|
|
|
|
* 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>`.
|
|
|
|
|
|
[[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) 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`.
|
|
|
|
[[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:
