@Sharable public abstract class HttpServerStatisticsHandler extends SimpleChannelInitializer<io.netty.channel.Channel>
An abstract handler which may be used to examine latencies in the Netty4 HTTP request processing. It is intended to be placed immediately after HttpServerCodec or BasicHttpServerCodec handlers. When the BasicHttpServerCodec is used, the request start time is the time when the first line of the request containing the URI was received. Extend this class, overriding the complete(Stats) method to process the HttpServerStatisticsHandler.Stats objects. The instance is sharable. 
   final HttpServerStatisticsHandler _stats = new HttpServerStatisticsHandler() {
     &at;Override
     protected void complete(Stats stats) {
       ...
     }
   };

   final ChannelHandler _initialization = new ChannelInitializer<Channel>() {
     &at;Override
     protected void initChannel(Channel ch) {
       ChannelPipeline p = ch.pipeline();

       ...

       p.addLast("http-server-codec", new HttpServerCodec());
       p.addLast("http-server-stats", _stats);

       ...
     }
   }
