== {ilm-init}: Manage the index lifecycle

// [partintro]
--
You can configure {ilm} ({ilm-init}) policies to automatically manage indices
according to your performance, resiliency, and retention requirements.
For example, you could use {ilm-init} to:

* Spin up a new index when an index reaches a certain size or number of documents
* Create a new index each day, week, or month and archive previous ones
* Delete stale indices to enforce data retention standards

You can create and manage index lifecycle policies through {kib} Management
or the {ilm-init} APIs. Default {ilm} policies are created automatically
when you use {agent}, {beats}, or the {ls} {es} output plugin to send data
to the {stack}.
