20.2 Interface statistics
253
The period (2 hours or 1 day) can be selected in the Time interval box. The selected time range
is always understood as the time until now (“last 2 hours” or “last 24 hours”).
The xaxis of the chart represents time and the yaxis represents traffic speed. The xaxis is
measured accordingly to a selected time period, while measurement of the yaxis depends on
the maximal value of the time interval and is set automatically (bytes per second is the basic
measure unit — B/s).
Select an option for Picture size to set a fixed format of the chart or to make it fit to the
Administration Console screen.
The legend above the graph shows the sampling interval (i.e. the time for which a sum of
connections or messages is counted and is displayed in the graph).
Example
Suppose the 1 day interval is selected. Then, an impulse unit is represented by 5 minutes.
This means that every 5 minutes an average traffic speed for the last 5 minutes is recorded in
the chart.
