在actuator
下有用来监控hystrix
的端点/actuator/hystrix.stream
。
访问:
http://localhost:9202/actuator/hystrix.stream
输出:(注意监控时需要请求@HystrixCommand
配置的微服务)
ping:

接口数据查看起来不直观,可以运行hystrix dashboard
通过界面来查看。
先引入依赖
org.springframework.cloud spring-cloud-starter-netflix-hystrix-dashboard
创建启动类
@EnableHystrixDashboard @SpringBootApplication(scanBasePackages = \"com.github.mg0324\") public class StartupApplication { public static void main(String[] args) { SpringApplication.run(StartupApplication.class,args); } }
添加首页跳转,支持端口直接到hystrix
资源路径
@Controller public class HystrixIndexController { @GetMapping(\"\") public String index() { return \"forward:/hystrix\"; } }
添加配置端口
server: port: 8030 hystrix: dashboard: # 设置允许连接的IP proxy-stream-allow-list: \"192.168.3.29\"
启动服务,并访问 http://127.0.0.0:8030
在 Hystrix Dashboard 界面里的url处填写要监控的hystrix数据流地址。
如:http://192.168.3.29:9202/actuator/hystrix.stream
如果连接后的界面里什么都没有显示,则需要手动请求后,才能展现数据。可以用 ab 命令做请求压测,加大压力,让熔断器开启,图中会出现红色。
ab命令如下:ab -n 10000 -c 160 http://127.0.0.1:9201/test/test/feign/cardRand
Turbine是一个聚合Hystrix监控数据的工具,它可将所有相关/hystrix.stream端点的数据聚合到一个组合的/turbine.stream中,从而让集群的监控更加方便。
添加依赖。
org.springframework.cloud spring-cloud-starter-netflix-turbine
编写启动类。
@EnableTurbine @SpringBootApplication(scanBasePackages = \"com.github.mg0324\") public class StartupApplication { public static void main(String[] args) { SpringApplication.run(StartupApplication.class,args); } }
添加配置。
server: port: 8031 spring: application: name: card-hystrix-turbine eureka: client: service-url: defaultZone: http://192.168.3.29:8761/eureka/ instance: prefer-ip-address: true turbine: # 要监控的微服务列表,多个用,分隔 appConfig: mic-card,mic-test clusterNameExpression: \"\'default\'\"
启动服务后,得到 http://192.168.3.29:8031/turbine.stream 的聚合节点。填写到hystrix dashboard的url中做监控。
