A 15 de setembro de 2026, todos os ambientes do Cloud Composer 1 e do Cloud Composer 2 versão 2.0.x vão atingir o fim da vida útil planeado e não vai poder usá-los. Recomendamos que planeie a migração para o Cloud Composer 3.
Esta página explica como obter informações sobre DAGs no seu ambiente.
Formas de ver informações sobre DAGs
O Cloud Composer oferece várias formas de obter informações detalhadas sobre os DAGs no seu ambiente:
A IU do DAG é uma secção da Google Cloud interface da consola para o
Cloud Composer dedicada à visualização e monitorização de DAGs, execuções de DAGs
e tarefas individuais.
A IU do Airflow é a interface Web integrada do Airflow.
A CLI do Airflow é a interface de linhas de comando do Airflow. Pode obter informações sobre DAGs executando comandos da CLI do Airflow com gcloud.
Acerca da IU do DAG do Cloud Composer
A IU do DAG é uma secção da Google Cloud interface da consola para o
Cloud Composer dedicada à visualização e monitorização de DAGs, execuções de DAGs
e tarefas individuais.
Na IU do DAG, pode:
Veja uma lista de DAGs no seu ambiente, incluindo intervalos de agendamento, estados de DAGs e descrições.
Veja os detalhes de execução do DAG, incluindo execuções bem-sucedidas, ativas e com falhas, bem como o tempo
desde a última execução concluída. Para cada DAG, pode ver o histórico de execuções de DAGs e instâncias de tarefas associadas a este DAG específico, incluindo registos de tarefas executadas.
Filtre os detalhes da execução do DAG. Por exemplo, pode escolher um intervalo de tempo e criar consultas para selecionar as informações de que precisa.
Veja informações detalhadas sobre DAGs e tarefas individuais. Isto inclui
diagramas DAG visualizados, informações sobre as tarefas num DAG, código fonte do DAG e informações adicionais sobre DAGs.
Antes de começar
Certifique-se de que a sua conta tem uma função que pode aceder à IU do DAG e ver os detalhes do DAG. Para mais informações, consulte o artigo Controlo de acesso.
Na coluna Lista de DAGs, siga o link DAGs para o seu ambiente.
Pode usar filtros para ver os detalhes apenas de determinados DAGs ou de determinadas condições. Por exemplo:
Selecione o campo Filtros.
Na lista pendente, selecione a propriedade ID do DAG.
Especifique o identificador do DAG. Os resultados mostram detalhes apenas para o DAG selecionado.
(Opcional) Para incluir mais DAGs, adicione operadores OR seguidos dos IDs dos DAGs.
(Opcional) Para filtrar por outras condições, adicione outras propriedades no campo Filtros. Por exemplo, pode filtrar DAGs com execuções com falhas especificando Failed runs:>0.
IU do Airflow
Para ver a lista de DAGs na interface Web do Airflow:
Na Google Cloud consola, aceda à página Ambientes.
Na coluna Lista de DAGs, siga o link DAGs para o seu ambiente.
Selecione um DAG.
Na página Detalhes do DAG, aceda ao separador Execuções.
Selecione uma execução de DAG na lista para ver os detalhes da execução de DAG, como o estado das instâncias de tarefas para esta execução de DAG, o número de tentativas e a duração da execução. Pode selecionar tarefas individuais para ver os registos de instâncias de tarefas.
IU do Airflow
Para ver a lista de DAGs na interface Web do Airflow:
Na Google Cloud consola, aceda à página Ambientes.
Na coluna Servidor Web do Airflow, siga o link do Airflow para o seu ambiente.
Inicie sessão com a Conta Google que tem as autorizações adequadas.
Na interface Web do Airflow, no menu, selecione
Procurar>Execuções de DAGs. A página Execuções de DAG apresenta as execuções de DAG para o seu ambiente. Pode seguir o link na coluna ID da execução
para obter informações adicionais sobre as tarefas.
gcloud
No Airflow 1.10.*, execute o list_dag_runscomando da CLI do Airflow:
Na coluna Servidor Web do Airflow, siga o link do Airflow para o seu ambiente.
Inicie sessão com a Conta Google que tem as autorizações adequadas.
Na interface Web do Airflow, na página DAGs, é apresentada uma lista de DAGs para o seu ambiente.
Para o seu DAG, na coluna Links, siga o link Vista de gráfico.

Consola
Pode ver o código fonte dos seus DAGs e informações adicionais, como identificadores de DAGs e links para ficheiros de definição de DAGs no contentor do ambiente.
Na Google Cloud consola, aceda à página Ambientes.

You can get information about DAGs by running Airflow CLI commands with `gcloud`.\n\nAbout Cloud Composer DAG UI\n\nDAG UI is a section of Google Cloud console interface for\nCloud Composer dedicated to viewing and monitoring DAGs, DAG runs,\nand individual tasks.\n\nIn DAG UI, you can:\n\n- View a list of DAGs in your environment, including schedule intervals, DAG\n states, and descriptions.\n\n- Pause, unpause, and [trigger DAGs](/composer/docs/composer-1/schedule-and-trigger-dags#manual).\n\n- View DAG run details, including successful, active, and failed runs, time\n since the last completed run. For each DAG, you can see the history of DAG\n runs and task instances associated with this particular DAG, including logs\n for executed tasks.\n\n- Filter DAG run details. For example, you can pick a time interval and\n create queries to select the information that you need.\n\n- View detailed information about individual DAGs and tasks. This includes\n visualized DAG diagrams, information about the tasks within a DAG, DAG\n source code, and extra information about DAGs.\n\nBefore you begin\n\n- Make sure that your account has a role that can access DAG UI and view DAG\n details. For more information, see [Access control](/composer/docs/composer-1/access-control).\n\n \u003cbr /\u003e\n\n- DAG UI requires enabled [DAG serialization](/composer/docs/composer-1/dag-serialization).\n\n- DAG UI is supported in Cloud Composer 1.17.8 and later\n versions.\n\nView the list of DAGs for your environment \n\nConsole\n\nThe **DAGs** tab of your environment shows the list of DAGs along with DAG\nrun details for each DAG.\n\nTo view the list of DAGs:\n\n1.

(Optional) To include more DAGs, add `OR` operators followed by DAG ids.\n5. (Optional) To filter on other conditions, add other properties in the **Filters** field. For example, you can filter for DAGs with failed runs by specifying `Failed runs:\u003e0`.\n\nAirflow UI\n\nTo view the list of DAGs in the Airflow web interface:\n\n1.
