Dubbo高并发与分布式

Dubbo剖析-监控平台的搭建与使用

2018-03-16  本文已影响202人  阿里加多

一、前言

dubbo-monitor主要用来统计服务的调用次调和调用时间的监控中心，服务消费者和提供者，在内存中累计调用次数和调用时间，定时每分钟发送一次统计数据到监控中心，监控中心则使用数据绘制图表来显示。

二、dubbo-monitor-simple的搭建

在该目录执行mvn clean package -Dmaven.test.skip=true会生成如下结果：

进入/Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target
目录，会发现生成了dubbo-monitor-simple-2.5.10-assembly.tar.gz：

其中dubbo.registry.address=zookeeper://127.0.0.1:2181设置注册中心地址，这里设置为zk的地址

其中dubbo.protocol.port=7070，为monitor提供的远程服务监听端口，服务提供者和消费者会调用这个端口提供的服务，发送统计信息到monitor

dubbo.charts.directory和dubbo.statistics.directory为monitor本地存放的监控数据文件的位置

dubbo.jetty.port=8081 设置jetty容器的监听地址，类似于tomcat的8080端口，这里设置为8081

至此monitor启动了访问http://127.0.0.1:8081/ 会出现下面界面：

三、dubbo-monitor-simple的使用

3.2 服务查看

3.3 注册中心查看

3.4 调用数据统计

四、总结

dubbo-monitor也不是使用dubbo搭建分布式系统必须的组件，但是它用来统计服务的调用次调和调用时间的监控中心，这些数据有助于系统运维和调优。
