spring boot 2.x spring cloud Greenwich.SR1 hystrix Dashboard监控搭建使用

1、项目搭建

1.1、新建项目`badger-spring-cloud-hystrix-dashboard`，pom文件如下，引入hystrix和 hystrix-dashboard相关
1.2、新建主启动类`HystrixDashboardApplication`，并且加上`@EnableHystrixDashboard`注解
1.3、ymal配置文件，就只是配置了启动端口8764
1.4、启动项目
1.5、被监控的应用，改造上一篇搭建的`badger-spring-cloud-openfeign-hystrix`应用；新增`actuator`监控的jar包

2、项目启动，演示测试

本次例子是基于上一次构建的 badger-spring-cloud-openfeign-hystrix项目的基础上，使用的；

1、项目搭建

1.1、新建项目`badger-spring-cloud-hystrix-dashboard`，pom文件如下，引入hystrix和 hystrix-dashboard相关

            </plugin>
        </plugins>
    </build>

</project>

1.2、新建主启动类`HystrixDashboardApplication`，并且加上`@EnableHystrixDashboard`注解

/**
 * @EnableHystrixDashboard  开启断路器仪表盘 hystrix dashboard 
   http://localhost:8764/hystrix
 * @author liqi
 *
 */
@SpringBootApplication
@EnableHystrixDashboard
public class HystrixDashboardApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(HystrixDashboardApplication.class, args);
    }
}

1.3、ymal配置文件，就只是配置了启动端口8764

server:
  port: 8764

1.4、启动项目

http://localhost:8764/hystrix

看到这个豪猪的页面，项目就搭建完成了，下面说明下页面上要表达的意思

Hystrix Dashboard共支持三种不同的监控方式

default cluster（查看默认的集群）：http://turbine-hostname:port/turbine.stream
custom cluster（查看指定的集群节点）:http://turbine-hostname:port/turbine.stream?cluster=[clusterName]
Single Hystrix App（单个应用）：http://hystrix-app:port/actuator/hystrix.stream

三个输入框

第一个：输入需要监控应用的地址

Delay：刷新的频率默认是2秒（2000ms）

Title：应用的标题

1.5、被监控的应用，改造上一篇搭建的`badger-spring-cloud-openfeign-hystrix`应用；新增`actuator`监控的jar包

 <!-- actuator监控信息 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

yaml配置文件中，新增

management:
  endpoints:
    web:
      exposure:
        include: '*'

新增这个配置，是开放所有的actuator监控路径，springboot2.x之后，只暴露了info和health两个节点，并且actuator监控的路由，加了/actuator路由

部分actuator监控的配置类如下org.springframework.boot.actuate.autoconfigure.endpoint.web.WebEndpointProperties

@ConfigurationProperties(prefix = "management.endpoints.web")
public class WebEndpointProperties {

	private final Exposure exposure = new Exposure();

	/**
	 * Base path for Web endpoints. Relative to server.servlet.context-path or
	 * management.server.servlet.context-path if management.server.port is configured.
	 */
	private String basePath = "/actuator";

	/**
	 * Mapping between endpoint IDs and the path that should expose them.
	 */
	private final Map<String, String> pathMapping = new LinkedHashMap<>();

	public Exposure getExposure() {
		return this.exposure;
	}

yaml全部配置如下

server:
  port: 7300
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
  instance:
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true
spring:
  application:
    name: badger-spring-cloud-openfeign-hystrix
feign:
  hystrix:
    enabled: true
management:
  endpoints:
    web:
      exposure:
        include: '*'
