I had a requirement to send an alert for a particular interface with the utilization chart and other details related like top conversations, Top applications etc.. I tried top talkers alert and it was little challenging as I could not customize as required for instance I cannot have in PDF etc.. So I decide to create a report as attached and run in scheduled intervals so that team can quickly take an action.You can also add top applications, Top domains etc.. in this for a much meaning full report. This report has helped my team to reduce their efforts.
Incase if someone else has any other better way please suggest. NetFlow Traffic Analyzer
