## 1.服务监控 ##

### 1.1服务端配置 ###

pom:

<dependency>
                <groupId>de.codecentric</groupId>
                <artifactId>spring-boot-admin-starter-server</artifactId>

                <artifactId>spring-boot-admin-server-ui</artifactId>
                <version>2.0.2</version>
            </dependency>

admin-web配置

server:
      port: 8760
    spring:
      application:
        name: admin-server
      security:
        user:
          name: 'admin'
          password: 'admin'
      boot:
        admin:
          client:
              prefer-ip: true  #解决window下无法识别主机名的问题
          turbine:
              location: admin-server #管理所有的监控
              clusters: default
    turbine:
      clusterNameExpression: new String("default")
      appConfig: cloud-feign #监控的应用,逗号隔开
      instanceUrlSuffix: hystrix.stream
    eureka:
      client:
        registryFetchIntervalSeconds: 5
        service-url:
          defaultZone: http://localhost:8761/eureka/
      instance:
        leaseRenewalIntervalInSeconds: 10
        health-check-url-path: /actuator/health
        metadata-map:
          user.name: ${spring.security.user.name}
          user.password: ${spring.security.user.password}
    
    management:
      endpoints:
        web:
          exposure:
            include: "*"
      endpoint:
        health:
          show-details: ALWAYS

### 1.2客户端配置 ###

pom：

<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>

admin client配置，在eureka注册中心注册

# 如果被监控的服务没有注册到服务中心，需要增加admin的地址
    # spring.boot.admin.url=http://localhost:8760

依次启动各服务：

访问服务监控界面：[http://localhost:8760/][http_localhost_8760]

## 2.熔断器监控 ##

### 2.1配置 ###

pom依赖:

hystrix:

turbine:

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-turbine</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-turbine</artifactId>
            </dependency>

cloud-feign cloud-feign2的配置文件示例：

spring.application.name=cloud-feign
    server.port=8765
    #eureka注册地址
    eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
    #开启hystrix熔断器
    feign.hystrix.enabled=true
    management.endpoints.web.exposure.include = '*'
    #Zipkin服务器地址
    spring.zipkin.baseUrl=http://192.168.159.142:9411
    #便于测试
    spring.sleuth.sampler.percentage=1

spring.application.name=cloud-feign2
    server.port=8865
    #eureka注册地址
    eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
    #开启hystrix熔断器
    feign.hystrix.enabled=true
    #turbine配置
    turbine.app-config=cloud-feign,cloud-feign2
    #集群（cluster）（turbine聚集数据的粒度）
    turbine.aggregator.cluster-config=default
    turbine.cluster-name-expression=new String("default")
    management.endpoints.web.exposure.include = '*'
    #更改turbine连接的默认uri ,默认为/actuator/hystrix.stream
    turbine.instanceUrlSuffix = hystrix.stream
    #Zipkin服务器地址
    spring.zipkin.baseUrl=http://192.168.159.142:9411
    #便于测试
    spring.sleuth.sampler.percentage=1

### 2.2测试 ###

1.服务监控中启动各程序后，访问hystrix界面：[http://localhost:8865/hystrix][http_localhost_8865_hystrix]

以cloud-feign2作为turbine聚合客户端，在界面中输入
    http://localhost:8765/hystrix.stream
    http://localhost:8865/hystrix.stream
    http://localhost:8865/turbine.stream
    或者直接请求上述http url

cloud-feign2作为turbine聚合客户端，采集信息

## 3.zipkin调用链跟踪 ##

### 3.1配置 ###

pom依赖：

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-zipkin</artifactId>
            </dependency>

配置文件：

#Zipkin服务器地址
    spring.zipkin.baseUrl=http://192.168.159.142:9411
    #修改采集频率，便于测试
    spring.sleuth.sampler.percentage=1
    #其它配置根据需求添加

### 3.2测试 ###

zipkin使用参考：[https://zipkin.io/pages/quickstart.html][https_zipkin.io_pages_quickstart.html]

**单独启动zipkin server步骤：**

>     #下载
>     wget -O zipkin.jar 'https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=LATEST&c=exec'
>     #启动zipkin server
>     nohup java -jar zipkin.jar >>zipkin.out 2>&1 &
> 
> 访问：[http://ip][http_ip]:9411

> 1.Trace:表示对一次请求的跟踪，包括多个span,Trace就是树结构的Span集合
> 
> 2.Span:一个服务的处理
> 
> 3.traceId：标记一次请求的跟踪，相关的Spans都有相同的traceId
> 
> spanId:span的名称，一般是接口方法的名称
> 
> parentId：可选的id，当前Span的父Span id，通过parentId来保证Span之间的依赖关系，如果没有parentId，表示当前Span为根Span；

测试：

1依次启动zipkin服务，eureka各服务

2.访问：[http://localhost:8765/test?name=zyq][http_localhost_8765_test_name_zyq] [http://localhost:8865/test?name=zyq][http_localhost_8865_test_name_zyq]

3.查看zipkin界面：

> 实际项目中根据需要进行改造，如zipkin数据存储由内存改为db或者els，采集上报由http改为mq等
