Metrics
|
|
=======
|
|
|
|
Airflow can be set up to send metrics to `StatsD <https://github.com/etsy/statsd>`__.
|
|
|
|
Setup
|
|
-----
|
|
|
|
First you must install statsd requirement:
|
|
|
|
.. code-block:: bash
|
|
|
|
pip install 'apache-airflow[statsd]'
|
|
|
|
Add the following lines to your configuration file e.g. ``airflow.cfg``
|
|
|
|
.. code-block:: ini
|
|
|
|
[scheduler]
|
|
statsd_on = True
|
|
statsd_host = localhost
|
|
statsd_port = 8125
|
|
statsd_prefix = airflow
|
|
|
|
If you want to avoid send all the available metrics to StatsD, you can configure an allow list of prefixes to send only
|
|
the metrics that start with the elements of the list:
|
|
|
|
.. code-block:: ini
|
|
|
|
[scheduler]
|
|
statsd_allow_list = scheduler,executor,dagrun
|
|
