Techniques for implementing a virtual tap in a virtual topology are described. A request to tap a particular link between a set of virtual topology entities (VTEs) is received. The particular link between the set of VTEs is mapped to a link between a set of instantiated entities in a physical topology. One of the instantiated elements implements a tapping function. Additionally or alternatively, a tapping element is instantiated and the tapping element implements the tapping function. The tapping element is not one of the set of instantiated entities. The tapping function includes: applying a tap filter to a set of data; replicating the data that passes the tap filter; and transmitting the replicated data to a virtual endpoint. The replicated data may be referred to as “tapped data.” A user interface engine presents information regarding the particular link between the set of VTEs based on the tapped data.
