Discovering conversations between local devices and the Internet
The Internet Observer tool has three distinct tabs:
Internet Patrol—Internet Patrol permits you to examine established connections between local devices (e.g. stations) and the greater Internet.
IP Pairs (Matrix)—Similar to Internet Patrol, the IP Pairs (Matrix) permits you to examine established connections between local devices (e.g. stations) and the greater Internet.
IP Subprotocols—IP Subprotocols displays network traffic flow categorized by subprotocol, such as HTTP or SMTP.
Each tab of the Internet Observer tool can be customized. Specifically, you can change the layout of the in-focus tab by clicking View and selecting another. To make further customizations to each view, click the Settings button and a window appears.

The Statistics Settings tab of the Internet Observer Settings window is its most important tab. Notably, you can specify a specific TCP or UDP port to observe if desirable, and you can also configure which subprotocols are recognized by clicking Configure IP Application List.
Note: Changes made to the Statistics Settings tab are saved and shared by all modes (tabs) of the Internet Observer tool; however, changes made to any layout view (list, pair circle, etc.) are saved and used independently.
Internet Patrol tab
Internet Patrol displays MAC address to layer 3 IP address traffic. If the MAC address has an alias assigned, this text will be displayed instead of the true MAC address. Additionally, the IP addresses of the destination sites will be resolved using DNS. This view of your Internet traffic is most appropriate for local network traffic to and from the Internet, and for sites that use DHCP. Since DHCP changes IP addresses frequently, source IP addresses are not useful on DHCP sites for identification.
IP Subprotocols tab
IP Subprotocols display layer 3 IP addresses traffic flow broken-down by subprotocol. Subprotocols are defined in the setup dialog. Twenty-four (24) user-defined subprotocols can be created. Other indicates a protocol that did not match the criteria of the twenty-four user-defined protocols.
To discover conversations between local network devices and the Internet, use the Internet Observer tool.
On the Home tab, in the Statistics group, click Internet Observer.
