I'm using Nginx as WebSocket proxy and trying to set up the metric that will show me how quick gateway can establish new connections. Unfortunately, looks like when I parse logs I have only "response_time" that in the case of WebSockets will be better to call "connection time". Any ideas how can I get time between GET request and 101 response?<br></div>
