How to setup logger for GUnicorn?

[epicGeek]

• logzero version: 1.5.0
• Python version: 2.7.14
• Operating System: Debian

Description

I am running a flask app behind a gunicorn in a docker container.
But I have no idea how to make logzero to get the gunicorn log in the log file

What I Did

Here is my code:

def get_logger():
    from spa_manager import spa_config
    logger_format = spa_config["LOGGER_FORMAT"]
    logger_abs_path = spa_config["LOGGER_ABS_PATH"]
    logzero.logfile(logger_abs_path, maxBytes=5*1024*1024, backupCount=10)
 # I setup sqlalchemy logger to record SQL info. It works.
    logzero.setup_logger(name="sqlalchemy.engine", logfile=logger_abs_path, formatter=logging.Formatter(spa_config["LOGGER_FORMAT"]))
# Here I tried to setup gunicorn log , not work.
    logzero.setup_logger(name="gunicorn.error", logfile=logger_abs_path, formatter=logging.Formatter(spa_config["LOGGER_FORMAT"]))
    formatter = logging.Formatter(logger_format)
    logzero.formatter(formatter)
    return logger
