Cloud Composer는 관리 활동 로그와 같은 감사 로그를 생성합니다. 자세한 내용은 감사 로그 보기를 참고하세요.
시작하기 전에
Google 계정에 환경 버킷의 객체를 볼 수 있는 역할이 있어야 합니다. 자세한 내용은 액세스 제어를 참조하세요.
환경 버킷에 저장된 로그는 버킷의 정책을 사용합니다.
Cloud Composer는 데이터를 영구적으로 보관하는 기본 정책으로 버킷을 만듭니다. Cloud Logging에 저장된 로그의 경우 Cloud Composer는 _Default 및 사용자 정의 로그 보관 기간을 사용합니다.
데이터 손실 방지를 위해 환경의 버킷에 저장된 로그는 환경이 삭제된 후에도 삭제되지 않습니다. 사용자 환경의 버킷에서 로그를 수동으로 삭제해야 합니다.

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\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-------------------\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. Go to the **Logs** tab.\n\nView streaming logs in Cloud Logging\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, locate your environment.\n\n3. in the **Logs** column, click the **Logs** link.\n\nView Airflow task logs in the environment's bucket\n--------------------------------------------------\n\n| **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\n### Console\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\n- [Monitor environments](/composer/docs/composer-2/monitor-environments)\n- [Cloud Composer audit logging](/composer/docs/composer-2/audit-logging)"]]
