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.

|

|
|
|
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.
|
|
|

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

|
|
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.

|
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.

Task Instance Context Menu
|
|
..........................
|
|
From the pages seen above (tree view, graph view, gantt, ...), it is always
|
|
possible to click on a task instance, and get to this rich context menu
|
|
that can take you to more detailed metadata, and perform some actions.
