Le 15 septembre 2026, tous les environnements Cloud Composer 1 et Cloud Composer 2 version 2.0.x atteindront leur fin de vie prévue et vous ne pourrez plus les utiliser. Nous vous recommandons de planifier la migration vers Cloud Composer 3.
Cette page explique comment accéder aux journaux Apache Airflow pour Cloud Composer et les afficher.
À propos des types de journaux
Cloud Composer inclut les journaux Airflow suivants :
Journaux de streaming Ces journaux contiennent les journaux des tâches Airflow, ainsi que les journaux des composants Airflow de votre environnement, tels que les programmeurs et les nœuds de calcul Airflow.
Pour en savoir plus sur Cloud Logging et Cloud Monitoring pour votre environnement Cloud Composer, consultez la section Surveiller des environnements.
Votre compte Google doit disposer d'un rôle permettant d'afficher des objets dans des buckets d'environnement. Pour plus d'informations, consultez la section Contrôle des accès.
Les journaux stockés dans le bucket de l'environnement utilisent la règle du bucket.
Cloud Composer crée des buckets avec la règle par défaut qui conserve les données indéfiniment. Pour les journaux stockés dans Cloud Logging, Cloud Composer utilise les périodes de conservation des journaux_Default et définies par l'utilisateur.
Pour éviter toute perte de données, les journaux enregistrés dans le bucket de l'environnement ne sont pas supprimés après la suppression de votre environnement. Vous devez supprimer manuellement les journaux du bucket de votre environnement.
Afficher les journaux de streaming
Pour afficher les journaux de streaming dans Cloud Logging :
Console
Dans la console Google Cloud , accédez à la page Environnements.
Dans la liste des environnements, recherchez une ligne portant le nom de votre environnement, puis cliquez sur le lien DAG dans la colonne Dossier des DAG. La page Informations sur le bucket s'ouvre.
Dans le volet Navigateur de dossiers, cliquez sur /logs.

These logs contain Airflow task logs, as well\n as logs of Airflow components of your environment, such as Airflow\n schedulers and workers.\n\n To learn about Cloud Logging and Cloud Monitoring for your\n Cloud Composer environment, see\n [Monitor environments](/composer/docs/composer-2/monitor-environments).\n- [Airflow task logs in the environment's bucket](#view-bucket). These logs are\n associated with single DAG tasks.\n\n If you\n [enable saving logs to the environment's bucket](/composer/docs/composer-2/enable-saving-logs-to-environment-bucket),\n Cloud Composer saves files with Airflow task logs to the `/logs`\n folder.\n\n- Cloud Composer generates [audit logs](/logging/docs/audit), such as Admin\n Activity logs. For more information, see\n [View audit logs](/composer/docs/composer-2/audit-logging).\n\nBefore you begin\n\n\u003cbr /\u003e\n\n- Your Google Account must have a role that can view objects in environment\n buckets. For more information, see [Access control](/composer/docs/composer-2/access-control).\n\n- Logs stored in environment's bucket use the policy of the bucket.\n Cloud Composer creates buckets with the default policy that keeps\n data forever. For logs stored in Cloud Logging,\n Cloud Composer uses `_Default` and User-defined\n [logs retention periods](/logging/quotas#logs_retention_periods).\n\n- To prevent data loss, logs saved in environment's bucket\n **are not deleted after you delete your environment**. You must manually\n delete logs from your environment's bucket.\n\nView streaming logs\n\nTo view streaming logs in Cloud Logging: \n\nConsole\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. Go to the **Logs** tab.\n\nView streaming logs in Cloud Logging\n\nTo view streaming logs in Cloud Logging: \n\nConsole\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, locate your environment.\n\n3. in the **Logs** column, click the **Logs** link.\n\nView Airflow task logs in the environment's bucket **Note:** You can view Airflow task logs [in the Airflow UI](/composer/docs/composer-2/access-airflow-web-interface).\n\nTo view Airflow task logs in your environment's bucket: \n\nConsole\n\n1. In 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, find a row with the name of your environment\n and in the **DAGs folder** column click the **DAGs** link. The\n **Bucket details** page opens.\n\n3. In the **Folder browser** pane, click `/logs`.\n\n | **Note:** If this folder is empty, then [saving logs to the environment's bucket](/composer/docs/composer-2/enable-saving-logs-to-environment-bucket) might be disabled for your environment.\n\nWhat's next\n\n- [Monitor environments](/composer/docs/composer-2/monitor-environments)\n- [Cloud Composer audit logging](/composer/docs/composer-2/audit-logging)"]]
