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.bootgroupId>
    <artifactId>spring-boot-starter-parentartifactId>
    <version>1.4.3.RELEASEversion>
    <relativePath/>

            <version>Camden.SR5version>

        <artifactId>spring-boot-admin-server-uiartifactId>
        <version>1.4.5version>
    dependency>
dependencies>

• 注意版本号（1.5.2+1.5.7）
  

application.properties配置:

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

java代码:

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

logback-spring.xml配置:

"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：

<dependency>
    <groupId>de.codecentricgroupId>
    <artifactId>spring-boot-admin-starter-clientartifactId>
    <version>1.4.5version>
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:

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