springboot admin turbine 配置详解

  由于 hystrix 对流量的监控状态的监控是单应用的。有的时候我们需要全面查看整个系统的监控状态，那么我们可能需要引入turbine 的监控检查。在spring boot admin 已经有spring-boot-admin-server-ui-turbine 这个插件

   turbine 是一个hystrix 的集合。里面展示所有的hystrix的效果。我们这里用的spring cloud的版本是

<spring-boot.version>1.5.3.RELEASE</spring-boot.version>
<spring-cloud.version>Dalston.SR1</spring-cloud.version>
<spring-boot-admin.version>1.5.0</spring-boot-admin.version>

1、配置turbine 的包依赖

<dependencies>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-server</artifactId>
        <version>${spring-boot-admin.version}</version>
    </dependency>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-server-ui</artifactId>
        <version>${spring-boot-admin.version}</version>
    </dependency>
    <dependency>
        <groupId>de.codecentric</groupId>
        <artifactId>spring-boot-admin-server-ui-turbine</artifactId>
        <version>${spring-boot-admin.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-turbine</artifactId>
    </dependency>
</dependencies>

2、配置启动类

//www.1b23.com
@SpringBootApplication
@EnableAdminServer
@EnableDiscoveryClient
@EnableTurbine
open class YkbBootAdminServerApplication {

    companion object {
        @JvmStatic fun main(args: Array<String>) {
            SpringApplication.run(YkbBootAdminServerApplication::class.java, *args)
        }
    }
}

启动类配置了@EnableTurbine

3、配置启动项：（application.properties）

spring.boot.admin.routes.endpoints= env,metrics,trace,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream,turbine.stream
spring.boot.admin.turbine.location=TGS-SPRING-BOOT-ADMIN

management.security.enabled=false
security.basic.enabled=false

turbine.clusterNameExpression=new String("default")
turbine.appConfig=YKB-ACCOUNT-MOBILE
turbine.combineHostPort=true

其中endpoints 配置hystrix.stream,turbine.stream

配置了spring.boot.admin.turbine.location=TGS-SPRING-BOOT-ADMIN

代表是由TGS-SRPING-BOOT-ADMIN实例来管理所有的监控

springcloud 项目案例 www.1b23.com

最后

turbine.appConfig=YKB-ACCOUNT-MOBILE 
代表你可以监控的应用有哪些，可以用逗号隔开

4、配置hystrix  

 ykb-account-mobile 配置熔断机制 这里采用 @SpringCloudApplication里面包含了熔断机制

@SpringCloudApplication
@EnableZuulProxy
@EnableFeignClients
open class AccountMobileApplication  {

     //www.1b23.com
    @LoadBalanced
    @Bean
    open fun restTemplate(): RestTemplate {
        return RestTemplate()
    }

    companion object {

        @JvmStatic fun main(args: Array<String>) {
            SpringApplication.run(AccountMobileApplication::class.java, *args)
        }
    }
}

需要引入的jar包为

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zuul</artifactId>
</dependency>

其中application的配置为

server.port=7180
management.port=7181

eureka.instance.prefer-ip-address = true
eureka.instance.lease-renewal-interval-in-seconds=10
eureka.instance.lease-expiration-duration-in-seconds=30
eureka.client.service-url.defaultZone= http://eureka.ejuda.net:8761/eureka/
eureka.client.fetch-registry=true
eureka.instance.metadata-map.management.port= ${management.port}

其中eureka.instance.metadata-map.management.port=${management.port}

是必须的。因为管理端口跟服务端口不一样
