如何将 c# dotnet core 3.1 微服务流绑定到涡轮服务器流

Question

我在 openshift 3 上有一个涡轮服务器运行，并使用 steeltoe 3.0.2 断路器库部署了一个 donet core 3.1 c# 微服务。我可以通过服务流 url (/hystrix/hystrix.stream) 监控 hystrix dashboard 上的微服务流。我要做的是将微服务hystrix事件流注册到涡轮服务器事件流中。有谁知道如何做到这一点？任何参考资料 link 也会有很大帮助。

更新：项目参考和设置文件配置

myproject.csproj:

<ItemGroup>
  <PackageReference Include="Steeltoe.CircuitBreaker.Hystrix.MetricsEventsCore" Version="3.0.2" />
  <PackageReference Include="Steeltoe.CircuitBreaker.HystrixCore" Version="3.0.2" />
<ItemGroup>

startup.cs：配置服务部分

services.AddMvc(options => options.EnableEndpointRouting = false);
services.AddHystrixCommand<MyCircuitBreakerCommand>("MyCircuitBreakerGroup", Configuration);
services.AddHystrixMetricsStream(Configuration);

startup.cs -> 配置部分

app.UseHystrixRequestContext();
app.UseHystrixMetricsStream();
app.UseMvc();

我也没有修改 program.cs 或任何 .json 设置文件。

最近尝试访问这些微服务资源：/hystrix/config.stream、/hystrix/request.stream 和 /hystrix/utilization.stream，但收到此内部服务器错误：

Answer 1

此错误消息告诉我们 HystrixConfigurationStream 尚未注册到服务容器。可以在 startup.cs:

中使用此代码添加

services.AddHystrixConfigStream(Configuration);

但我认为更好的选择是将 AddHystrixMetricsStream 复数化为 AddHystrixMonitoringStreams，这也注册了 a couple other things。

我个人并没有花很多时间在这段代码上，所以我不知道到底发生了什么，但我已经 filed an issue 了文档，如果有错误，我们应该能够跟进修复。
