Abstract

Generating discovery profiles for discovering components of a computer network using agent software can include receiving a command from a client device to generate a discovery profile for an agent software instance. A network subnet and at least one network gateway address can be obtained from the agent software instance, which network subnet and at least one network gateway address can be associated with a network interface of the computing device operating the agent software. At least one other network subnet can be obtained from the agent software instance by sending instructions to the agent software instance to identify the at least one other network subnet using the at least one network gateway address. A discovery profile including the network subnet and the at least one other network subnet can then be generated for the agent software instance.
