Resource map components

Map views

There are two views available in the Application Load Balancer resource map: Overview, and Unhealthy Target Map. Overview is selected by default and displays all of your load balancer's resources. Selecting the Unhealthy Target Map view will only display the unhealthy targets and the resources associated to them.

The Unhealthy Target Map view can be used to troubleshoot targets that are failing health checks. For more information, see Troubleshoot unhealthy targets using the resource map.
