When a map image layer is created in Portal, what is the underlying component that references the image layer to a service endpoint? For instance, should I be able to see the Item ID in a stack trace for a rest endpoint? Is there a way to view analytics on a map image layer? My organization has duplicated image layers, but we do not consume the image layers into web maps, we use the service URLs, however if we delete the wrong image layer, the service will delete completely also. This is a federated 10.6.1 Portal environment.
