Em 15 de setembro de 2026, todos os ambientes do Cloud Composer 1 e da versão 2.0.x do Cloud Composer 2 vão atingir o fim da vida útil planejado e não poderão mais ser usados. Recomendamos planejar a migração para o Cloud Composer 3.
Esta página explica como receber informações sobre DAGs no seu ambiente.
Formas de conferir informações sobre DAGs
O Cloud Composer oferece várias maneiras de receber informações detalhadas sobre DAGs no seu ambiente:
A interface do DAG é uma seção da Google Cloud interface do console do
Cloud Composer dedicada a visualizar e monitorar DAGs, execuções de DAG
e tarefas individuais.
A CLI do Airflow é a interface de linha de comando do Airflow. É possível
receber informações sobre DAGs executando comandos da CLI do Airflow com
gcloud.
Sobre a interface do DAG do Cloud Composer
A interface do DAG é uma seção da Google Cloud interface do console do
Cloud Composer dedicada a visualizar e monitorar DAGs, execuções de DAG
e tarefas individuais.
Na interface da DAG, é possível:
Confira uma lista de DAGs no seu ambiente, incluindo intervalos de programação, estados
de DAG e descrições.
Confira os detalhes da execução do DAG, incluindo execuções bem-sucedidas, ativas e com falhas, o tempo
desde a última execução concluída. Para cada DAG, é possível conferir o histórico de execuções
e instâncias de tarefas associadas a esse DAG específico, incluindo registros
de tarefas executadas.
Filtrar detalhes de execução de DAG. Por exemplo, você pode escolher um intervalo de tempo e
criar consultas para selecionar as informações necessárias.
Confira informações detalhadas sobre DAGs e tarefas individuais. Isso inclui
diagramas DAG visualizados, informações sobre as tarefas em um DAG, o código-fonte
do DAG e informações extras sobre DAGs.
Antes de começar
Verifique se a conta tem uma função que pode acessar a interface do DAG e conferir os detalhes. Para mais informações, consulte Controle de acesso.
A interface de usuário de DAGs é compatível com o Cloud Composer 2.0.1 e versões
posteriores.
Conferir a lista de DAGs do ambiente
Console
A guia DAGs do ambiente mostra a lista de DAGs e os detalhes da execução de cada um deles.
Para conferir a lista de DAGs:
No console Google Cloud , acesse a página Ambientes.
Na coluna Lista de DAGs, siga o link DAGs do seu ambiente.
É possível usar filtros para conferir os detalhes apenas de determinados DAGs ou de
condições específicas. Exemplo:
Selecione o campo Filtros.
Na lista suspensa, 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 por IDs de DAG.
(Opcional) Para filtrar outras condições, adicione outras propriedades no campo Filtros. Por exemplo, é possível filtrar DAGs com execuções
falhadas especificando Failed runs:>0.
IU do Airflow
Para conferir a lista de DAGs na interface da Web do Airflow:
No console Google Cloud , acesse a página Ambientes.
Na coluna Lista de DAGs, siga o link DAGs do seu ambiente.
Selecione um DAG.
Na página Detalhes do DAG, acesse a guia Execuções.
Selecione uma execução de DAG na lista para conferir os detalhes dela, como o
estado das instâncias de tarefas, o número de tentativas e a
duração da execução. É possível selecionar tarefas individuais para conferir
os registros de instância de tarefa.
IU do Airflow
Para conferir a lista de DAGs na interface da Web do Airflow:
No console Google Cloud , acesse a página Ambientes.
Na coluna Servidor da Web do Airflow, siga o link Airflow do
ambiente.
Faça login com a Conta do Google que tem as permissões apropriadas.
Na interface da Web do Airflow, no menu, selecione
Browse>DAG Runs. A página DAG Runs mostra as execuções de DAG do seu ambiente. É possível clicar no link na coluna ID da execução para conferir mais informações sobre as tarefas.
gcloud
Execute o comando dags list-runs da CLI do Airflow:
Na coluna Servidor da Web do Airflow, siga o link Airflow do
ambiente.

You can get information about DAGs by running Airflow CLI commands with `gcloud`.\n\nAbout Cloud Composer DAG UI\n---------------------------\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-2/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\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-2/access-control).\n\n- DAG UI is supported in Cloud Composer 2.0.1 and later\n versions.\n\n\n View the list of DAGs for your environment\n ------------------------------------------\n\n ### Console\n\n The **DAGs** tab of your environment shows the list of DAGs along with DAG\n run details for each DAG.\n\n To view the list of DAGs:\n 1.
