=== Get {dfeed-cap} Statistics

The get {dfeed} statistics API enables you to retrieve usage information for
{dfeeds}.


==== Request


`GET _xpack/ml/datafeeds/<feed_id>/_stats` +

`GET _xpack/ml/datafeeds/<feed_id>,<feed_id>/_stats` +

`GET _xpack/ml/datafeeds/_stats`  +

`GET _xpack/ml/datafeeds/_stats/_all` +



==== Description

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

If the {dfeed} is stopped, the only information you receive is the
`datafeed_id` and the `state`.


==== Path Parameters

`feed_id`::
  (string) Identifier for the {dfeed}. It can be a {dfeed} identifier or a
  wildcard expression. If you do not specify one of these options, the API
  returns statistics for all {dfeeds}.


==== Results

The API returns the following information:

`datafeeds`::
  (array) An array of {dfeed} count objects.
  For more information, see <<ml-datafeed-counts>>.


==== Authorization

privileges to use this API. For more information, see
{xpack-ref}/security-privileges.html[Security Privileges].
