Thanks for the nice words! If you see anything missing, don't hesitate to create an issue about it on Github (https://github.com/loadimpact/k6). We're trying really hard to build the things people ask for. About CSV output though, we have JSON output with single request timings, see https://docs.k6.io/docs/results-output#section-json-output

Is JSON useful to you, or do you prefer CSV?

That looks like what I'm looking for, thanks! Is there documentation of the format of those JSON logs? CSV would probably be a useful addition just for ease of ingestion into analysis tools and databases.

Once I get a chance to test this out, I'll definitely report any issues through GH.

I'll update the docs with some info on the JSON format first thing on monday!

If you should happen to try out k6 in the meantime, most of the JSON contents should be recognizable/understandable just by looking at the output, if you know what metrics k6 collects (which is documented on docs.k6.io). You can try running with e.g. 2 VUs for 2 iterations, to get a tiny amount of output data but something that looks like a real load test: k6 run --vus 2 --iterations 2 --output json=output.json script.js
