A way to monitor "who" is talking to a node or interface

FormerIdeaCreator

I would like to see a way where I can identify a node or interface and then "watch" the bandwidth usage and see who is talking to this node or interface the most.  It would be like the Top 10 utilization, but for this particular node or interface.  The challenge I have is: a server will witness a spike in traffic and I want to see where or who it is going to or from.

Although not a feature of NPM itself, you could enable flow monitoring on the network devices and then use the Netflow Traffic Analyzer to monitor traffic to that particular node/interface.

I don't think NPM is capable of this as polling cannot track that type of information.
