|
|
|
|
`GET <index>/_ilm/explain`
|
|
|
|
==== Description
|
|
|
|
Retrieves information about the index's current lifecycle state, such as
|
|
the currently executing phase, action, and step. Shows when the index entered
|
|
each one, the definition of the running phase, and information
|
|
about any failures.
|
|
|
|
==== Path Parameters
|
|
|
|
`index` (required)::
|
|
(string) Identifier for the index.
|
|

|
include::{docdir}/rest-api/timeoutparms.asciidoc[]
|
|
|
|
==== Authorization

|
|
|
You must have the `view_index_metadata` or `manage_ilm` or both privileges on the indices
|
|

When management of the index is first taken over by ILM, `explain` shows

that the index is managed and in the `new` phase:

Changes to the underlying policy will not affect this index until the current

<1> Status of the step that's in progress.

|
|
|
If the index is in the ERROR step, something went wrong while executing a
|
|
step in the policy and and you will need to take action for the index to proceed
|
|
to the next step. To help you diagnose the problem, the explain response shows
|
|
the step that failed and the step info provides information about the error.
