[[ml-get-dfanalytics-request]]
==== {api-request-title}

`GET _ml/data_frame/analytics/<data_frame_analytics_id>` +

`GET _ml/data_frame/analytics/<data_frame_analytics_id>,<data_frame_analytics_id>` +

`GET _ml/data_frame/analytics/` +

[[ml-get-dfanalytics-prereq]]
==== {api-prereq-title}

* You must have `monitor_ml` privilege to use this API. For more 
information, see <<security-privileges>> and <<built-in-roles>>.

[[ml-get-dfanalytics-desc]]
==== {api-description-title}

You can get information for multiple {dfanalytics-jobs} in a single API request 
by using a comma-separated list of {dfanalytics-jobs} or a wildcard expression.

[[ml-get-dfanalytics-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}. You can get information for all {dfanalytics-jobs} by 
  using _all, by specifying `*` as the `<data_frame_analytics_id>`, or by 
  omitting the `<data_frame_analytics_id>`.

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

`data_frame_analytics`::
  (array) An array of {dfanalytics-job} resources. For more information, see
  <<ml-dfanalytics-resources>>.

[[ml-get-dfanalytics-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.

[[ml-get-dfanalytics-example]]
==== {api-examples-title}

The following example gets configuration information for the `loganalytics` 
{dfanalytics-job}:
