GUI con't.
This is the "Diagram Properties" window:

What's nice in both these windows is the sample diagram across the bottom which changes as you alter settings, to give you an idea of what the chosen diagram will look like. Finally, here's the "Settings" window:

Features
This program is very simple and its purpose explains most of its features - namely, monitoring network connections, statistics and speeds. What's more informative is to examine the features other programs like this don't have.
You can customize each graph's name, colors, text, and size (for diagrams other than tray icons). Multiple graphs can be active simultaneously, each monitoring specific components. The tray diagram can be split up into multiple tray icons, spanning a greater length of time. Units for data and speed can be customized - KB, MB, kbps, Mbps, etc, although the default "auto" setting chooses the most appropriate units. Each of the graphed parameters can be customized with respect to connection type. The program uses "Smart Filtering Technology". The following is a description from the program's help file:
"Using the Smart Filtering System you can measure the traffic of certain applications, such as email client, web browser, etc. This system is based on precise receiving/transmitting stream analysis which determines the type of connection. This method gives more reliable application detection than port number detection. When a port number is changed, port number detection is no longer accurate. On the Internet, where many applications use non-standard port numbers, Smart Filtering Technology is much more accurate. Alternately you can use standard filtering, which uses the Windows built-in library to find the sum of sent/received bytes. This method doesn't discriminate between types of traffic."
There are several types of diagrams, each of which can be customized:
- graph in tray
- tray icon, similar to Windows networking icon
- diagram window (scrolling larger diagram)
- diagram window, no text
- statistics window, text only
- invisible, gathers statistics data and writes them to a file
- Wi-Fi signal strength indicator
The types of traffic you can monitor are:
- web traffic (http)
- encrypted web traffic (https)
- file transfer traffic (ftp)
- Windows Networks traffic (netbios)
- Domain name resolving (domain)
- E-mail sending (smtp)
- E-mail receiving (pop3)
- E-mail receiving (imap)
- Usenet traffic (nntp)
- streaming audio and video (rtsp)
For each diagram, you can monitor one of the above, all the above, or a custom setting based on traffic type, protocol (TCP, UDP, ICMP, ARP), remote host, local and remote port numbers. All this can be specified by network adapter.
