Monitoring traffic load
Heavy traffic loads can cause sustained high CPU or RAM usage. If this is unusual, no action is required. However, sustained heavy traffic load might indicate that you need a more powerful FortiADC model.
In the web UI, you can view traffic load two ways:
Monitor current HTTP traffic on the dashboard. Go to System >  Dashboard  >  Virtual Server and examine the throughput graphs.
Examine traffic history in the traffic log. Go to Logs & Report >  Log Browsing > Traffic Log.
