Load testing is hard, and the tools are not great. But why?
I agree that the popular load testing tools leave plenty to be desired, but have you given k6[1] a try? (Full disclosure: I'm one of the maintainers.)
Tests are written in JavaScript and there's support for HTTP, WebSockets and (unary) gRPC. You can easily script a combination of these protocols to mimic real world traffic.
Furthermore you can record a user flow with a browser extension[2] and convert the generated HAR file to a k6 script[3], which would give you an even closer real world scenario. The conversion is not perfect and depending on the service you might need to manually modify the script, but it would get you 90% of the way there.

What tools you use for http load testing?
Good morning what tool do you use to test your infra in terms of http load ? A tool that works, I tested : - https://github.com/tsenart/vegeta but it returns 0 errors or a http_net error from Golang - LOIC (Low Orbit Ion Canon) https://github.com/NewEraCracker/LOIC but the requests do not appear in my nginx logs and I feel no slowdown - Apache Jmeter https://jmeter.apache.org/ but I can't drop my infra and I have Java socket closed errors - K6 https://k6.io/ but I can't bring down my infra with - wrk https://github.com/wg/wrk no matter what parameter I put it doesn't make enough requests per second, I put the same parameters as on a tutorial and I don't get the same result...
