Multiple independent HTTP requests are aggregated into a single trace for unknown reasons

[svirchenko]

Hi there,

I have ASP NET Core web app which is configured with OpenTelemetry .NET library for exporting traces to Azure Monitor. Unfortunately, I faced an issue that multiple independent HTTP requests are grouped into a single trace for unknown reasons. This issue is not for all requests.

I have the following OpenTelemetry configuration:

internal static IServiceCollection RegisterOpenTelemetry(this IServiceCollection services,
        IConfiguration configuration)
{
    services.AddOpenTelemetry()
        .WithTracing(builder => builder
            .SetSampler(new AlwaysOnSampler())
            .AddSource(nameof(DirectExchangePublisher))
            .AddSource("Azure.*")
            .AddHttpClientInstrumentation()
            .AddAspNetCoreInstrumentation()
            .AddAzureMonitorTraceExporter(options =>
            {
                if (string.IsNullOrEmpty(configuration["APPLICATIONINSIGHTS_CONNECTION_STRING"]))
                {
                    Log.Logger.Warning("OpenTelemetry is not exported because \"APPLICATIONINSIGHTS_CONNECTION_STRING\" is missing");
                }
               
                options.ConnectionString = configuration["APPLICATIONINSIGHTS_CONNECTION_STRING"];
            }));
    return services;
}

I would be grateful for any advice or help.

Many thanks,
Serhii
