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

Index defaults can be changed in Kibana. Open the main menu, then click APM > Settings > Indices. Index settings in the APM app take precedence over those set in kibana.yml.

General APM settings
