Hey there!)
There's some change that, imho, is inconsistent with the underlying logic. In the past, WebSocket had its own logger, making it convenient and easy to filter and separate logs for HTTP, WebSocket, SSE, and anything else.
Now HTTP and WebSocket are combined together, whereas other protocols, such as SSE, are separated:
<logger name="io.gatling.http.action.sse.fsm" level="DEBUG" />
#4471

Could you please consider this change?
