Python记录:dictConfig [英] Python Logging: dictConfig

问题描述

我正在尝试使用配置文件来配置Python日志记录，但是还要在dict配置加载后添加处理程序.所以我的配置文件就像

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: 1
formatters:
  default_formatter:
    format: '%(asctime)s : %(levelname)s : %(message)s'
    datefmt: '%d-%b-%Y %H:%M:%S'
  plain_formatter:
    format: '%(message)s'
handlers:  
  console_default_handler:
    class: logging.StreamHandler
    level: INFO
    formatter: default_formatter
    stream: ext://sys.stdout  
root:
  level: INFO
  handlers: [console_default_handler]

然后在代码中-我知道

log_config_dict=yaml.load(open(log_config_file, 'r'))
logging.config.dictConfig(log_config_dict)

我想以这种方式添加记录器-

And I want to add loggers in this way -

fhandler1=logging.FileHandler(log_file_name,mode="w")
fhandler1.setFormatter(log_config_dict['formatters']['plain_formatter'])
fhandler1.setLevel(logging.DEBUG)

这不起作用.我有什么方法可以捕获在dictConfig中定义的获取值，以便在我的手动日志配置中使用它们?

This is not working. Is there any way I catch fetch values defined in the dictConfig for using them in my manual log configuration please?

谢谢

#!/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

我认为带有功能的配置日志更方便.

I think config log with function is more convenient.
