APM app settings

edit

You do not need to configure any settings to use the APM app. It is enabled by default.

APM Indices

edit

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.

Starting in version 8.2.0, APM indices are Kibana Spaces-aware; Changes to APM index settings will only apply to the currently enabled space. See Control access to APM data for more information.

General APM settings
