Returns defaults and limits used by machine learning.

==== Request

`GET _ml/info`

==== Description

This endpoint is designed to be used by a user interface that needs to fully
understand machine learning configurations where some options are not specified,
meaning that the defaults should be used.  This endpoint may be used to find out
what those defaults are.


==== Authorization

You must have `monitor_ml`, `monitor`, `manage_ml`, or `manage` cluster
privileges to use this API.  The `machine_learning_admin` and `machine_learning_user`
roles provide these privileges. For more information, see
{stack-ov}/security-privileges.html[Security Privileges] and
{stack-ov}/built-in-roles.html[Built-in Roles].
