Visual Display of Bandwidth Usage (Bandwidth Meter)

You can see the real-time bandwidth for all of the Firebox interfaces on the Bandwidth Meter tab. The Y axis (vertical) shows the traffic flow into and out of each interface, at the scale you select. The X axis (horizontal) shows the time. You can click any location on the chart to see more detailed information in a pop-up window about bandwidth use at that time. In addition to physical interfaces, the meter shows traffic on VLAN interfaces.
