Dubbo：搭建监控中心(dubbo-monitor-simple)_dubbo monitor

Dubbo-Monitor介绍

1. Dubbo-Monitor主要用来统计服务的调用次数和调用时间，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。
2. Dubbo-Monitor挂掉不会影响到Consumer和Provider之间的调用，所以用于生产环境不会有风险。 
3.  配置好了之后可以结合admin管理后台使用，可以清晰的看到服务的访问记录、成功次数、失败次数等…..
4. Simple Monitor采用磁盘存储统计信息，请注意安装机器的磁盘限制，如果要集群，建议用mount共享磁盘。

监控服务提供方和消费方

需要在服务提供方和消费方增加连接配置中心的配置来实现监控

在服务提供方和消费方的配置文件中添加如下代码

  <!-- 连接监控中心 -->
    <dubbo:monitor protocol="registry"></dubbo:monitor>
    <!-- 
      <dubbo:monitor address="127.0.0.1:7070"></dubbo:monitor> 
    -->

启动Dubbo-Monitor

进入\dubbo-monitor-simple-2.5.10-assembly\dubbo-monitor-simple-2.5.10\bin

启动:

./bin/start.sh  （windows系统是/bin/start.bat）

Dubbo-Monitor常用命令

启动:

./bin/start.sh  （windows系统是/bin/start.bat）

停止:

./bin/stop.sh

重启:

./bin/restart.sh

调试:

./bin/start.sh debug

系统状态:

./bin/dump.sh

总控入口:

./bin/server.sh start
./bin/server.sh stop
./bin/server.sh restart
./bin/server.sh debug
./bin/server.sh dump

Dubbo-Monitor

访问 http://192.168.60.207:8099

可以服务查看，应用程序查看，调用情况统计；

可以看到服务提供的名称（Service Name），配置的提供者的名称（Application），提供者的数量（Providers(2)），消费者的数量（ Consumers(3)），统计（Statistics） 和 图表（Charts）。

 　  1.点击 Providers(1)，可以看到提供者的详细信息，即提供者的URL

　　2.点击Consumers(1)，可以看到消费者的详细信息，即消费者的URL

　　3.点击Statistics，成功的次数，失败的次数，平均花费的时间，最大花费的时间，并发的次数。

　　4.点击Charts，可以看到请求和响应的图表。
 

 

Dubbo-Monitor图表不显示

1.可能不会自动创建monitor文件夹，需要在${user.home}目录下创建monitor目录

2.需要在服务端配置<dubbo:monitor protocol="registry"/>

3.在消费端配置<dubbo:monitor protocol="registry"/>
