Is it possible to customize the format that Airflow uses for logging?

I tried adding a LOG_FORMAT variable in $AIRFLOW_HOME/airflow.cfg, but it doesn't seem to take effect

LOG_FORMAT = "%(asctime)s logLevel=%(levelname)s logger=%(name)s - %(message)s"

You need to change the settings.py file in the airflow package to change the log format

• Update settings.py (after LOGGING_LEVEL add below line):

  LOG_FORMAT = os.path.expanduser(conf.get('core', 'LOG_FORMAT'))

• Update airflow.cfg configuration file: Add line under [core]:

  LOG_FORMAT = "%(asctime)s logLevel=%(levelname)s logger=%(name)s - %(message)s"

• Restart webserver and scheduler services

  Try the approach as mentioned in the answer here to change logging level
