Filters ( logging.Filter): Determine which log records are emitted.13 Airflow + python logging module doesnt write to log file. Container scheduler was using 14386916Ki, which exceeds its request of 0. When I run a describe on the pod, the issue is because The node was low on resource: ephemeral-storage.

Restart the Airflow webserver and scheduler, and trigger (or wait for) a new task execution.Send logs to an S3 bucket using the Astro CLI.When and how to configure logging settings.How to add custom task logs from within a DAG.Where to find logs for different Airflow components.In this guide, you'll learn the basics of Airflow logging, including: You can export these logs to a local file, your console, or to a specific remote storage solution.
