Previews a {dfeed}.

* If {es} {security-features} are enabled, you must have `monitor_ml`, `monitor`,
|
|
`manage_ml`, or `manage` cluster privileges to use this API. See
|
|
{stack-ov}/security-privileges.html[Security privileges].

|
[[ml-preview-datafeed-desc]]
|
|
==== {api-description-title}
|
|
|
|
The preview {dfeeds} API returns the first "page" of results from the `search`
|
|
that is created by using the current {dfeed} settings. This preview shows the
|
|
structure of the data that will be passed to the anomaly detection engine.
|
|
|
|
IMPORTANT: When {es} {security-features} are enabled, the {dfeed} query is
|
|
previewed using the credentials of the user calling the preview {dfeed} API.
|
|
When the {dfeed} is started it runs the query using the roles of the last user
|
|
to create or update it. If the two sets of roles differ then the preview may
|
|
not accurately reflect what the {dfeed} will return when started. To avoid
|
|
such problems, the same user that creates/updates the {dfeed} should preview
|
|
it to ensure it is returning the expected data.
