Get transform statistics API

edit

Retrieves usage information for transforms.

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

Request

edit

GET _data_frame/transforms/<transform_id>/_stats

GET _data_frame/transforms/<transform_id>,<transform_id>/_stats

GET _data_frame/transforms/_stats

GET _data_frame/transforms/_all/_stats

GET _data_frame/transforms/*/_stats

Prerequisites

edit
  • If the Elasticsearch security features are enabled, you must have monitor_data_frame_transforms cluster privileges to use this API. The built-in data_frame_transforms_user role has these privileges. For more information, see Security privileges and Built-in roles.

Description

edit

You can get statistics for multiple transforms in a single API request by using a comma-separated list of identifiers or a wildcard expression. You can get statistics for all transforms by using _all, by specifying * as the <transform_id>, or by omitting the <transform_id>.

Path parameters

edit
<transform_id>
(Optional, string) Identifier for the transform. It can be a transform identifier or a wildcard expression. If you do not specify one of these options, the API returns information for all transforms.

Query parameters

edit
allow_no_match

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

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

Response body

edit
transforms
(array) An array of statistics objects for transforms, which are sorted by the id value in ascending order.

Response codes

edit
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.

Examples

edit

The following example skips for the first five transforms and gets usage information for a maximum of ten results:

GET _data_frame/transforms/_stats?from=5&size=10

The following example gets usage information for the ecommerce_transform transform:

GET _data_frame/transforms/ecommerce_transform/_stats

The API returns the following results:

{
  "count" : 1,
  "transforms" : [
    {
      "id" : "ecommerce_transform",
      "state" : {
        "task_state" : "started",
        "indexer_state" : "started",
        "checkpoint" : 1,
        "progress" : {
          "total_docs" : 1220,
          "docs_remaining" : 0,
          "percent_complete" : 100.0
        }
      },
      "stats" : {
        "pages_processed" : 2,
        "documents_processed" : 1220,
        "documents_indexed" : 13,
        "trigger_count" : 1,

      },
      "checkpointing" : {
        "current" : {

        },
        "operations_behind" : 0
      }
    }
  ]
