The Bandwidth - Real-Time menu shows 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, with 2-second data resolution. Ten minutes of data can be displayed at a time, with data sampled at most, every 2 seconds.

Only one interface can be displayed at a time. Clicking on the interface name in any square displays the bandwidth of that interface.

The interfaces available to be monitored depend on your hardware and configuration (for example, using a VPN or VWLAN interface).

Some possible FreshTomato interfaces are (depending on release/mode):

• vlan2: The wired WAN port on the router
• vlan1: The wired LAN ports on the router
• eth0: All Ethernet ports on the router
• eth1: The Wireless 2.4 GHz radio
• eth2: The wireless 5 GHz (if equipped) radio
• br0: The software bridge corresponding to vlan1, eth1, eth2. (or “The LAN”)

Avg. applies a percentile to the image. This shows how a data point compares to the total distribution over time.

Max:

• Uniform - this scales graphs to the maximum value recorded on all interfaces.
• Per If (Per Interface) - this scales graphs based on data from one interface only.

Unit:

• kbit/KB - toggles between displaying volume in kilobits/Kilobytes (1,000).
• Mbit/MB: toggles display volume to be expressed in megabits/Megabytes (1,000,000).
• 
  

Display:

• Solid - graphs bandwidth usage with a solid area.
• Line - graphs bandwidth using a single line representing maximum values.
• 
  

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

[reverse] : reverses the graph's color scheme. A device traced in blue is traced in orange and vice versa.

Cursor-Tracking Readout: Bandwidth graphs have a a Cursor-Tracking Readout. Moving your mouse cursor over the graph causes it to display the following at the top right:

• Day of the 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 have a Mouse-Click Readout: Clicking on the graph will make the date/time/bandwidth numbers display beside the mouse cursor. This function is static. It does not update with graph movement or scaling.
