Techniques to display a graphic representation of a computer network topology are described. In one example, a network device is configured to generate an output comprising a graphic representation of a topology of a computer network, the computer network comprising compute nodes interconnected by a packet-based communications network provided by a set of network devices, wherein the policy controller is further configured to: identify, amongst the compute nodes or the network devices, a network element having state information indicating an operational state of interest; modify state information for one or more resources that are coupled to the identified network element; and based upon whether the network topology information indicates a visible graphic symbol for the identified network element, output a visual indicator corresponding to the visible graphic symbol or corresponding to a visible resource that is communicably coupled to the identified network element.
