Reset interface statistics
This option resets statistics of the selected interface. It is available only if the mouse
pointer is hovering an interface at the moment when the context menu is opened.
Refresh
This option will refresh the information on the Interface Statistics tab immediately. This
function is equal to the function of the Refresh button at the bottom of the window.
Auto refresh
Settings for automatic refreshing of the information on the Interface Statistics tab. Infor-
mation can be refreshed in the interval from 5 seconds up to 1 minute or the auto refresh
function can be switched off (No refresh).
Manage Columns
Use this option to select and unselect items (columns) which will (not) be displayed in the
table (see chapter
).
Remove interface statistics
This option removes the selected interface from the statistics. Only inactive interfaces
(i.e. disconnected network adapters, hung-up dial-ups, disconnected VPN tunnels or VPN
servers which no client is currently connected to) can be removed. Whenever a removed
interface is activated again (upon connection of the VPN tunnel, etc.), it is added to the
statistics automatically.
Graphical view of interface load
The traffic processes for a selected interface (transfer speed in B/s) and a specific time period
can be viewed in the chart provided in the bottom window of the Interface statistics tab. Use
the Show details / Hide details button to show or hide this chart (the show mode is set by
default).
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 x axis of the chart represents time and the y axis represents traffic speed. The x axis is
measured accordingly to a selected time period, while measurement of the y axis 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).
