流量统计插件

getty提供了简单的流量统计插件，可方便统计总的字节以及规定时间内的吞吐量

 AioServerStarter server = new AioServerStarter(8888);
        server.bossThreadNum(10).channelInitializer(new ChannelInitializer() {
            @Override
            public void initChannel(AioChannel channel) throws Exception {
                DefaultChannelPipeline defaultChannelPipeline = channel.getDefaultChannelPipeline();
                //添加统计插件
                ChannelTrafficShapingHandler channelTrafficShapingHandler=  new ChannelTrafficShapingHandler(10000)
                defaultChannelPipeline.addLast(channelTrafficShapingHandler);
                //获取总读取字节数
                channelTrafficShapingHandler.getTotalRead();
                defaultChannelPipeline.addLast(new DelimiterFrameDecoder(DelimiterFrameDecoder.lineDelimiter));
                defaultChannelPipeline.addLast(new StringDecoder());
                defaultChannelPipeline.addLast(new SimpleHandler());
            }
        });
        server.start();

构造方法

 //checkInterval为统计时间间隔，单位为毫秒
 ChannelTrafficShapingHandler(int checkInterval)

目前仅提供各通道总的读写字节数以及单位时间内的吞吐量
