When started from the main menu and logging is enabled, the IP traffic monitor prompts you for a log file name. The default name is ip_traffic-n.log (where n is what instance of the traffic monitor this is (1, 2, 3, and so on). (e.g. if this is the first instance, the default file name will be ip_traffic-1.log.)
When started with the -i parameter, the log filename can be specified with the -L parameter. See the Command-line Parameters section above for more information.
On busy networks, the display may become cluttered with traffic you're not interested in. To control the traffic monitor's output, you can apply a filter. See Chapter 7, Filters for more information on IPTraf's filters.
At any time, you can press X or Q to return to the main menu (or back to the shell if the monitor was started with iptraf -i).
