Description

Hi I made a GUI for iperf 2 in Powershell: https://github.com/ili101/PPerf

I want to add iperf 3 support but iperf 3 don't have a parseable real time output option

iperf 2 have CSV output iperf 3 have JSON output but it's only updates at the end

I don't think JSON can support real time updates because of it's structure, probably why you are updating it only at the end.

Can you add CSV support or something with similar functionality?

Thank you

Research direction
Review iperf3's current output implementation in the src/iperf output.c file. Understand how JSON output is generated and sent at the end of a test. Compare with iperf2's CSV output that provides incremental updates. Consider implementing an incremental JSON format (JSON lines) or adding CSV support. Check any existing discussions in the comments for additional context (e.g., whether maintainers had concerns about JSON streaming). No linked PRs were found, so this is an open feature request.
