|
|
|
* You must create an {anomaly-job} before you create a {dfeed}.
|
|
* If {es} {security-features} are enabled, you must have `manage_ml` or `manage`
|
|
cluster privileges to use this API. See
|
|
<<security-privileges>>.

[[ml-put-datafeed-desc]]
|
|
==== {api-description-title}
|
|
|
|
{ml-docs}/ml-dfeeds.html[{dfeeds-cap}] retrieve data from {es} for analysis by
|
|
an {anomaly-job}. You can associate only one {dfeed} to each {anomaly-job}.
|
|
|
|
The {dfeed} contains a query that runs at a defined interval (`frequency`). If
|
|
you are concerned about delayed data, you can add a delay (`query_delay`) at
|
|
each interval. See {ml-docs}/ml-delayed-data-detection.html[Handling delayed data].
|
|
|
|
[IMPORTANT]
|
|
====
|
|
* You must use {kib} or this API to create a {dfeed}. Do not put a
|
|
{dfeed} directly to the `.ml-config` index using the {es} index API. If {es}
|
|
{security-features} are enabled, do not give users `write` privileges on the
|
|
`.ml-config` index.
|
|
* When {es} {security-features} are enabled, your {dfeed} remembers which roles
|
|
the user who created it had at the time of creation and runs the query using
|
|
those same roles.
