Python Logging: dictConfig

Question

I am trying to use a config file for configure Python Logging, but also adding handlers after the dict config has been loaded. SO my config file is like

version:         


        

Answer 1

Ohh I figure it out. What I need to do is

formatter =logging.Formatter(log_config_dict['formatters']['plain_formatter']['format'])             
fhandler1.setFormatter(formatter)

So, I need to create a Formatter object.

#!/usr/bin/env python

import logging
import logging.handlers
from logging.config import dictConfig

logger = logging.getLogger(__name__)

DEFAULT_LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
}
def configure_logging(logfile_path):
    """
    Initialize logging defaults for Project.

    :param logfile_path: logfile used to the logfile
    :type logfile_path: string

    This function does:

    - Assign INFO and DEBUG level to logger file handler and console handler

    """
    dictConfig(DEFAULT_LOGGING)

    default_formatter = logging.Formatter(
        "[%(asctime)s] [%(levelname)s] [%(name)s] [%(funcName)s():%(lineno)s] [PID:%(process)d TID:%(thread)d] %(message)s",
        "%d/%m/%Y %H:%M:%S")

    file_handler = logging.handlers.RotatingFileHandler(logfile_path, maxBytes=10485760,backupCount=300, encoding='utf-8')
    file_handler.setLevel(logging.INFO)

    console_handler = logging.StreamHandler()
    console_handler.setLevel(logging.DEBUG)

    file_handler.setFormatter(default_formatter)
    console_handler.setFormatter(default_formatter)

    logging.root.setLevel(logging.DEBUG)
    logging.root.addHandler(file_handler)
    logging.root.addHandler(console_handler)



[31/10/2015 22:00:33] [DEBUG] [yourmodulename] [yourfunction_name():9] [PID:61314 TID:140735248744448] this is logger infomation from hello module

I think config log with function is more convenient.
