Error Tracking
===============

Airflow can be set up to send errors to `Sentry <https://docs.sentry.io/>`__.

Setup
------

First you must install sentry requirement:

.. code-block:: bash

   pip install 'apache-airflow[sentry]'

After that, you need to enable the integration by set ``sentry_on`` option in ``[sentry]`` section to ``"True"``.

Add your ``SENTRY_DSN`` to your configuration file e.g. ``airflow.cfg`` in ``[sentry]`` section. Its template resembles the following: ``'{PROTOCOL}://{PUBLIC_KEY}@{HOST}/{PROJECT_ID}'``

.. code-block:: ini

    [sentry]
    sentry_dsn = http://foo@sentry.io/123

.. note::
    If this value is not provided, the SDK will try to read it from the ``SENTRY_DSN`` environment variable.

You can supply `additional configuration options <https://docs.sentry.io/error-reporting/configuration/?platform=python>`__ based on the Python platform via ``[sentry]`` section.
Unsupported options: ``integrations``, ``in_app_include``, ``in_app_exclude``, ``ignore_errors``, ``before_breadcrumb``, ``before_send``, ``transport``.
