python+logging+yaml实现日志分割

本文实例为大家分享了python+logging+yaml实现日志分割的具体代码，供大家参考，具体内容如下

1、建立log.yaml文件

version: 1
disable_existing_loggers: False
formatters:
 simple:
  format: "%(asctime)s - %(filename)s - %(levelname)s - %(message)s"
  datefmt: '%F %T'
 
handlers:
 console:
  class: logging.StreamHandler
  level: DEBUG
  formatter: simple
  stream: ext://sys.stdout
 info_file_handler:
  class: logging.handlers.TimedRotatingFileHandler
  level: DEBUG
  formatter: simple
  filename: ./mylog/log.log #这个路径根据自己的日志存放路径填写
  interval: 1
  backupCount: 2 #most 2 extensions
  encoding: utf8
  when: H #这里是按小时生成
root:
 level: INFO
 handlers: [console, info_file_handler]

2、在自己的app.py中引用log.yaml

import yaml
import logging.config
import os
 
def setup_logging(default_path='log.yaml', default_level=logging.INFO):
 """
 Setup logging configuration
 """
 if os.path.exists("mylog"):
  pass
 else:
  os.mkdir('mylog')
 path = default_path
 if os.path.exists(path):
  with open(path, 'rt') as f:
   config = yaml.load(f.read())
  logging.config.dictConfig(config)
 else:
  logging.basicConfig(level=default_level)
  print('the input path doesn\'t exist')
setup_logging(default_path='./log.yaml')
logger = logging.getLogger()

之后就可以在需要日志的业务节点上使用logger.info或者其他级别输出日志信息
