Re: How accurate is the bandwidth chart on the fortigate dashboard status page
If I am not mistaken the history graph will grow/shrink the bandwidth graph for the duration indicated.
But check to see if any of the sessions is being handed off to Hardware acceleration. Someone correct me if I am wrong on this, but I'm under the impression that the fgt may not properly measure the throughput on hardware acceleration sessions.
That said, looking at the graph I don't see a bandwidth issue. Though you will want to set the graph to 24 hours or a week then check to see if the throughput peaks (max out) your ISP pipe at any one time. If the graph peaks near the top of the graph for any amount of time then go investigate (drill down) to these sessions to see what is causing the spike in traffic.
