There are utilization reports that go by either average or min/max/avg bits transferred. You can parse it down by switch or site in the report configuration if you so choose.
Under new reports, it would be an "interface chart." I usually just do a search for the word "max" and you'll see the min/max/average bits per second report. Then you can customize from there. I use that same report for all of my uplinks from multiple sites to get more visibility into the amount of traffic going from site to site.
Hope that helps.
I mis-spoke using the term report. I actually built a live page using "Traffic & Percentage Utilization of each Interface - Node Detail Reports"
What we are running into are remote sites with very high utilization of their bandwidth and I need to track it back to which device, on which port of the switch is causing all the traffic. (Yes, there's likely something very obvious that I'm looking right at and don't see - A did you plug it in type of thing. But I figure it's better to ask the question and get egg on my face than to keep wondering around)
If that's the case, unfortunately I'm not familiar with anything like that. We utilize the SolarWinds NTA at my workplace, so we can drill down a little more and have a "live" feed of conversations based on endpoints using Netflow. So I'm able to see that type of data (sometimes only layer 3 and then having to work my way backwards) but for NPM, I'm not sure of any live "reporting."
Sorry I couldn't be of more assistance.
Based on what you mentioned, NetFlow Traffic Analyzer and possibly User Device Tracker can both be used to obtain this information.
Network Performance Monitor will report the interface bandwidth, but you want to see what traffic within the bandwidth is all of the information coming/going, this is where NetFlow would fit in to report Source/Destination IP/Hostnames, Ports, packets and bytes per port conversation.
Combine NetFlow with User Device Tracker and you will get a correlated view of where the system is located down to switch port. it can also report the user account logged in recently with AD contact details and AD group assignments.
