What is Topology in Network Watcher good for?

As resources are added to a virtual network, it can become difficult to understand what resources are in a virtual network and how they relate to each other. The topology capability enables you to generate a visual diagram of the resources in a virtual network and the relationships between the resources.

The resources shown in the diagram are a subset of the networking components in the virtual network. For example, while a network security group is shown, the security rules within it are not shown in the diagram. Though not differentiated in the diagram, the lines represent one of two relationships: Containment or associated. To see the full list of resources in the virtual network, and the type of relationship between the resources, generate the topology with PowerShell or the Azure CLI.
