  • skywalking的rocketmq-plugin定义了4个增强，分别是ConsumeMessageConcurrentlyInstrumentation、ConsumeMessageOrderlyInstrumentation、MQClientAPIImplInstrumentation、SendCallbackInstrumentation

ConsumeMessageConcurrentlyInstrumentation

  • ConsumeMessageConcurrentlyInstrumentation继承了ClassInstanceMethodsEnhancePluginDefine，它使用org.apache.skywalking.apm.plugin.rocketMQ.v4.MessageConcurrentlyConsumeInterceptor增强org.apache.rocketmq.client.consumer.listener.MessageListenerConcurrently的consumeMessage方法

AbstractMessageConsumeInterceptor

skywalking-6.6.0/apm-sniffer/apm-sdk-plugin/rocketMQ-4.x-plugin/src/main/java/org/apache/skywalking/apm/plugin/rocketMQ/v4/AbstractMessageConsumeInterceptor.java

public abstract class AbstractMessageConsumeInterceptor implements InstanceMethodsAroundInterceptor {

    public static final String CONSUMER_OPERATION_NAME_PREFIX = "RocketMQ/";

    @Override
    public final void beforeMethod(EnhancedInstance objInst, Method method, Object[] allArguments,
        Class<?>[] argumentsTypes,
        MethodInterceptResult result) throws Throwable {
        List<MessageExt> msgs = (List<MessageExt>)allArguments[0];

        ContextCarrier contextCarrier = getContextCarrierFromMessage(msgs.get(0));
        AbstractSpan span = ContextManager.createEntrySpan(CONSUMER_OPERATION_NAME_PREFIX + msgs.get(0).getTopic() + "/Consumer", contextCarrier);

        span.setComponent(ComponentsDefine.ROCKET_MQ_CONSUMER);
        SpanLayer.asMQ(span);
        for (int i = 1; i < msgs.size(); i++) {
            ContextManager.extract(getContextCarrierFromMessage(msgs.get(i)));
        }

    }

    @Override public final void handleMethodException(EnhancedInstance objInst, Method method, Object[] allArguments,

        }

        return contextCarrier;

  • AbstractMessageConsumeInterceptor实现了InstanceMethodsAroundInterceptor接口，其beforeMethod方法执行ContextManager.extract(getContextCarrierFromMessage(msgs.get(i)))；其handleMethodException方法执行ContextManager.activeSpan().errorOccurred().log(t)

        }
        ContextManager.stopSpan();

  • ConsumeMessageOrderlyInstrumentation继承了ClassInstanceMethodsEnhancePluginDefine，它使用org.apache.skywalking.apm.plugin.rocketMQ.v4.MessageOrderlyConsumeInterceptor增强org.apache.rocketmq.client.consumer.listener.MessageListenerOrderly的consumeMessage方法

broker HA依托于Dledger，Deldger是阿里参与openmessage 里面的一个子项目，目前star呵呵，如果要生产需要仔细评估测试。 实现方式是在MessageStore里面进行了修改，通过增加一个commitlog类及HA切换，要注意默认模式下Slave是会写commitlog，而Dledger只有master写。 而MessageStorePlugin 是rocketmq用...

背景 笔者所在的业务线，最初化分为三个服务，由于业务初期业务复杂度相对简单，三个业务服务都能很好的独立完成业务功能。 随着产品迭代，业务功能越来越多后慢慢也要面对高并发、业务解耦、分布式事务等问题，所以经过团队内部讨论，引入 RocketMQ 消息中间件来更好的处理业务。 由于公司内部业务线部署相互独立，我们业务线对引入 RocketMQ 的需求也比较急切，所以打算自己搭建一套高可用的 RocketMQ 集群，同时对于自建的 RocketMQ 集群需要如下特性： 高可用 高并发 可伸缩 海量消息 命名服

3.3 Skywalking常用插件 3.3.1 配置覆盖 在之前的案例中，我们每次部署应用都需要复制一份agent，修改其中的服务名称，这样显得非常麻 烦。可以使用Skywalking提供的配置覆盖功能通过启动命令动态指定服务名，这样agent只需要部署一 份即可。Skywalking支持的几种配置方式： 系统配置（System properties) 使用 skywalking. + 配置文件中的配置名作为系统配置项来进行覆盖. 为什么需要添加前缀? agent的系统配置和环境与目标应用共享，所以

skywalking-agent自定义插件

SkyWalking 插件的工作机制主要基于 Java Agent，它会在应用启动时自动附加到目标应用上。插件主要实现方法拦截（Method Intercept），即在指定的方法执行之前、之后或者发生异常时进行操作，以便收集监控数据。增强类定义（Enhancement Class）：指定需要增强的目标类。方法拦截器（Method Interceptor）：定义拦截的逻辑，比如调用链的开始、结束、异常捕获等。

DataCarrier 是轻量级，嵌入式，高流通量，发布订阅模式的 MQ. 特点 订阅式 MQ. 支持多商家与多用户。 轻量级与嵌入式，jdk1.6.中的迷你Java库。 高流通量， 用于 Sky-Walking APM。 产生异步数据。 使用简单，简洁 API. 随着Sky-Walking版本的研发，各个模块中存在大量的内存级，非严格FIFO 发布/订阅队列的需求。所以，我们新建项目DataCarrier：一个轻量级的、嵌入式、高速处理的发布订阅队列库。 该项目立足于jdk1.6，提供更广泛的代码
