measure latency when sending TCP packets

Question

I have two redhat 7 virtual machiens deployed in Azure.

I am looking for a tool which enable me to measure throughput, latency and jitter (min max and average), when sending TCP and UDP packets from one vm to another.

I tried to use 'iperf3' but unfortunately, I do not get latancy and jitter results when transmitting TCP packets:

Is there a way to get latancy and jitter results using 'iperf3' command, or can you recommand other tool to use?

Thanks for the help

You may like to use mtr, it measures round-trip latency to each hop in the path using ICMP, TCP or UDP. E.g.:

$ mtr --report-wide --show-ips --tcp --port 443 ya.ru

Without --report-wide is runs in interactive mode.
