Abstract: A manner of monitoring network performance using an AMA (active monitoring agent). A network manager, generally operating on one of the network nodes, establishes an AMA associated with two end points, at least one of the end points including a VM running an application. VM migration is monitored, and if a detected migration is associated with an active AMA then the new endpoint or endpoints associated with the AMA are calculated and a new AMA is established. A VM pair table is updated to reflect the change.

Abstract: The present invention includes in its several embodiments a system and method for resolving hubs and other forms of relay devices in a subnet comprising a plurality of nodes enabled with an adjacency-detection protocol. The method preferably comprises the steps of acquiring the adjacency table of each of the plurality of nodes, searching the adjacency table data for indications that a port is indirectly coupled to a plurality of other nodes through a hub, introducing an icon for each of the hubs in addition to icons for each of the plurality of nodes enabled with an adjacency-detection protocol, and logically coupling each hub to the associated nodes. Illustrations of the network topology generated using the preferred embodiment are therefore highly representative of the actual physical topology.
