Spring Cloud实战(三)-监控中心_springcloud monitor

接着上一篇 Spring Cloud实战(二)-注册中心 现在开始搭建监控中心

一.监控中心monitor-server

1.添加spring-boot-admin版本控制到cloud-action的pom.xml

2.pom.xml

3.application.yml

spring:
  application:
    name: monitor-server
  profiles:
    active: single
#监控配置
management:
  endpoints:
    web:
      exposure:
        include: "*" #公开所有端点 对于生产,您应该仔细选择要公开的端点.
  endpoint:
    health:
      show-details: always
  info:
    env:
      enabled: true
---
#单机版
spring:
  config:
    activate:
      on-profile: single
server:
  port: 2222 #当前eureka-server服务的端口号
eureka:
  instance:
    lease-renewal-interval-in-seconds: 30 #服务续约(心跳检测)时间,默认30秒
    lease-expiration-duration-in-seconds: 90 #服务剔除时间,默认90秒
    health-check-url-path: /actuator/health
    metadata-map:
      startup: ${random.int}    #需要在重启后触发信息和端点更新
  client:
    service-url:
      defaultZone: http://localhost:1111/eureka/ #eureka-client设置eureka-server的地址

4.MonitorApplication.java

package com.example.monitor;
 
import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
/**
 * @author 86188
 */
@SpringBootApplication
@EnableAdminServer //开启监控服务
public class MonitorApplication {
    public static void main(String[] args) {
        SpringApplication.run(MonitorApplication.class, args);
    }
}

5.测试

java -jar monitor-server-0.0.1-SNAPSHOT.jar

 可以看到监控信息非常详细

特别说明:

实际开发中监控模块完全可以和eureka注册中心放在一块,只需要配置spring.boot.admin.context-path 以便 Spring Boot Admin Server UI 不会与 Eureka 的 UI 冲突就可以了.此处为了凸显微服务的特性,所以单独作为一个服务.
