFormatter( formatter )
log.addHandler( file )
########################################################################
def main():
setupLogger()
log.info("Hello World!")
########################################################################
main()
