View metrics for DAGs
The DAGs page in the Cloud UI lets you view and manage each DAG running on your Workspace, as well as find detailed information about your DAG and its code. These summary and detailed metrics allow you to see information such as the outcomes of your DAG runs and DAG's code. You can use this to check your DAG's performance, debug issues in your DAG code and schedule, and confirm your DAG alerts have been configured correctly.
To access the DAGs page, you can either click DAGs on your sidebar or click View DAGs on a Deployment's information page.
DAGs overview
The DAGs page shows the following summary information about the DAGs for all Deployments in your Workspace. You can filter through these DAGs using the left menu:
Total DAG runs over the last 14 days, expressed as a bar chart.
Each bar in the chart represents an individual DAG run. A bar's color represents whether the DAG run was a success or a failure, while its length represents the total duration of the DAG run. If there are more than 14 DAG runs in the last 14 days, then the chart shows only the 14 most recent DAG runs.
State: Indicates whether the DAG is Active or Paused. If a DAG has a purple lightning symbol next to its name, that DAG is Active.
Last Run: The duration of the last DAG run and the ending time of the DAG's most recent DAG run, expressed relative to the current time.
Schedule: The frequency that the DAG runs and the starting time of the next DAG run, expressed relative to the current time.
Deployment: The Deployment ID of the Deployment for the current DAG Run.
Owner(s): The Airflow DAG owner attribute. You can change the owner attribute when you write or update your DAG.
Tags: The custom tags that you marked your DAG with. To add custom tags to a DAG, see Airflow documentation.
View detailed metrics for a DAG
To view more detailed information about a specific DAG, you can either Open in Airflow or select the DAG to manage it from the Cloud UI. After you open the detailed view of a specific DAG, you can find both the same summary metrics visible on the DAGs overview page and detailed views of the DAG bar chart, graph, and code.
