springcloud 整合 springboot-admin 监控中心

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-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:

<?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>
