=== Get {dataframe-transform} stats API

Retrieves the operational statistics of one or more {dataframe-transforms}.
The API accepts a +{request}+ object and returns a +{response}+.

[id="{upid}-{api}-request"]
==== Get {dataframe-transform} stats request

A +{request}+ requires a data frame transform id or the special wildcard `_all`
to get the statistics for all {dataframe-transforms}.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------
<1> Constructing a new GET Stats request referencing an existing {dataframe-transform}

==== Optional arguments

The following arguments are optional.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-options]
--------------------------------------------------
<1> The page parameters `from` and `size`. `from` specifies the number of
{dataframe-transform} stats to skip.
`size` specifies the maximum number of {dataframe-transform} stats to get.
Defaults to `0` and `100` respectively.
<2> Whether to ignore if a wildcard expression matches no transforms.

[id="{upid}-{api}-response"]
==== Response

The returned +{response}+ contains the requested {dataframe-transform} statistics.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-response]
--------------------------------------------------
<1> The response contains a list of `DataFrameTransformStats` objects
<2> The running state of the transform, for example `started`, `indexing`, etc.
<3> The overall transform statistics recording the number of documents indexed etc.
<4> The progress of the current run in the transform. Supplies the number of docs left until the next checkpoint
and the total number of docs expected.
<5> The assigned node information if the task is currently assigned to a node and running.
