写入气流日志 [英] Writing to Airflow Logs

问题描述

写到Airflow中日志的一种方法是从PythonOperator返回一个字符串，如第44行此处。

One way to write to the logs in Airflow is to return a string from a PythonOperator like on line 44 here.

还有其他方法可以让我写入气流日志文件吗？我发现打印语句没有保存到日志中。

Are there other ways that allow me to write to the airflow log files? I've found that print statements are not saved to the logs.

推荐答案

您可以将日志记录模块导入代码并编写以这种方式记录

You can import the logging module into your code and write to logs that way

import logging

logging.info('Hello')

还有更多选择

import logging    

logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical message')
