I have frequently have problems with saturated network circuits. NTA has been valuable in helping me find what is going on. I often get asked how much traffic on my network circuit is used by MS Exchange email, IP video, ERP system, and CRM system. Is there way to create a view where I can capture the flow by IP address groups? For example, I want create a view called, "Types of Applications". Within it would be a collection of total netflow info for my three exchange servers, total netflow info for my ERP system, etc...
