Dubbo剖析-监控平台的搭建与使用

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

  • 在服务提供方和消费方需要配置如下:
    <dubbo:monitor protocol=”registry”/>
    protocol为”registry”,表示服务提供方和消费方从注册中心发现监控中心(monitor)地址。
  • 下载源码
    在 https://github.com/alibaba/dubbo/tree/2.5.x 下载dubbo的源码
  • 解压源码,进入dubbo-2.5.x 目录,内容如下:

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:

  • 解压dubbo-monitor-simple-2.5.10-assembly.tar.gz,修改进入dubbo-monitor-simple-2.5.10/conf/dubbo.properties:

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

  • 进入dubbo-monitor-simple-2.5.10/bin,执行sh start.sh启动monitor

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

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。
