Programs to view process traffic on Ubuntu?

Question

linux

You need to see the traffic of the running process on Ubuntu. What are the programs with clear UI/GUI? Preferably something as simple and intuitive as Net Monitor in Chrome Dev Tools

Answer 1

Wireshark

Answer 2

If the process is not started yet, you can start it as a new process and monitor it using the following
strace -f -e trace=network -s 10000 ;
If the process is already started and you know its PID you can use the following
strace -f -e trace=network -s 10000 -p ;
Then Wireshark
