Py_logging

이 편은py-logging을 이야기합니다.

로그 수준 크기 관계: CRITICAL > ERROR > WARNING > INFO > DEBUG > NOTSET..

레벨을 INFO로 설정하고 측정을 시작할 때 출력할 때 logging합니다.info('hell0'), 측정 끝에ogging으로 변경.debug(‘hell0’)

0x1.logging.basicConfig(주의#)

0x1.1 콘솔로 내보내기

import logging

logging.basicConfig(
        level = logging.DEBUG,      # INFO                   
        format = '%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s'
        #,filename='myapp.log',
        #filemode='a+'
        )

0x1.2 파일로 내보내기

logging.basicConfig(
        level = logging.DEBUG,      # INFO                   
        format = '%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s'
        ,filename='myapp.log',
        filemode='a+'
        )

0x1.3은 콘솔과 파일에 동시에 출력됩니다.

*： root, .

logging.basicConfig(
        level = logging.DEBUG,      # INFO                   
        format = '%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s'
        #,filename='myapp.log',
        #filemode='a+'
        )

# log . logging ， addHandler 。
formatter = logging.Formatter('%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s')
# 
file_handler= logging.FileHandler('myapp.log','a+')     #FileHandler(filename, mode=’a’, encoding=None, delay=False)
file_handler.setFormatter(formatter)
file_handler.setLevel(logging.DEBUG)
logging.getLogger('').addHandler(file_handler)
## console
#console_handler    = logging.StreamHandler(sys.stdout)
#console_handler.setLevel(logging.DEBUG)
#console_handler.formatter = formatter
#logging.getLogger('').addHandler(console_handler)
