8.20. Flow Graph

The Flow Graph window shows connections between hosts. It displays the packet time, direction, ports and comments for each captured connection. You can filter all connections by ICMP Flows, ICMPv6 Flows, UIM Flows and TCP Flows. Flow Graph window is used for showing multiple different topics. Based on it, it offers different controls.

Each vertical line represents the specific host, which you can see in the top of the window.

The numbers in each row at the very left of the window represent the packet time. You can change the time format in the → . If you change the time format, you must relaunch the Flow Graph window to observe the time in a new format.

The numbers at the both ends of each arrow between hosts represent the port numbers.
