   I think this is already possible by setting the log level of the root logger. To do so, follow the [Advanced Configuration guide](https://airflow.apache.org/docs/apache-airflow/stable/logging-monitoring/logging-tasks.html#advanced-configuration).
   
   * [`logging.debug`](https://github.com/apache/airflow/blob/fc0fb22c120a7c12426ecaf6254159e7daf2de9e/airflow/settings.py#L442) logs to the root logger
   * The log level for the [root logger](https://github.com/apache/airflow/blob/fc0fb22c120a7c12426ecaf6254159e7daf2de9e/airflow/config_templates/airflow_local_settings.py#L114) is configured in the [`DEFAULT_LOGGING_CONFIG` variable](https://github.com/apache/airflow/blob/fc0fb22c120a7c12426ecaf6254159e7daf2de9e/airflow/config_templates/airflow_local_settings.py#L57) of `airflow_local_settings.py`
   * The log level for the root logger is configured in `airflow.cfg`, so ensure you have a `logging` section and a `LOGGING_LEVEL` variable:
     ```ini
     LOGGING_LEVEL = info
     ```

   @halilduygulu Can you try out the above and see if that works for you? If so, this issue can be closed.
