[Install the simple registry](admin-guide-install-manual#Install the simple registry)

0. export a simple monitor service to the registry: (If you use the installer, you don't need to write this configuration yourself. if you implement the monitor service yourself，need it)

   <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">
   
   <!-- configuration of current application -->
   <dubbo:application name="simple-monitor" />
   
   <!-- connection address of the registry -->
   <dubbo:registry address="127.0.0.1:9090" />
   
   <!-- protool configuration of exposed services -->
   <dubbo:protocol port="7070" />
   
   <!-- configuration of certain exposed service -->
   <dubbo:service interface="com.alibaba.dubbo.monitor.MonitorService" ref="monitorService" />
   
   <bean id="monitorService" class="com.alibaba.dubbo.monitor.simple.SimpleMonitorService" />
   </beans>
   

1. Discovery the monitor service int the registry:

   <dubbo:monitor protocol="registry" />
   

   or

   dubbo.properties

   dubbo.monitor.protocol=registry
   

2. Export a simple monitor service ，but don‘t register it to th registry: (If you use the installer, you don’t need to write this configuration yourself. if you implement the monitor service yourself，need it)

   <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:dubbo="http://dubbo.apache.org/schema/dubbo"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://dubbo.apache.org/schema/dubbo http://dubbo.apache.org/schema/dubbo/dubbo.xsd">
   
   <!-- configuration of current application -->
   <dubbo:application name="simple-monitor" />
   
   <!-- protool configuration of exposed service -->
   <dubbo:protocol port="7070" />
   
   <!-- configuration of exposed service -->
   <dubbo:service interface="com.alibaba.dubbo.monitor.MonitorService" ref="monitorService" registry="N/A" />
   
   <bean id="monitorService" class="com.alibaba.dubbo.monitor.simple.SimpleMonitorService" />   
   </beans>
   

3. connected to the monitor service straightly

   <dubbo:monitor address="dubbo://127.0.0.1:7070/com.alibaba.dubbo.monitor.MonitorService" />
   

   or：

   <dubbo:monitor address="127.0.0.1:7070" />
   

   or：

   dubbo.properties

   dubbo.monitor.address=127.0.0.1:7070
