Its configuration options can be overridden with the GUNICORN_CMD_ARGS env variable. You must ensure that the key matches so that communication can take place without problems. Defaults are 87, respectively.Ĭommunication between the webserver and the worker is signed with the key specified by secret_key option in section. The server is running on the port specified by worker_log_server_port option in section, and option triggerer_log_server_port for triggerer. In triggerer, logs are served unless the service is started with option -skip-serve-logs. If CeleryExecutor is used, then when airflow worker is running. If SequentialExecutor or LocalExecutor is used, then when airflow scheduler is running. In order to view logs in real time, Airflow starts an HTTP server to serve the logs in the following cases: Most task handlers send logs upon completion of a task. Serving logs from workers and triggerer ¶ This is the usual way loggers are used directly in Python code: Use the standard logger approach of creating a logger using the Python module name Use standard print statements to print to stdout (not recommended, but in some cases it can be useful) Log with the self.log logger from BaseOperator

So if you want to log to the task log from custom code of yours you can do any of the following: Propagates logging to the root will also write to the task log. But also due to the root logger handling, any standard logger (using default settings) that This logger is created and configured by LoggingMixin that all Have a log logger that you can use to write to the task log.
