JVMService实现了BootService及Runnable接口,其prepare方法创建了JVMMetric类型的LinkedBlockingQueue,以及Sender,并往GRPCChannelManager添加了该Sender;其boot方法注册了collectMetricFuture、sendMetricFuture两个调度任务,调度间隔都是1秒;其shutdown方法执行collectMetricFuture.cancel(true)及sendMetricFuture.cancel(true);其ru...

2. 与此对应的,skywalking对于自定义指标的metrics的支持很差 也就是说,如果想要实现一些自定义的指标,比如:每日到达网站的VIP用户数和VIP行为数据,skywalking就支持的很不好(注:新版本的skywalking支持接入prometheus的自定义指标,参考:SkyWalking 8.4 provides infrastructure monitoring | Apache SkyWalking); ...

skywalking支持dubbo,SpringCloud,SpringBoot集成,代码无侵入,通信方式采用GRPC,性能较好,实现方式是java探针,支持告警,支持JVM监控,支持全局调用统计等等,功能较完善。 1.2 如何选择 1.2.1 与zipkin相比 Skywalking相比于zipkin还是有很大的优势的,如下: skywalking采用字节码增强的技术实现代码无侵入,zipKin代码侵入性比较高...
