Display return data in JSON format
==================================

:configuration: The output format can be configured in two ways:
    Using the ``--out-indent`` CLI flag and specifying a positive integer or a
    negative integer to group JSON from each minion to a single line.

    Or setting the ``output_indent`` setting in the Master or Minion
    configuration file with one of the following values:

    * ``Null``: put each minion return on a single line.
    * ``pretty``: use four-space indents and sort the keys.
    * An integer: specify the indentation level.

Salt's outputters operate on a per-minion basis. Each minion return will be
output as a single JSON object once it comes in to the master.

Some JSON parsers can guess when an object ends and a new one begins but many
can not. A good way to differentiate between each minion return is to use the
single-line output format and to parse each line individually. Example output
(truncated)::

    {"dave": {"en0": {"hwaddr": "02:b0:26:32:4c:69", ...}}}
    {"jerry": {"en0": {"hwaddr": "02:26:ab:0d:b9:0d", ...}}}
    {"kevin": {"en0": {"hwaddr": "02:6d:7f:ce:9f:ee", ...}}}
    {"mike": {"en0": {"hwaddr": "02:48:a2:4b:70:a0", ...}}}
    {"phill": {"en0": {"hwaddr": "02:1d:cc:a2:33:55", ...}}}
    {"stuart": {"en0": {"hwaddr": "02:9a:e0:ea:9e:3c", ...}}}


CLI Example:

.. code-block:: bash

    salt '*' foo.bar --out=json
