If the {es} {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 {stack-ov}/security-privileges.html[Security privileges] and
{stack-ov}/built-in-roles.html[Built-in roles].

[[get-data-frame-transform-stats-path-parms]]
==== {api-path-parms-title}

`<data_frame_transform_id>` (Optional)::
  (string) Identifier for the {dataframe-transform}. It can be a
  {dataframe-transform} identifier or a wildcard expression. If you do not
  specify one of these options, the API returns information for all
  {dataframe-transforms}.

[[get-data-frame-transform-stats-query-parms]]
==== {api-query-parms-title}

`allow_no_match` (Optional)::
  (boolean) Whether to ignore if a wildcard expression matches no
  {dataframe-transforms}. This includes `_all` string or when no transforms have
  been specified. The default is `true`.

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

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

[[get-data-frame-transform-stats-response]]
==== {api-response-body-title}

`transforms`::
  (array) An array of statistics objects for {dataframe-transforms}, which are
  sorted by the `id` value in ascending order.

[[get-data-frame-transform-stats-example]]
==== Examples

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

[source,js]
--------------------------------------------------
GET _data_frame/transforms/_stats?from=5&size=10
--------------------------------------------------
// CONSOLE
// TEST[skip:todo]

The following example gets usage information for the `ecommerce_transform`
{dataframe-transform}:

[source,js]
--------------------------------------------------
GET _data_frame/transforms/ecommerce_transform/_stats
--------------------------------------------------
// CONSOLE
// TEST[skip:todo]

The API returns the following results:
