=== Get {dfeed-cap} Statistics API
++++
<titleabbrev>Get {dfeed-cap} Statistics</titleabbrev>
++++
Retrieves 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/_all/_stats` +
==== 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
You must have `monitor_ml`, `monitor`, `manage_ml`, or `manage` cluster
privileges to use this API. For more information, see
{xpack-ref}/security-privileges.html[Security Privileges].
