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>

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Camden.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>

<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>

<dependency>
<groupId>de.codecentric</groupId>
<artifactId>spring-boot-admin-server</artifactId>
<version>1.4.5</version>

<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
[email protected]@
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>
