python的log文件回滚

 

python生成按照文件大小进行回滚的日志

 

import logging
import logging.handlers as handlers

log_file_path = r'/Users/kanpiaoxue/tmp/20200518/log/hello.log'
log_file_max_bytes = 1024 * 1
log_file_max_count = 10
log_file_level= logging.DEBUG

log_formatter = logging.Formatter('%(asctime)s [PID:%(process)d] [%(threadName)-12.12s] %(levelname)-5.5s [%(filename)s:%(lineno)d] --> %(message)s')
log_handler = handlers.RotatingFileHandler(log_file_path, maxBytes=log_file_max_bytes, backupCount=log_file_max_count)
log_handler.setFormatter(log_formatter)

logger = logging.getLogger(__name__)
logger.setLevel(log_file_level)
logger.addHandler(log_handler)


def test_001():
    while True:
        logger.debug('start to test_001')
        logger.info('start to test_001')
        print 'start to test_001'
    pass


if __name__ == '__main__':
    test_001()
    pass
