Index lifecycle management settingsedit

These are the settings available for configuring Index Lifecycle Management

Cluster level settingsedit

Whether ILM is enabled or disabled, setting this to false disables any ILM REST API endpoints and functionality. Defaults to true.

Index level settingsedit

These index-level ILM settings are typically configured through index templates. For more information, see Setting up a policy.
The name of the policy to use to manage the index.
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 rollover, see Using policies to manage index rollover.
When configured to true the origination date will be parsed from the index name. The index format must match the pattern ^.*-{date_format}-\\d+, where the date_format is yyyy.MM.dd and the trailing digits are optional (an index that was rolled over would normally match the full format eg. logs-2016.10.31-000002). If the index name doesn’t match the pattern the index creation will fail.
The timestamp that will be used to calculate the index age for its phase transitions. This allows the users to create an index containing old data and use the original creation date of the old data to calculate the index age.
