Index lifecycle management settings in Elasticsearchedit
These are the settings available for configuring index lifecycle management (ILM).
Cluster level settingsedit
-
xpack.ilm.enabled
-
(boolean)
Whether ILM is enabled or disabled, setting this to
false
disables any ILM REST API endpoints and functionality. Defaults totrue
. -
indices.lifecycle.history_index_enabled
-
(boolean)
Whether ILM’s history index is enabled. If enabled, ILM will record the
history of actions taken as part of ILM policies to the
ilm-history-*
indices. Defaults totrue
. -
indices.lifecycle.poll_interval
-
(Dynamic, time unit value)
How often index lifecycle management checks for indices that meet policy criteria. Defaults to
10m
.
Index level settingsedit
These index-level ILM settings are typically configured through index templates. For more information, see Create a lifecycle policy.
-
index.lifecycle.indexing_complete
-
(Dynamic, boolean)
Indicates whether or not the index has been rolled over.
Automatically set to
true
when ILM completes the rollover action. You can explicitly set it to skip rollover. Defaults tofalse
. -
index.lifecycle.name
- (Dynamic, string) The name of the policy to use to manage the index.
-
index.lifecycle.origination_date
- (Dynamic, long) If specified, this is the timestamp used to calculate the index age for its phase transitions. Use this setting if you create a new index that contains old data and want to use the original creation date to calculate the index age. Specified as a Unix epoch value.
-
index.lifecycle.parse_origination_date
-
(Dynamic, boolean)
Set to
true
to parse the origination date from the index name. This origination date is used to calculate the index age for its phase transitions. The index name must match the pattern^.*-{date_format}-\\d+
, where thedate_format
isyyyy.MM.dd
and the trailing digits are optional. An index that was rolled over would normally match the full format, for examplelogs-2016.10.31-000002
). If the index name doesn’t match the pattern, index creation fails. -
index.lifecycle.rollover_alias
- (Dynamic, string) The index alias to update when the index rolls over. Specify when using a policy that contains a rollover action. When the index rolls over, the alias is updated to reflect that the index is no longer the write index. For more information about rolling indices, see Rollover.
