=== Delete Lifecycle Policy API
++++
<titleabbrev>Delete Policy</titleabbrev>
++++
Deletes an existing lifecycle policy
==== Request
`DELETE _ilm/<policy>`
==== Description
Deletes an existing lifecycle policy
==== Path Parameters
`policy` (required)::
(string) Identifier for the policy.
==== Request Parameters
`timeout`::
(time units) Specifies the period of time to wait for the completion of the
DELETE operation. When this period of time elapses, the API fails and returns
an error. The default value is `30s`. For more information about time units,
see <<time-units>>.
`master_timeout`::
(time units) Specifies the period of time to wait for the connection with master.
When this period of time elapses, the API fails and returns an error.
The default value is `30s`. For more information about time units, see <<time-units>>.
==== Examples
The following example deletes an existing policy named `my_policy`:
//////////////////////////
[source,js]
--------------------------------------------------
PUT _ilm/my_policy
{
"policy": {
"phases": {
"warm": {
"minimum_age": "10d",

[[ilm-explain]]
=== Explain Lifecycle API
++++
<titleabbrev>Explain Lifecycle</titleabbrev>
++++
Shows the current lifecycle status for an index.
==== Request
`GET <index>/_ilm/explain`
==== Description
This API returns information relating to the current lifecycle state of an
index. This includes information such as the currently executing phase, action,
and step and the timestamp when the index entered them. It also shows the
definition of the current phase that is being run and in the event that there
has been a failure, information regarding the failure.
==== Path Parameters
`index` (required)::
(string) Identifier for the index.
==== Request Parameters
`timeout`::
(time units) Specifies the period of time to wait for the completion of the
GET operation. When this period of time elapses, the API fails and returns
an error. The default value is `30s`. For more information about time units,
see <<time-units>>.
`master_timeout`::
(time units) Specifies the period of time to wait for the connection with master.
When this period of time elapses, the API fails and returns an error.
The default value is `30s`. For more information about time units, see <<time-units>>.
==== Examples
The following example retrieves the lifecycle state for the index `my_index`:
//////////////////////////

--------------------------------------------------
PUT _ilm/my_policy
{
"policy": {
"phases": {
"warm": {
"minimum_age": "10d",

ILM the other fields will not be shown
<2> The name of the policy which ILM is using for this index
<3> Shows whether ILM execution for the index is currently set to be skipped
<4> The timestamp used for the `minimum_age`

<10> The timestamp for when the index entered the current step
When the policy is running on the index the response will contain a
`phase_execution` object that describes the exact phase that is being run.
Changes to the underlying policy will not affect this index until the current
phase definition has been completely executed.

<1> `step_info` shows information about what ILM is waiting for on this index.
In this case we are waiting for all shard copies of the index to be active.
If the index is in the ERROR step, something has gone wrong when executing a
step in the policy and will need to be investigated and resolved for the index
to make progress. TO help determine how to resolve the error the explain response
will show the step that failed in `failed_step`, and the information on the error
that occurred in `step_info`.

=== Move To Step API
++++
<titleabbrev>Move To Step</titleabbrev>
++++
Moves a managed index into a specific execution step its policy
==== Request
`POST _ilm/move/<index>`
==== Description
WARNING: This is an expert API that may lead to unintended data loss. When used,
an index's policy will begin executing at the specified step. It will execute
the step specified even if it has already executed it. Since this is a, potentionally,
dangerous action, specifying both the current step and next step to move to is
required in the body of the request.
This API changes the current step for the specified index to the step supplied in the body of the request
==== Path Parameters
`index` (required)::
(string) Identifier for the index.
==== Request Parameters
`timeout`::
(time units) Specifies the period of time to wait for the completion of the
move operation. When this period of time elapses, the API fails and returns
an error. The default value is `30s`. For more information about time units,
see <<time-units>>.
`master_timeout`::
(time units) Specifies the period of time to wait for the connection with master.
When this period of time elapses, the API fails and returns an error.
The default value is `30s`. For more information about time units, see <<time-units>>.
==== Examples
The following example moves the index `my_index` from the initial step to the
forcemerge step:
//////////////////////////

PUT _ilm/my_policy
{

(time units) Specifies the period of time to wait for the connection with master.
When this period of time elapses, the API fails and returns an error.
The default value is `30s`. For more information about time units, see <<time-units>>.

=== Set Policy On Index API
++++
<titleabbrev>Set Policy On Index</titleabbrev>
++++
Assigns a policy to an index for management.
==== Request
`POST <index>/_ilm/<policy>`
==== Description
This action assigns a policy to an index. It is effectively the same as setting an index's
`index.lifecycle.name` setting.
==== Path Parameters
`index` (required)::
(string) Identifier for the index.
`policy` (required)::
(string) Identifier for the policy.
==== Request Parameters
`timeout`::
(time units) Specifies the period of time to wait for the completion of the
operation. When this period of time elapses, the API fails and returns
an error. The default value is `30s`. For more information about time units,
see <<time-units>>.
`master_timeout`::
(time units) Specifies the period of time to wait for the connection with master.
When this period of time elapses, the API fails and returns an error.
The default value is `30s`. For more information about time units, see <<time-units>>.
==== Examples
The following example assigns a policy `my_policy` to an index `my_index`.

Start the ILM plugin
==== Request
`POST /_ilm/start`

been stopped using the <<ilm-stop, Stop ILM API>>.
==== Request Parameters
`timeout`::
(time units) Specifies the period of time to wait for the completion of the
start operation. When this period of time elapses, the API fails and returns
an error. The default value is `30s`. For more information about time units,
see <<time-units>>.
`master_timeout`::
(time units) Specifies the period of time to wait for the connection with master.
When this period of time elapses, the API fails and returns an error.
The default value is `30s`. For more information about time units, see <<time-units>>.
