Instance Graph
The instance graph gives a visual overview of how a managed instance is being used, how it is related to other instances, and, maybe most importantly, how roots are preventing it from being garbage collected.
It is available under the type instance details view where it will present the instance graph for the currently selected instance.
The graph can include all instances that are related to the selected instance. This includes instances and roots that can reach the selected instance, and instances that are reachable from the selected instance. By default, only root path instances and held instances are included in the graph, i.e. the instances and roots that are preventing the selected instance from being garbage collected and the instances that are uniquely reachable from the selected instance. For more information about reachable and held instances, see Held and Reachable Instances. For more information about root paths in the graph, see Root Paths in the Graph
