UI / Screenshots¶

The Airflow UI makes it easy to monitor and troubleshoot your data pipelines. Here’s a quick overview of some of the features and visualizations you can find in the Airflow UI.

DAGs View¶

List of the DAGs in your environment, and a set of shortcuts to useful pages. You can see exactly how many tasks succeeded, failed, or are currently running at a glance. To hide completed tasks set show_recent_stats_for_completed_runs = False

In order to filter DAGs (e.g by team), you can add tags in each dag. The filter is saved in a cookie and can be reset by the reset button. For example:

dag = DAG("dag", tags=["team1", "sql"])

Tree View¶

A tree representation of the DAG that spans across time. If a pipeline is late, you can quickly see where the different steps are and identify the blocking ones.

There is also visual difference between scheduled and manually triggered DAGs/tasks:

The DAGs/tasks with a black border are scheduled runs, whereas the non-bordered DAGs/tasks are manually triggered, i.e. by airflow dags trigger.

Graph View¶

The graph view is perhaps the most comprehensive. Visualize your DAG’s dependencies and their current status for a specific run.

Calendar View¶

The calendar view gives you an overview of your entire DAG’s history over months, or even years. Letting you quickly see trends of the overall success/failure rate of runs over time.

Variable View¶

The variable view allows you to list, create, edit or delete the key-value pair of a variable used during jobs. Value of a variable will be hidden if the key contains any words in (‘password’, ‘secret’, ‘passwd’, ‘authorization’, ‘api_key’, ‘apikey’, ‘access_token’) by default, but can be configured to show in clear-text. See Masking sensitive data.

Gantt Chart¶

The Gantt chart lets you analyse task duration and overlap. You can quickly identify bottlenecks and where the bulk of the time is spent for specific DAG runs.

Task Duration¶

The duration of your different tasks over the past N runs. This view lets you find outliers and quickly understand where the time is spent in your DAG over many runs.

Code View¶

Transparency is everything. While the code for your pipeline is in source control, this is a quick way to get to the code that generates the DAG and provide yet more context.
