Thank you so much jswan
This I got but still my question do I need to add nodes such as computers and users so I can monitor the bandwidth or all I need are just the router and the switches. I only have licenses for 100 NTA so this way I just want to be able to monitor bandwidth that is all I need. I mean do I need to discover all nodes and all users or just the router will give me a good picture of who is using the internet the most and where are they going what sites.
The only reason I installed NPM is because you cannot install NTA without it.
I appreciate the quick reply.
