Project Description
Network Monitor 3.3 introduces the Experts menu. This feature allows you to run external analysis tools on an open capture file.

This page is points you to these useful “Experts” for your data analysis needs within Network Monitor. Also provided here is the Expert SDK. More information on Experts can be found here.

Experts can only be invoked from Network Monitor 3.3 Beta and later versions. To install the latest version of Network Monitor please click here. To install an Expert, download the appropriate MSI for your platform from one of the following Expert Download pages. Then, on any new capture you open with Network Monitor, you will see the new Expert available to run on your capture. Experts should also provide specific help on their usage from within the Experts menu.

See our Downloads tab for more information on the Expert SDK. This SDK contains examples as well as reusable code for parsing the command line and building expert MSIs.
