What is the best report to see bandwidth utilization on a single node for last 48 hours?
Report or Resource? With report I use the "Average and Peak Traffic Rates - Last X" but you need to copy and edit it in report writer to be the time frame you want and to filter it to specific nodes or interfaces. By itself if you have even a slightly large environment gets out of hand really quick. From a resource point of view I really like the "Maximum Traffic Today" resource, I put it on every backbone link, wan link, and every port channel or top of rack switch link in my DC. Displayed on a custom map and/or interface details.

If you have NTA running you can limit the view down to a single node/IP Address and then actually parse all of the bandwidth to let you know exactly what Applications are being used, who is on the other end of the conversation etc. Just this week, after turning on NTA we found this little GEM in our network
I just click on the interface in question, and then use the Percent Utilization - Line Chart view. Then I click on the Edit button and adjust as needed.
