Hystrix的Dashboard仪表盘与turbine集群监控

1. Hystrix服务监控Dashboard仪表盘

Hystrix提供了准实时的服务调用监控项目Dashboard，能够实时记录通过Hystrix发起的请求执行情况，可以通过图表的形式展现给用户看。

1.1) 新建项目microservice-student-consumer-hystrix-dashboard-90

new -> Maven Module
    -> create a simple project
Module Name: microservice-student-consumer-hystrix-dashboard-90
Parent Project:microservice
Working set:SpringCloud
    -> Artifact
Group Id:com.andrew.springcloud
Artifact Id: microservice-student-consumer-hystrix-dashboard-90
Version:0.0.1-SNAPSHOT
Packaging:jar

1.2) 项目microservice-student-consumer-hystrix-dashboard-90增加pom.xml依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.andrew.springcloud</groupId>
        <artifactId>microservice</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <artifactId>microservice-student-consumer-hystrix-dashboard-90</artifactId>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>
</project>

1.3) 项目microservice-student-consumer-hystrix-dashboard-90配置application.yml

server:
  port: 90
  context-path: /

1.4) 新建启动类StudentConsumerDashBoardApplication_90.java

package com.andrew;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class })
@EnableHystrixDashboard
public class StudentConsumerDashBoardApplication_90 {
    public static void main(String[] args) {
        SpringApplication.run(StudentConsumerDashBoardApplication_90.class, args);
    }
}

启动microservice-student-consumer-hystrix-dashboard-90
http://localhost:90/hystrix

microservice-student-provider-hystrix-1004中com.andrew.controller. StudentProviderController.java修改Thread.sleep(1000);

启动microservice-eureka-server-2001
启动microservice-eureka-server-2002
启动microservice-eureka-server-2003
启动microservice-student-provider-hystrix-1004
http://localhost:1004/student/getInfo
{"code":200,"info":"业务数据xxxxx"}

监控地址
http://localhost:1004/hystrix.stream

在http://localhost:90/hystrix中输入http://localhost:1004/hystrix.stream
通过访问http://localhost:1004/student/getInfo
可以显示

2. Hystrix集群监控turbine

新建集群
    microservice-student-provider-hystrix-1004(已有)
    microservice-student-provider-hystrix-1005

2.1) 新建项目microservice-student-provider-hystrix-1005

代码与microservice-student-provider-hystrix-1004相同

2.2) 项目microservice-student-provider-hystrix-1005修改application.yml配置

server:
  port: 1005
  instance-id: microservice-student-hystrix:1005 #客户端实例名称

2.3) 修改启动类StudentProviderHystrixApplication_1005.java

package com.andrew;

import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
@EnableCircuitBreaker
public class StudentProviderHystrixApplication_1005 {
    public static void main(String[] args) {
        SpringApplication.run(StudentProviderHystrixApplication_1005.class, args);
    }
}

2.4) 新建项目microservice-student-consumer-hystrix-turbine-91

turbine: 
  app-config: microservice-student   # 指定要监控的应用名称 
  clusterNameExpression: "'default'" #表示集群的名字为default
spring: 
  application: 
    name: turbine

@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class })
@EnableTurbine
public class StudentConsumerTurbineApplication_91 {
    public static void main(String[] args) {
        SpringApplication.run(StudentConsumerTurbineApplication_91.class, args);
    }
}

启动microservice-eureka-server-2001
启动microservice-eureka-server-2002
启动microservice-eureka-server-2003
启动microservice-student-provider-hystrix-1004
启动microservice-student-provider-hystrix-1005
启动microservice-student-consumer-80
启动microservice-student-consumer-hystrix-dashboard-90
启动microservice-student-consumer-hystrix-turbine-91

http://localhost:91/turbine.stream

进入http://localhost:90/hystrix
输入http://localhost:91/turbine.stream点击确认
通过调用http://localhost/student/getInfo来请求

正常显示Hystrix Stream曲线图
