Admin监控应用

Spring Boot提供的监控接口，例如：/health、/info等等，实际上除了之前提到的信息，还有其他信息业需要监控：当前处于活跃状态的会话数量、当前应用的并发数、延迟以及其他度量信息。下面我们来了解如何使用spring-boot-admin来监控我们的系统。

admin-server-ui

pom.xml配置:

<parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.4.3.RELEASE</version>    <relativePath/></parent><dependencyManagement>    <dependencies>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-dependencies</artifactId>            <version>Camden.SR5</version>            <type>pom</type>            <scope>import</scope>        </dependency>    </dependencies></dependencyManagement><dependencies>    <dependency>        <groupId>org.springframework.cloud</groupId>        <artifactId>spring-cloud-starter-eureka</artifactId>    </dependency>    <dependency>        <groupId>de.codecentric</groupId>        <artifactId>spring-boot-admin-server</artifactId>        <version>1.4.5</version>    </dependency>    <dependency>        <groupId>de.codecentric</groupId>        <artifactId>spring-boot-admin-server-ui</artifactId>        <version>1.4.5</version>    </dependency></dependencies>

application.properties配置:

spring.application.name=admin-uiinfo.version=@project.version@server.port=8080 eureka.client.serviceUrl.defaultZone=http://localhost:8888/eureka/

java代码:

@SpringBootApplication@EnableDiscoveryClient@EnableAdminServerpublic class AdminApplication {     public static void main(String[] args) {        SpringApplication.run(AdminApplication.class, args);    }}

logback-spring.xml配置:

<?xml version="1.0" encoding="UTF-8"?><configuration>    <include resource="org/springframework/boot/logging/logback/base.xml"/>    <jmxConfigurator/></configuration>

添加其他项目被监控

在被监控的服务pom.xml中增加：

<!--    spring-boot-admin-starter-client中包含的spring-boot-starter-actuator用于收集服务信息    <dependency>      <groupId>org.springframework.boot</groupId>      <artifactId>spring-boot-starter-actuator</artifactId>    </dependency>--><dependency>    <groupId>de.codecentric</groupId>    <artifactId>spring-boot-admin-starter-client</artifactId>    <version>1.4.5</version></dependency>

application.properties增加:

# 关闭安全访问management.security.enabled=false # 如果被监控的服务没有注册到服务中心，需要增加admin的地址# spring.boot.admin.url=http://localhost:8888

增加logback-spring.xml:

<?xml version="1.0" encoding="UTF-8"?><configuration>    <include resource="org/springframework/boot/logging/logback/base.xml"/>    <jmxConfigurator/></configuration>
