Hi, I've been using NetFlow for a couple months and I'm still not really sure how to use it to it's full potential. First, I'm not sure that everything is configured for best results. Which widgets are best to have for a "network snapshot"?

Also, lets say I have a scenario where my network starts moving slowly. I open NetFlow, and assuming all my interfaces are sending NetFlow data, where do I start? What do I look for? I can see tons and tons of data, but I also seem to be missing some data. For example, I would download a huge file from the internet. But under "conversations", that transaction did not ever appear.

Is there any best practices guide, or a scenario-based step by step guide? If not, I think this information would be valuable.
