[[get-data-frame-transform-stats-prereqs]]
==== {api-prereq-title}
* 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-desc]]
==== {api-description-title}
You can get statistics for multiple {dataframe-transforms} in a single API
request by using a comma-separated list of identifiers or a wildcard expression.
You can get statistics for all {dataframe-transforms} by using `_all`, by
specifying `*` as the `<data_frame_transform_id>`, or by omitting the
`<data_frame_transform_id>`.
[discrete]
[[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}.
[discrete]
[[get-data-frame-transform-stats-query-parms]]
==== {api-query-parms-title}
`allow_no_match` (Optional)::
(boolean) Specifies what to do when the request:
+
--
* Contains wildcard expressions and there are no {dataframe-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 {dataframe-transforms}. The
default value is `0`.
`size` (Optional)::
(integer) Specifies the maximum number of {dataframe-transforms} to obtain.
The default value is `100`.
[discrete]
[[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-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.

[[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:
[source,js]
