Features

The graph will display the total of all servers, or the incoming/outgoing of a single server.
The number at the bottom (x-axis) simply means "Hours Ago". So the data on the right is the latest data.
The y-axis is mbps.
5 minute recording.
The data collected is real-time, generated from the network interface statistics. Very accurate recording using averages.
