On September 15, 2026, all Cloud Composer 1 versions and versions 2.0.x of Cloud Composer 2 will reach their planned end of life. You will not be able to use environments with these versions. We recommend planning migration to Cloud Composer 3. Cloud Composer 2 versions 2.1.x and later are still supported and are not impacted by this change.
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.

As an\n alternative, you can [configure a sink](/logging/docs/export/configure_export_v2) in\n Cloud Logging to route logs to any of the supported locations.\n\n For an example of routing environment logs to a Cloud Storage bucket,\n see\n [Restrict locations for Cloud Composer logs](/composer/docs/composer-3/configure-resource-location-restrictions#restrict-logs-location).\n | **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.\n\n\nView streaming logs\n-------------------\n\nTo view streaming logs in Cloud Logging: \n\n### Console\n\n1. In the Google Cloud console, go to the **Environments** page.\n\n [Go to Environments](https://console.cloud.google.com/composer/environments)\n2. In the list of environments, click the name of your environment.\n The **Environment details** page opens.\n\n3.
