We have a ton of netflow sources, some displaying WAN traffic and some displaying Internet Traffic. Is there a way in NTA to group these? I was thinking along the lines one group called Internet and another called WAN, then assign nodes to either one or the other with a custom property or something and display it in NTA.
You could group them as IP Address Groups, in NTA settings. If they don't have contiguous IP address it can be pretty time consuming though. I'll mark this for a PM to comment as well.
