OpenTelemetry 跟踪未发送到 Azure

Question

我使用 OpenTelemetry 来检测 ASP.NET Core 项目并收集日志和跟踪。收集后，两者都应发送到 Azure Application Insights 资源以进行存储和查询。问题是，虽然日志和跟踪都成功捕获并显示在控制台上，但只有日志被发送到 Application Insights。无论我对配置进行什么更改，我似乎都无法在 Azure 中显示痕迹。我很想在跟踪表中看到哪怕是一条带有关联 ID 的跟踪。有谁知道为什么跟踪没有发送到 Azure？

请参阅下面的 OpenTelemetry 配置。

private void ConfigureOpenTelemetry(IServiceCollection services)
{
    var applicationInsightsConnectionString = "valid-connection-string";
    var serviceName = "backend-service-name"
    services.AddOpenTelemetry()
        .ConfigureResource(resource => resource.AddService(serviceName))
        .UseAzureMonitor(options =>
        {
            options.ConnectionString = applicationInsightsConnectionString;
        })
        .WithTracing(builder =>
        {
            builder.AddSource("ActivitySourceName");
            builder.AddAspNetCoreInstrumentation();
            builder.AddConsoleExporter();
            builder.AddAzureMonitorTraceExporter(o => o.ConnectionString = applicationInsightsConnectionString);
        });

    services.AddLogging(logging =>
    {
        logging.AddOpenTelemetry(options =>
        {
            options.SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(serviceName));
            options.AddConsoleExporter();
            options.AddAzureMonitorLogExporter(o => o.ConnectionString = applicationInsightsConnectionString);
        });
    });
}

我尝试了无数种配置 OpenTelemetry 的变体，并进行了三次检查，看看我的配置是否与文档和示例应用程序中的相同

我尝试过使用 .NET Core 8，并且能够使用您的代码和以下配置在 Application Insights 中查看跟踪、依赖项和请求。

我的

appsettings.json

文件：

{
  "Logging": {
    "ApplicationInsights": {
      "LogLevel": {
        "Default": "Debug",
        "Microsoft": "Error"
      }
    },
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  }
}

本地控制台中显示的日志在 Application Insights 中显示为不同的参数。

本地：

info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:5161
LogRecord.Timestamp:               2025-01-10T10:28:30.0781350Z
LogRecord.CategoryName:            Microsoft.Hosting.Lifetime
LogRecord.Severity:                Info
LogRecord.SeverityText:            Information
LogRecord.FormattedMessage:        Now listening on: http://localhost:5161
LogRecord.Body:                    Now listening on: {address}
LogRecord.Attributes (Key:Value):
    address: http://localhost:5161
    OriginalFormat (a.k.a Body): Now listening on: {address}
LogRecord.EventId:                 14
LogRecord.EventName:               ListeningOnAddress

Resource associated with LogRecord:
service.name: New Service Name
service.instance.id: b7bffadb-3981-4b27-bb69-e95644b8321a
telemetry.sdk.name: opentelemetry
telemetry.sdk.language: dotnet
telemetry.sdk.version: 1.10.0

Transaction Search

：

• Application Insights 中显示的日志与 Trace 相同。

服务实例 ID 显示为

RoleInstance

。

• 我的

  .csproj.cs
