--------------------------------------
Summary: Explain/Improve Default Logging Behaviour
Key: AIRFLOW-5573
URL: https://issues.apache.org/jira/browse/AIRFLOW-5573
Project: Apache Airflow
Issue Type: Improvement
Components: logging
Affects Versions: 1.10.5
Reporter: Raphael Dumas
The [documentation for
logging|[https://airflow.apache.org/howto/write-logs.html]] currently only
mentions the various places logging files can get stored. It does not mention
any configuration options for log persistence (which I'm guessing there are
none).
After 1 month of operation with mostly just the example dags, my log files were
on the order of 20 GB.
I have found found the following resources, indicating this appears to a common
problem:
- [Removing Airflow task logs|https://stackoverflow.com/q/43548744/4047679]
- [Remove Airflow Scheduler
logs|https://stackoverflow.com/questions/49783850/remove-airflow-scheduler-logs]
- Both lead to [this
"extension"|https://github.com/teamclairvoyant/airflow-maintenance-dags] which
includes a dag for deleting log files older than X days.
*Can the default logging behaviour be explained in the logging documentation
section?*
*Can that extension be linked to in the logging documentation section?*
*Can there be a configuration option to specify the amount of time logs will
persist?*
