alkismavridis opened a new issue, #70968:
URL: https://github.com/apache/airflow/issues/70968
### Under which category would you file this issue?
Airflow Core
### Apache Airflow version
3.3.0
### What happened and how to reproduce it?
## Goal
Completely disable file-based logs from dag processor.
## Context
I Run airflow. I Notice that dag_processor creates many logs under
`/opt/airflow/logs/dag_processor`. In fact, this directory eventually grows
multiple GBs large and eats all available space.
I can create some log rotator / archiver, but in fact I do not need the
`dag_processor` logs at all so **I would very much prefer to deactivate them
completely**.
## What I tried
1. Setting `[logging] --> dag_processor_log_target = stdout` and restarted
airflow. Intuitively I would expect that this would work, but unfortunately the
directory still being created and filled with multiple MBs per day.
A sample from the files I see:
