I have to develop a software module for learning authomaticaly the topology of a networks in virtualized enviromenment(NFV/VNFs). The NFV/VNFs is simulated through virtual machines,based on Linux,interconnected in OpenStack environment. The Ceilometer tool colects info aboit CPU,RAM,interfaces,load in a data base,then are exposed on a Web page.

You can easily list all Neutron networks and their respective subnets, as well as all routers and the subnets that they connect. With this information and a smart program you should be able to work out the topology. I doubt that Ceilometer would be of much help.

If not (only) routers but (also) virtual machines are used to connect networks together, you can easily list the subnets of those virtual machines as well.

I have no experience with NFV. To me, the problem description is a bit vague; with more details I or other people could give a better answer. For example, what kind of information is required or helpful to discover the topology.
