"""
HTTP Logstash engine
==========================

An engine that reads messages from the salt event bus and pushes
them onto a logstash endpoint via HTTP requests.

.. versionchanged:: 2018.3.0

.. note::
    By default, this engine take everything from the Salt bus and exports into
    Logstash.
    For a better selection of the events that you want to publish, you can use
    the ``tags`` and ``funs`` options.

:configuration: Example configuration

.. code-block:: yaml

          - http_logstash:
              url: http://blabla.com/salt-stuff
