Retrieves usage information for {dfeeds}.

* If the {es} {security-features} are enabled, you must have `monitor_ml`,
`monitor`, `manage_ml`, or `manage` cluster privileges to use this API. See
<<security-privileges>>.
[[ml-get-datafeed-stats-desc]]
== {api-description-title}
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`.
IMPORTANT: This API returns a maximum of 10,000 {dfeeds}.

If you do not specify one of these options, the API returns information about
all {dfeeds}.
