是Alibaba的開源項目，用於監控在dubbo框架下接口暴露，註冊情況，也可以看接口的調用明細，調用時間等。而且監控中心掛掉並不會影響生成者和消費者。

二. 安裝dubbo-simple-monitor

1. 下載源碼（托管在github上）

~]# wget https://github.com/alibaba/dubbo/archive/dubbo-2.6.0.zip
~]# unzip dubbo-2.6.0.zip
~]# cd dubbo-dubbo-2.6.0/

2. 安裝依賴

~]# yum -y install java-1.8.0-openjdk maven

maven: 用於編譯dubbo-simple-monitor
jdk: dubbo-simple-monitor是java語言所寫，故需要jdk

3. 編譯dubbo-simple-monitor

dubbo-dubbo-2.6.0]# cd dubbo-simple/dubbo-monitor-simple/
dubbo-monitor-simple]# mvn clean install

編譯成功後的目標文件為：target/dubbo-monitor-simple-2.6.0-assembly.tar.gz

4. 修改配置文件

我們使用dubbo-monitor-simple-2.6.0-assembly.tar.gz啟動程序，因為還有一些配置需要修改

target]# tar xf dubbo-monitor-simple-2.6.0-assemble.tar.gz -C /usr/local
target]# cd /usr/local
local]# vim dubbo-monitor-simple-2.6.0/conf/dubbo.properties

dubbo.jetty.port : 服務啟動後訪問的端口

5. 啟動服務

dubbo-monitor-simple-2.6.0]# bin/start.sh

6.訪問服務

查看服務調用情況

三. 出現的錯誤

1. 出現的問題

訪問是無法看到圖

2. 解決

• dubbo-simple-monitor配置文件中dubbo.jetty.directory中指明的目錄需要手動創建
• 我們需要監控的服務在配置dubbo時要加入<dubbo:monitor protocol="registry"/>這項配置
