SpringCloud学习之三：Turbine聚合监控 Turbine聚合监控 Spring Cloud版本：Hoxton.SR5 1. 简介上一章已经搭建了简单的服务提供者和服务消费者，并且服务消费者集成了断路器Hystrix，并且可通过actuator暴露的/actuator/hystrix.stream端点进行监控。但显示数据为纯文本形式，所以可进行如下优化。使用Hystrix Dashboard进行图形化显示可进行图形化显示，观察方便多个微服务仅能一个一个进行查看同一个微服务有多个实例进行负载均衡时，无法进行汇总查看使用Turbi 阅读详情

简单上手，直接照搬，就可搭建微服务(Hoxton.SR8) 2020.8.28发布，SpringCloud搭建的文章正在整理，干货不要错过哦

摘要

Hystrix Dashboard 是Spring Cloud中查看Hystrix实例执行情况的一种仪表盘组件，支持查看单个实例和查看集群实例。Hystrix提供了Hystrix Dashboard来实时监控HystrixCommand方法的执行情况。 Hystrix Dashboard可以有效地反映出每个Hystrix实例的运行情况，帮助我们快速发现系统中的问题，从而采取对应措施。

1. 创建一个hystrix-dashboard 服务

1.1 pom.xml新增 dashboard 依赖

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <!-- 包含了web -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
        </dependency>
</dependencies>

1.2 启动类新增 @EnableCircuitBreaker 和 @EnableDiscoveryClient

package com.zqh.www;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.core.env.Environment;

/**
 * 开启服务发现客户端
 *
 * @EnableEurekaClient只适用于Eureka作为注册中心，@EnableDiscoveryClient 可以是其他注册中心。
 */
@EnableDiscoveryClient
/**
 * 开启监控
 */
@EnableHystrixDashboard
@SpringBootApplication
public class HystrixDashboardApplication {

    private final static Logger logger = LoggerFactory.getLogger(HystrixDashboardApplication.class);

    public static void main(String[] args) {
        Environment env = SpringApplication.run(HystrixDashboardApplication.class, args).getEnvironment();
        logger.info(
                "\n----------------------------------------------------------\n\t"
                        + "Application '{}' is running! Access URLs:\n\t"
                        + "Local: \t\thttp://localhost:{}{}"
                        + "\n----------------------------------------------------------",
                env.getProperty("spring.application.name"), env.getProperty("server.port"),
                env.getProperty("server.servlet.context-path") != null ? env.getProperty("server.servlet.context-path") : "");
    }
}

1.3 yml配置

server:
  port: 8089
spring:
  application:
    name: hystrix-dashboard
eureka:
  client:
    service-url:
      #注册地址
      defaultZone: http://root:root@localhost:8081/eureka/
  #显示服务器IP加端口
  instance:
    hostname: localhost
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}

# is not in the allowed list of proxy host names.  If it should be allowed add it to hystrix.dashboard.proxyStreamAllowList.
hystrix:
  dashboard:
    proxy-stream-allow-list: "localhost"

1.4 启动服务

访问：点击访问Dashboard服务：http://localhost:8089/hystrix

注意：因为我们使用的不是https.所以我们填写的时候是填http

1.5 在hystrix-service服务中的HystrixServiceApplication添加监听

注意：是在hystrix-service服务

package com.zqh.www;

import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.cloud.client.SpringCloudApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.context.annotation.Bean;
import org.springframework.core.env.Environment;

/**
 * 开启断路器功能
 */
@EnableCircuitBreaker
/**
 * 开启服务发现客户端
 * @EnableEurekaClient只适用于Eureka作为注册中心，@EnableDiscoveryClient 可以是其他注册中心。
 */
@EnableDiscoveryClient
@SpringBootApplication
/**
 * 可以取代上面三个
 */
@SpringCloudApplication
public class HystrixServiceApplication {

    private final static Logger logger = LoggerFactory.getLogger(HystrixServiceApplication.class);

    public static void main(String[] args) {
        Environment env = SpringApplication.run(HystrixServiceApplication.class, args).getEnvironment();
        logger.info(
                "\n----------------------------------------------------------\n\t"
                        + "Application '{}' is running! Access URLs:\n\t"
                        + "Local: \t\thttp://localhost:{}{}"
                        + "\n----------------------------------------------------------",
                env.getProperty("spring.application.name"), env.getProperty("server.port"),
                env.getProperty("server.servlet.context-path") != null ? env.getProperty("server.servlet.context-path") : "");
    }

    /**
     * 解决问题：Dashboard显示Unable to connect to Command Metric Stream。
     *
     * @return
     */
    @Bean
    public ServletRegistrationBean getServlet() {
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }
}

1.6 填写Hystrix Dashboard页面内容

注意：
第一行参数是填写需要监听的服务链接

第二行参数是填写服务名，可以随便填，用来只是一个名字，建议于需要监听的服务名称相同

2.Hystrix Dashboard 图表解析

3.Hystrix 集群实例监控

如果服务集群了怎么办呢？Turbine可以聚合hystrix-service服务的监控信息，然后我们的hystrix-dashboard服务就可以从Turbine获取聚合好的监控信息。

3.1 创建一个turbine-service模块

3.2 pom.xml新增 turbine依赖

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
        </dependency>
    </dependencies>

3.3 启动类新增 @EnableTurbine和 @EnableDiscoveryClient

package com.zqh.www;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.turbine.EnableTurbine;
import org.springframework.core.env.Environment;

/**
 * 开启服务发现客户端
 *
 * @EnableEurekaClient只适用于Eureka作为注册中心，@EnableDiscoveryClient 可以是其他注册中心。
 */
@EnableDiscoveryClient
/**
 * 开启监控
 */
@EnableTurbine
@SpringBootApplication
public class TurbineHystrixApplication {

    private final static Logger logger = LoggerFactory.getLogger(TurbineHystrixApplication.class);

    public static void main(String[] args) {
        Environment env = SpringApplication.run(TurbineHystrixApplication.class, args).getEnvironment();
        logger.info(
                "\n----------------------------------------------------------\n\t"
                        + "Application '{}' is running! Access URLs:\n\t"
                        + "Local: \t\thttp://localhost:{}{}"
                        + "\n----------------------------------------------------------",
                env.getProperty("spring.application.name"), env.getProperty("server.port"),
                env.getProperty("server.servlet.context-path") != null ? env.getProperty("server.servlet.context-path") : "");
    }
}

3.4 yml配置

server:
  port: 8090
spring:
  application:
    name: turbine-service
eureka:
  client:
    service-url:
      #注册地址
      defaultZone: http://root:root@localhost:8081/eureka/
  #显示服务器IP加端口
  instance:
    hostname: localhost
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}

turbine:
  # 指定需要收集信息的服务名称
  app-config: hystrix-service
  # 指定服务所属集群
  cluster-name-expression: new String('default')
  # 以主机名和端口号区分服务
  combine-host-port: true
