The Real-time bandwidth menu provides live monitoring of any router interface in graph form. Data are reset when the page first loads¹⁾, and the display draws gradually. The maximum display window is 10 minutes, and data resolution is 2 seconds. That means 10 minutes of data can be displayed at a time, and that data can be sampled every 2 seconds, at most. Only one interface at at a time can be displayed. Clicking on the interface name in any square displays the bandwidth of that interface. The interfaces available to be monitored will depend on the router hardware and configurations (for example, using a VPN or virtual wireless interfaces).

Some examples of FreshTomato interfaces are (may vary based on firmware release and hardware model):

• vlan2: Wired WAN port on the router
• vlan1: Wired LAN ports on the router
• eth0: All Ethernet ports on the router
• eth1: Wireless 2.4 GHz
• eth2: Wireless 5 GHz (if equipped)
• br0: The software bridge corresponding to vlan1, eth1, eth2. (What is commonly called LAN)

Avg. This applies a percentile to the image. This can show how a data point compares to the total distribution (graph) over time.

Max: Choosing Uniform scales graphs to the maximum value recorded on all interfaces. Choosing Per If (Per Interface) scales graphs based on data from one interface only.

Unit: kbit/KB, Mbit/MB - toggles between displaying volume in kilobits/Kilobytes (1,000) or megabits/Megabytes (1,000,000).

Display: Choosing Solid graphs bandwidth usage with a solid area, choosing Line graphs bandwidth with a single line representing maximum values.

Color: Switches between various pre-specified color schemes for the graph.

[reverse] : This reverses the graph's color scheme. For example, a device traced in blue is traced in orange and vice versa.

Cursor-Tracking Readout: Bandwidth graphs feature a a Cursor-Tracking Readout. When you move your mouse cursor over the graph, the graph displays the following at the top right corner:

• Day of Week
• Time
• Bandwidth usage.

These update as you move your mouse.

The Cursor-Tracking Readout disappears after 5 intervals: that is, 10 seconds in Real-Time, 10 minutes in Last 24 Hours, and so on.

Mouse-Click Readout: Bandwidth graphs also feature a Mouse-Click Readout: If you click on the graph, the date/time/bandwidth numbers will display beside the mouse cursor.

Note: Mouse-click readout is static. It does not update with graph movement or scaling.
