View Airflow logs

Cloud Composer 3 | Cloud Composer 2 | Cloud Composer 1

This page describes how to access and view Apache Airflow logs for Cloud Composer.

About log types

Cloud Composer has the following Airflow logs:

• Streaming logs. These logs contain Airflow task logs, as well as logs of Airflow components of your environment, such as Airflow schedulers and workers.

  To learn about Cloud Logging and Cloud Monitoring for your Cloud Composer environment, see Monitor environments.

• Cloud Composer generates audit logs, such as Admin Activity logs. For more information, see View audit logs.

Before you begin

• Cloud Composer 3 environments don't save Airflow task logs to the environment's bucket. As an alternative, you can configure a sink in Cloud Logging to route logs to any of the supported locations.

  For an example of routing environment logs to a Cloud Storage bucket, see Restrict locations for Cloud Composer logs.

  Important: If you use a sink to route logs, we recommend to keep environment logs in Cloud Logging as well as in the configured location. If you use the provided example, skip the last step and don't add an exclusion for Cloud Logging.
