+{{es}} includes a set of built-in {{ilm-init}} policies that govern how managed indices transition as they age. This guide demonstrates how you can customize the lifecycle of a managed index, to adjust how the index transitions across [data tiers](/manage-data/lifecycle/data-tiers.md) and what [actions](/manage-data/lifecycle/index-lifecycle-management/index-lifecycle.md#ilm-phase-actions), such as downsampling or shrinking, are performed on the index during each lifecycle phase.

-{{agent}} uses these policies to manage backing indices for its data streams. This tutorial shows you how to use {{kib}}’s **Index Lifecycle Policies** to customize these policies based on your application’s performance, resilience, and retention requirements.
+This tutorial gives the example of customizing how ingested logging data is managed. Rather than use the default lifecycle settings from the built-in `logs@lifecycle` {{ilm-init}} policy, you can use the **Index Lifecycle Policies** feature in {{kib}} to tailor a new policy based on your application’s specific performance, resilience, and retention requirements. This involves three main steps:
+ 1. [Create a duplicate of the `logs@lifecycle` policy](#example-using-index-lifecycle-policy-duplicate-ilm-policy).
+ 2. [Modify the new policy to suit your requirements](#ilm-ex-modify-policy).
+ 3. [Apply the new policy to your log data using a `logs@custom` component template](#example-using-index-lifecycle-policy-apply-policy).

+If you're using [Elastic integrations](https://docs.elastic.co/en/integrations) and are not yet familiar with which data streams are associated with them, refer to [Manage the lifecycle policy for integrations data](/manage-data/lifecycle/index-lifecycle-management/manage-lifecycle-integrations-data.md).
 
+If you're looking for a more advanced use case, such as customizing an ILM policy for a selected set of data streams in one or more integrations or namespaces, check the set of tutorials in [Customize data retention policies](/reference/fleet/data-streams-ilm-tutorial.md) in the {{fleet}} and {{agent}} reference documentation.
