SpringCloud（Finchley.RELEASE）基於springboot 2.X微服務監控平臺（Springboot Admin 2.X）（三）

Springboot Admin 是用於管理監控springboot 程序。Springboot Admin 分爲admin-server 和 admin-client兩個端。client端向server端註冊，也可以通過springcloud的eureka進行註冊，springboot admin2 纔有VUE.js重新編寫了頁面，不再是 admin 1.X採用的AngularJS編寫的前端頁面。監控的內容包括 actuator ,turbine, jmx , logleve

下面介紹兩種監控的實現方式，1）通過client端向server端註冊， 2）二通過eureka進行註冊

1、通過client端向server端註冊

首先創建一個名字爲admin-service的springboot項目， pom中加入如下依賴包

        </plugins>
    </build>

</project>

配置文件如下application.yml

server:
  port: 8761


spring:
  application:
    name: admin-service
  output:
    ansi:
      enabled: always
  boot:
    admin:
    #監控的斷點有哪些
      probed-endpoints: health, env, etrics, threaddump:dump, httptrace:trace,jolokia, info, logfile, refresh, flyway, liquibase, heapdump, loggers, auditevents
      #配置郵件監控
      notify:
        mail:
          to: 接收郵件的郵箱
          enabled: true  
          template: "classpath:/META-INF/spring-boot-admin-server/mail/status-changed.html"   --郵件模板
          from: 發送郵件的郵箱

  mail:
    host: smtp.qq.com
    username: [email protected]
    password: 郵箱的授權碼
    properties:
      mail:
        smtp:
          auth: true
          starttls:
            enable: true
            required: true

logging:
  file: "logs/boot-admin-sample.log"
info:
  version: 1.0.0

3、然後在application的啓動類中加入@EnableAdminServer的註解，即可，springboot admin的程序搭建完成，現在搭建client，client相對簡單，只要你的程序是基於springboot即可，只需修改pom文件和application.yml這兩個即可。

4、在想要監控的程序的pom.xml文件中增加如下依賴

<dependency>
			<groupId>de.codecentric</groupId>
			<artifactId>spring-boot-admin-starter-client</artifactId>
			<version>2.0.1</version>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
		<dependency>
			<groupId>org.jolokia</groupId>
			<artifactId>jolokia-core</artifactId>
		</dependency>

5、在appliance.yml文件中加入如下配置

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: always
    logfile:
      enabled: true

以及

spring:
    application:
      name: transfer-service-dev
    boot:
      admin:
        client:
          url: http://localhost:8761

6、分別啓動demo-service和admin-service ,在瀏覽器中輸入localhost:8761，就能看到admin的面板了
