* You must have `monitor_ml` privilege to use this API. For more 
information, see {stack-ov}/security-privileges.html[Security privileges] and 
{stack-ov}/built-in-roles.html[Built-in roles].


[[ml-get-dfanalytics-stats-path-params]]
==== {api-path-parms-title}

`<data_frame_analytics_id>`::
  (Optional, string)Identifier for the {dfanalytics-job}. If you do not specify
  one of these options, the API returns information for the first hundred
  {dfanalytics-jobs}.


[[ml-get-dfanalytics-stats-query-params]]
==== {api-query-parms-title}

`allow_no_match`::
  (Optional, boolean) Specifies what to do when the request:
+
--
* Contains wildcard expressions and there are no {dfanalytics-jobs} that match.
* Contains the `_all` string or no identifiers and there are no matches.
* Contains wildcard expressions and there are only partial matches. 

The default value is `true`, which returns an empty `data_frame_analytics` array 
when there are no matches and the subset of results when there are partial 
matches. If this parameter is `false`, the request returns a `404` status code 
when there are no matches or only partial matches.
--

`from`::
  (Optional, integer) Skips the specified number of {dfanalytics-jobs}. The
  default value is `0`.

`size`::
  (Optional, integer) Specifies the maximum number of {dfanalytics-jobs} to
  obtain. The default value is `100`.


[[ml-get-dfanalytics-stats-response-body]]
==== {api-response-body-title}

The API returns the following information:

`data_frame_analytics`::
  (array) An array of statistics objects for {dfanalytics-jobs}, which are
  sorted by the `id` value in ascending order.
  
  `id`::
    (string) The unique identifier of the {dfanalytics-job}.
    
  `state`::
    (string) Current state of the {dfanalytics-job}.
    
  `progress`::
    (array) The progress report of the {dfanalytics-job} by phase.
    
    `phase`::
      (string) Defines the phase of the {dfanalytics-job}. Possible phases: 
      `reindexing`, `loading_data`, `analyzing`, and `writing_results`.
      
    `progress_percent`::
      (integer) The progress that the {dfanalytics-job} has made expressed in 
      percentage.


[[ml-get-dfanalytics-stats-response-codes]]
==== {api-response-codes-title}

`404` (Missing resources)::
  If `allow_no_match` is `false`, this code indicates that there are no
  resources that match the request or only partial matches for the request.
