-
-`dubbo-spring-boot-actuator` 提供 Production-Ready 特性 (比如 [健康检查](#health-checks),  [OPS 端点](#endpoints), and [外部化配置](#externalized-configuration)).

-
-
-## 目录
-

-
-## Maven 整合
-
-### 稳定版本
-
-`dubbo-spring-boot-actuator` 是可选模块，它不应该独立存在，需要与 `dubbo-spring-boot-starter` 并存方可工作正常。您可以直接增加到
-应用工程的 pom.xml 文件：
-
-
-```xml
-<dependencies>
-
-    ...
-
-    <!-- 功能特性 -->
-    <dependency>
-        <groupId>org.apache.dubbo</groupId>

-
-如果你需要尝试最新 `dubbo-spring-boot-actuator` 的特性，您可以自将[开发分支](../tree/0.1.x) 手动 Maven install 到本地 Maven 仓库。
-
-
-## 健康检查
-
-`dubbo-spring-boot-actuator` 实现了标准的 Spring Boot `HealthIndicator` , 它将聚合 Dubbo 相关的健康指标数据到 Spring Boot's `Health`
- ，并且 暴露在 `HealthEndpoint` ，它能够在 works MVC (Spring Web MVC) and JMX (Java Management Extensions) both if they are available.
-
-
-### Web Endpoint : `/health`

-
-假设 Spring Boot Web 应用没有指定 `management.port` 属性, 运行后，通过 Web 客户端访问 http://localhost:8080/health，HTTP 相应将会返回一个 JSON 格式的内容，如下所示:

-
-
-
-其中 `memory`, `load`,  `threadpool` and `server` 是 Dubbo 内建的 `StatusChecker`s，并且 Dubbo 允许应用程序扩展 `StatusChecker`'s SPI.
-
-默认情况, `memory` and `load` 将被添加到 Dubbo 的 `HealthIndicator` , 可以通过外部化配置覆盖默认值，请参考 [`StatusChecker`'s 默认值](#statuschecker-defaults).
-
-
-
-### JMX Endpoint : `healthEndpoint`
-
-
-`dubbo-spring-boot-actuator` 也将暴露健康检查的 JMX Endpoint，它的 `ObjectName` 为 `org.springframework.boot:type=Endpoint,name=healthEndpoint` ,
- 开发人员可以通过 JMX 代理工具 ,比如 `jconsole` 等：
-
-![](JMX_HealthEndpoint.png)
-
-
-
-### 内建 `StatusChecker`s
-
-
-Dubbo 内建 `StatusChecker` 实现定义在 `META-INF/dubbo/internal/com.alibaba.dubbo.common.status.StatusChecker` 文件中，内容如下 :
-
-```properties
-registry=com.alibaba.dubbo.registry.status.RegistryStatusChecker
-spring=com.alibaba.dubbo.config.spring.status.SpringStatusChecker
-datasource=com.alibaba.dubbo.config.spring.status.DataSourceStatusChecker
-memory=com.alibaba.dubbo.common.status.support.MemoryStatusChecker
-load=com.alibaba.dubbo.common.status.support.LoadStatusChecker
-server=com.alibaba.dubbo.rpc.protocol.dubbo.status.ServerStatusChecker
-threadpool=com.alibaba.dubbo.rpc.protocol.dubbo.status.ThreadPoolStatusChecker
-```
-
-
-
-The property key that is name of  `StatusChecker` can be a valid value of `management.health.dubbo.status.*` in externalized configuration.
-
-
-
-## Endpoints
-
-
-
-Actuator endpoint `dubbo` supports Spring Web MVC Endpoints :

-## Externalized Configuration
-
-
-
-### `StatusChecker` Defaults
-
-
-
-`management.health.dubbo.status.defaults` is a property name for setting names of `StatusChecker`s , its value is allowed to multiple-values , for example : 
-
-```properties
-management.health.dubbo.status.defaults = registry,memory,load
-```
-
-
-
-#### Default Value
-
-The default value is : 
-
-```properties
-management.health.dubbo.status.defaults = memory,load
-```
-
-
-
-### `StatusChecker` Extras
-
-
-
-`management.health.dubbo.status.extras` is used to override the [ [`StatusChecker`'s defaults]](#statuschecker-defaults) , the multiple-values is delimited by comma :
-
-```properties
-management.health.dubbo.status.extras = load,threadpool
-```
-
-
-
-### Health Checks Enabled
-
-
-
-`management.health.dubbo.enabled` is a enabled configuration to turn on or off health checks feature, its' default is `true`.
-
- If you'd like to disable health checks ,  you chould apply `management.health.dubbo.enabled` to be `false`:
-
-```properties
-management.health.dubbo.enabled = false
-```
-
-
-
-### Endpoints Enabled
-
-
-
-Dubbo Spring Boot providers actuator endpoint `dubbo` , however it is disable. If you'd like to enable it , please add following property into externalized configuration :
-
-```properties
-# Dubbo Endpoint enabled (default value is false)
-endpoints.dubbo.enabled = true
-```
-
-
-
-### Endpoints Sensitive
-
-Dubbo endpoints contain some sensitive information and significant opeations , thus it's sensitive , that means endpoints maybe protected and authorized if security resolved.
-
-
-
-If you consider it's fine to be public , you can add following property into externalized configuration :
-
-```properties
-# Dubbo Endpoint (default value is true)
-endpoints.dubbo.sensitive = false
-```
-
-> If Spring Security were resolved , configure more :
->
-> ```properties
-> management.security.enabled = false
-> ```
