How to view the traffic of a specific program?

Question

Traffic analysis

Hello, how can I view the traffic of a specific program / process in Windows. I had a program like this for a long time, now I can not find it. Tried all known sniffers.
PS I’ll clarify not just to see the activity and amount of traffic, but to view the traffic itself

Answer 1

If under Windows, then the most convenient than used - HTTP Analyzer
Intercepts both HTTP and HTTPS. specific application. It can save traffic to a file, so that later it can be opened and analyzed slowly.
Minus - a paid program. But there are cracks, if the moral side of the issue does not confuse.

Answer 2

Have you tried Wireshark?
