Historical bandwidth utilization graph and report on FortiAnalyzer
This KB is about v5. Maybe v6 allow this kind of report that all of us wants.
Here the comments from Fortinet TAC:
The measurement of the bandwidth of an interface is a metric obtained from the FortiGate memory, so a more related device to make this measurement is an SNMP server.
The FAZ reports will generate bandwidth measurements depending on the host, application or user element, for example measuring how much bandwidth a certain device consumes in a day.
