Status Information Figure 19.6 Information on selected host and user — traffic histogram Select an item from the Time interval combo box to specify a time period which the chart will refer to (2 hours or 1 day). 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). This chart includes volume of transferred data in the selected direction in certain time intervals (depending on the selected period). The green curve represents volume of incoming data (download) in a selected time period, while the area below the curve represents the total volume of data transferred in the period. The red curve and area provide the same information for outgoing data (upload). Below the chart, basic statistic information, such as volume of data currently transferred (in the last interval) and the average and maximum data volume per an interval, is provided. Select an option for Picture size to set a fixed format of the chart or to make it fit to the Administration Console screen. 19.2 Network connections overview In Status → Connections, all the network connections which can be detected by Kerio Control include the following: • client connections to the Internet through Kerio Control • connections from the host on which Kerio Control is running 258
19.2 Network connections overview • connections from other hosts to services provided by the host with WinRoute • connections performed by clients within the Internet that are mapped to services running in LAN Kerio Control administrators are allowed to close any of the active connections. Note: 1. Connections among local clients will not be detected nor displayed by Kerio Control. 2. UDP protocol is also called connectionless protocol. This protocol does not perform any connection. The communication is performed through individual messages (so-called datagrams). Periodic data exchange is monitored in this case. Figure 19.7 Overview of all connections established via Kerio Control One connection is represented by each line of the Connections window. These are network connections, not user connections (each client program can occupy more than one connection at a given moment). The columns contain the following information: Traffic rule Name of the WinRoute traffic rule (see chapter 7) by which the connection was allowed. Service Name of transmitted service (if such service is defined in Kerio Control — see chapter 15.3). If the service is not defined in Kerio Control, the corresponding port number and protocol will be displayed instead (e.g. 5004/UDP). 259
