Info

Basic statistics 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. Information 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 3.3). 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). 272
20.2 Interface statistics Figure 20.5 Chart informing about average throughput at the interface 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. 273
