将我的应用程序(堆栈弹簧靴,骆驼,hystrix)从弹簧靴1.5迁移到弹簧靴2之后。我无法在/ actuator / prometheus中显示hystrix指标。

正如许多解决方案和教程所建议的那样,我确保我具有以下依赖性

<dependency>
   <groupId>io.micrometer</groupId>
   <artifactId>micrometer-registry-prometheus</artifactId>
   <version>${micrometer-version}</version>
</dependency>
<dependency>
   <groupId>io.micrometer</groupId>
   <artifactId>micrometer-core</artifactId>
   <version>${micrometer-version}</version>
</dependency>


并添加了以下配置类,我已经确定它已被实例化,因为我已经在spring boot自动配置日志中进行了检查:

import io.micrometer.core.instrument.binder.hystrix.HystrixMetricsBinder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class HystrixMetricsConfig {

   @Bean
   HystrixMetricsBinder registerHystrixMetricsBinder() {
      return new HystrixMetricsBinder();
   }
}


为了避免假设此类教程/答案在定义上是正确的,我从头开始设置了一个简单的spring boot项目,其中包含一个简单的控制器,hystrix和上述依赖性,并且指标确实出现在/ actuator / prometheus中,而无需执行其他步骤。

与简单项目相比,我的应用程序具有更多的依赖关系,因此我认为可能有其他事情要覆盖/禁用指标绑定。

除了被告知实际问题是什么之外,我还在努力了解如何解决此类问题。是否可以激活任何千分尺/弹簧启动日志(自动配置报告除外)以了解发生了什么?

最佳答案

在遵循整个自定义hystrix度量标准绑定过程之后,我最终发现,至少在原则上,所有内容都正确地绑定了。

然后,我尝试在首次执行hystrix命令时触发一个断点,以检查注册表和发布者的情况。在方法中放置断点

HystrixMetricsPublisherThreadPool getPublisherForThreadPool(HystrixThreadPoolKey threadPoolKey, HystrixThreadPoolMetrics metrics, HystrixThreadPoolProperties properties)


HystrixMetricsPublisherFactory类的基础上,我发现HystrixPlugins实例与设置发布者的时间有所不同。
检查完应用程序的所有代码后,我发现,要设置自定义事件通知程序,实例将被重置。

@EventListener(ApplicationReadyEvent.class)
    public void doAfterStartup() {
        Hystrix.reset();
        registerCustomHystrixEventNotifier(circuitBreakerHystrixEventNotifier);
        logger.info("hello world, application started up");
    }


然后,我修改了该方法以注册事件通知程序,而无需重置之前配置的自动配置,并且hystrix指标现在显示在prometheus端点中。

关于java - 将应用程序迁移到Spring Boot 2之后,无法将hystrix指标公开给/actuator/prometheus,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/57844565/
