+=== Reactor Netty HttpServer
+
+If you're using Reactor Netty and would like to have your access logs instrumented you need to add the `io.projectreactor.netty:reactor-netty-http-brave` (this will work only for the Brave Tracer). Also add the following configuration to your project.
+
+[source,java,indent=0]
+-----
+import brave.http.HttpTracing;
+import reactor.netty.http.brave.ReactorNettyHttpTracing;
+
+@Configuration(proxyBeanMethods = false)
+class TraceNettyConfig {
+
+	@Bean
+	NettyServerCustomizer traceNettyServerCustomizer(ObjectProvider<HttpTracing> tracing) {
+		return server -> ReactorNettyHttpTracing.create(tracing.getObject()).decorateHttpServer(server);
