Get data frame analytics jobs API

edit

Retrieves configuration information for data frame analytics jobs.

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

Request

edit

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/

GET _ml/data_frame/analytics/_all

Prerequisites

edit

If the Elasticsearch security features are enabled, you must have the following privileges:

  • cluster: monitor_ml

For more information, see Security privileges and Built-in roles.

Description

edit

You can get information for multiple data frame analytics jobs in a single API request by using a comma-separated list of data frame analytics jobs or a wildcard expression.

Path parameters

edit
<data_frame_analytics_id>

(Optional, string) Identifier for the data frame analytics job. If you do not specify this option, the API returns information for the first hundred data frame analytics jobs.

You can get information for all data frame analytics jobs by using _all, by specifying * as the <data_frame_analytics_id>, or by omitting the <data_frame_analytics_id>.

Query parameters

edit
allow_no_match

(Optional, boolean) Specifies what to do when the request:

  • Contains wildcard expressions and there are no data frame analytics 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 data frame analytics jobs. The default value is 0.
size
(Optional, integer) Specifies the maximum number of data frame analytics jobs to obtain. The default value is 100.

edit

The following example gets configuration information for the loganalytics data frame analytics job:

GET _ml/data_frame/analytics/loganalytics

The API returns the following results:

{
    "count": 1,
    "data_frame_analytics": [
        {
            "id": "loganalytics",
            "source": {
                "index": "logdata",
                "query": {
                    "match_all": {}

            },
            "analysis": {
                "outlier_detection": {}
            },
