Hystrix-dashboard 是一款针对 Hystrix 进行实时监控的工具,通过 Hystrix Dashboard 我们可以在直观地看到各 Hystrix Command 的请求响应时间, 请求成功率等数据。
项目中添加依赖
<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-hystrix-dashboard</artifactId>
</dependency>
启动类中添加注解:
@EnableHystrix:表示当前程序开启数据监控
@EnableHystrixDashboard:表示当前程序开启数据监控的可视化视图程序
@EnableHystrix
@EnableHystrixDashboard
public class ConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerApplication.class, args);
}
}
查看当前服务的监控信息---json字串格式的数据
http://服务ip:端口/hystrix.stream
使用视图模式查看
http://服务ip:端口/hystrix
监控中心界面介绍
使用 Turbine 在多个服务与集群情况下收集数据监控
Turbine 是聚合服务器发送事件流数据的一个工具,hystrix 的监控中,只能监控单个节点,实际生产中都为集群,因此可以通过 turbine 来监控集群服务。
添加依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-turbine</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-netflix-turbine</artifactId>
</dependency>
application配置文件中配置Turbine
#---------------------------------------turbine--------------------------
#配置 Eureka 中的 serviceId 列表,表明监控哪些服务
turbine.appConfig=eureka-consumer-ribbon-threadpool,springcloud-eureka-consumer-feign-fallback
#指定聚合哪些集群,多个使用","分割,默认为 default。可使用http://.../turbine.stream?cluster={clusterConfig 之一}访问
turbine.aggregator.clusterConfig= default
# 1. clusterNameExpression 指定集群名称,默认表达式 appName;此时:turbine.aggregator.clusterConfig 需要配置想要监控的应用名称;
# 2. 当 clusterNameExpression: default 时,turbine.aggregator.clusterConfig 可以不写,因为默认就是 default;
# 3. 当 clusterNameExpression: metadata['cluster']时,假设想要监控的应用配置了 eureka.instance.metadata-map.cluster: ABC,
# 则需要配置,同时 turbine.aggregator.clusterConfig: ABC
turbine.clusterNameExpression="default"
启动类中添加@EnableTurbine注解,启用Turbine服务
@SpringBootApplication
@EnableTurbine
public class HystrixTurbineApplication {
public static void main(String[] args) {
SpringApplication.run(HystrixTurbineApplication.class, args);
}
}
在被聚合的项目的 pom 文件添加 dashboard 坐标
<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-hystrix-dashboard</artifactId>
</dependency>
在被聚合的项目的启动类上添加@EnableHystrixDashboard注解
@EnableFeignClients
@EnableDiscoveryClient
@SpringBootApplication
@EnableHystrixDashboard
@EnableCircuitBreaker
public class ConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerApplication.class, args);
}
}
然后通过Hystrix视图页面输入监控地址:http:// turbine服务IP : 端口 / turbine.stream即可看到监控数据视图
采用 RabbitMQ,收集监控数据
在需要监控的Consumer 服务服务中添加依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-netflix-hystrix-stream</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>
然后再application配置文件中配置RabbitMQ连接信息
spring.rabbitmq.host=192.168.1.19
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=1111
spring.rabbitmq.virtualHost=/
然后再启动类中添加@EnableHystrix和@EnableHystrixDashboa注解
@EnableCircuitBreaker
@EnableEurekaClient
@SpringBootApplication
@EnableHystrix
@EnableHystrixDashboard
public class ConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerApplication.class, args);
}
}
创建 Turbine 项目添加依赖
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-turbine-stream</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-stream-rabbit</artifactId>
</dependency>
然后同样配置RabbitMQ连接信息
spring.rabbitmq.host=192.168.1.19
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=1111
spring.rabbitmq.virtualHost=/
Turbine 的启动类中添加@EnableTurbineStream注解
@SpringBootApplication
@EnableTurbineStream
public class HystrixTurbineApplication {
public static void main(String[] args) {
SpringApplication.run(HystrixTurbineApplication.class, args);
}
}
然后通过Hystrix视图页面输入监控地址:http:// turbine服务IP : 端口 / turbine.stream即可看到监控数据视图
