You can actually enable DEBUG logging for Netty and Reactor-Netty related to see full picture of what's happening. You could play with the below and see what you want and don't. That was the best I could.

reactor.ipc.netty.channel.ChannelOperationsHandler: DEBUG
reactor.ipc.netty.http.server.HttpServer: DEBUG
reactor.ipc.netty.http.client: DEBUG
io.reactivex.netty.protocol.http.client: DEBUG
io.netty.handler: DEBUG
io.netty.handler.proxy.HttpProxyHandler: DEBUG
io.netty.handler.proxy.ProxyHandler: DEBUG
org.springframework.web.reactive.function.client: DEBUG
reactor.ipc.netty.channel: DEBUG
