View Historical Bandwidth Usage On FortiGate 200A Including Amount Of Bandwidth Per Protocol

A company asked me to analyze some of their network traffic to verify some of the projects they are working on to cut costs won’t impact their business. One of the projects includes removing a 100 Mbps fiber connection to their colocation and replacing it with a cable modem that is asynchronous with 50 Mbps download and 5 Mbps upload. Unfortunately they do not have any solid historical network data capture software such as Cacti so before setting up such a service I had to provide initial data via what was available. One of the tools I was able to use was the dashboard data that lives in memory on their FortiGate 200A. Below is information on where to find this information in the FortiGate 200A dashboard.
