The following Type: "Zabbix trapper" with "Type of information" Text items are required:

.. code-block:: cfg

    Key: salt.trap.info
    Key: salt.trap.warning
    Key: salt.trap.high

To use the Zabbix returner, append '--return zabbix' to the salt command. ex:

.. code-block:: bash

    salt '*' test.ping --return zabbix
