Can we also trace the netty client and server?

[duwupeng]

@Xylus Can we also trace the netty client and netty server?

 Server: 
 @Override
    public void start() {
        LOGGER.info("Bind Local Port {} [Netty]", port);

        new Thread("NettyContainer-Thread") {
            @Override
            public void run() {
                try {
                    bootstrap = new ServerBootstrap();

                    bootstrap.group(bossGroup, workerGroup)
                            .channel(NioServerSocketChannel.class)
                            .childHandler(new ChannelInitializer<SocketChannel>() {
                                @Override
                                protected void initChannel(SocketChannel ch) throws Exception {
                                    ch.pipeline().addLast(new IdleStateHandler(15, 0, 0), new SoaDecoder(), new SoaIdleHandler(), new SoaServerHandler(ProcessorCache.getProcessorMap()));
                                }
                            })
                            .option(ChannelOption.SO_BACKLOG, 1024)
                            .option(ChannelOption.ALLOCATOR, PooledByteBufAllocator.DEFAULT)//重复利用之前分配的内存空间(PooledByteBuf -> ByteBuf)
                            .childOption(ChannelOption.SO_KEEPALIVE, true)
                            .childOption(ChannelOption.ALLOCATOR, PooledByteBufAllocator.DEFAULT);

                    // Start the server.
                    ChannelFuture f = bootstrap.bind(port).sync();

                    // Wait until the connection is closed.
                    f.channel().closeFuture().sync();
                } catch (InterruptedException e) {
                    LOGGER.error(e.getMessage(), e);
                } finally {
                    workerGroup.shutdownGracefully();
                    bossGroup.shutdownGracefully();
                }
            }
        }.start();
    }```


Client: 

  b = new Bootstrap();
        b.group(workerGroup);
        b.channel(NioSocketChannel.class);
        b.option(ChannelOption.SO_KEEPALIVE, true);
        b.option(ChannelOption.ALLOCATOR, PooledByteBufAllocator.DEFAULT);
        b.handler(new ChannelInitializer<SocketChannel>() {
            @Override
            public void initChannel(SocketChannel ch) throws Exception {
                ch.pipeline().addLast(new IdleStateHandler(readerIdleTimeSeconds, writerIdleTimeSeconds, allIdleTimeSeconds), new SoaDecoder(), new SoaIdleHandler(), new SoaClientHandler(callBack));
            }
        });
        return b;

UP,,,I was looking forward to a netty trace support also :))

[jiaqifeng]

Pinpoint supports Jetty which using Netty. The key point is that Netty is a transport lib, you can not find a common trace start entry in it, and for tcp and udp there are no common way to insert the span info into the packet to continue the trace too.

[jiaqifeng]

What I mean is that there could not be a common plugin for netty but you could write a plugin for your app in a level above netty.

hello,I want to monitor the trace of netty progresses；how can I do for it！

Hello, is there any way to monitor the trace of Netty ServerBootstrap port and application
