To produce logs of this format, use the format string below with the python logging moddule.
When piping directly to lnav, make sure to force the logger to use sys.stdout
import sys
import logging
FORMAT = '[%(asctime)s] %(levelname)s %(name)s - %(message)s'
logging.basicConfig(format=FORMAT, stream=sys.stdout)
