The tool first traces all of your devices and lists them in a left-hand menu panel in the interface. You can switch between devices just by selecting a different IP address in the list. The main panel of the screen shows live traffic and distinguishes the applications sourcing each traffic flow with different colors. With this display, you can see all of the applications operating on the network simultaneously. That segmentation of traffic can also be switched to show the endpoints, domain or protocol that generates the traffic instead of the applications.
It can also compress the display to identify each active exchange, or conversation, being carried out on the network. The tool runs on Windows and it is only intended for quick checks.

Cloud-based network monitoring tools all operate a remote monitoring system. In order to get around network security, these remote monitoring tools usually require an agent service to be installed on the remote network. A typical network traffic monitor is able to identify traffic by application.
This is possible because specific applications communicate on specific ports. The source and destination port numbers are always written in the packet headers that carry network traffic. In Wireshark, the data from captured packets is broken down into three different sections. Each of these sections provides you with different information. These sections are:. These are the three areas where you need to look when monitoring packet captures.
It is important to note that Wireshark uses color-coding to help the user distinguish between captured packet types. When capturing data in Wireshark you will need to configure a capture filter to limit the information that you collect. To filter packets on Wireshark click the Filter box beneath the toolbar and enter TCP or another protocol you want to filter for.
You can also use the Bookmark icon on the left of the entry field to activate other popular filters. In addition, you can apply filters to filter data that has already been recorded. These are called Display filters. Related: How to conduct a network stability test.
