# APM settings in Kibana
These settings allow the APM app to function, and specify the data that it surfaces. Unless you’ve customized your setup, you do not need to configure any settings to use the APM app. It is enabled by default.
<note>
  If a setting is applicable to Elastic Cloud Hosted environments, its name is followed by this icon: ![logo cloud](https://doc-icons.s3.us-east-2.amazonaws.com/logo_cloud.svg "Supported on Elastic Cloud Hosted")
</note>


## APM indices

The APM app uses data views to query APM indices. To change the default APM indices that the APM app queries, open the APM app and select **Settings** > **Indices**. Index settings in the APM app take precedence over those set in `kibana.yml`.
APM indices are Kibana space-aware; changes to APM index settings will only apply to the currently enabled space.

## General APM settings

If you’d like to change any of the default values, copy and paste the relevant settings into your `kibana.yml` configuration file. Changing these settings may disable features of the APM App.
<tip>
  More settings are available in the [Observability advanced settings](/elastic/docs-builder/docs/3016/reference/kibana/advanced-settings#observability-advanced-settings).
