// 1. Insall dependencies
//Gradle:
dependencies {
    implementation 'io.opentelemetry:opentelemetry-exporter-otlp:1.39.0'
}

// 2. Configure exporter
env OTEL_EXPORTER_OTLP_ENDPOINT=http://example:4317 java -jar ./build/libs/java-simple.jar

// 3. Integrate with your application

Install and setup OpenTelemetry in your app.

// Getting Started Doc: https://opentelemetry.io/docs/languages/net/getting-started/
// Use gRPC OTEL Exporter: https://opentelemetry.io/docs/languages/net/exporters/#otlp-dependencies

// 1. Install OpenTelemetry NuGet Packages

dotnet add package OpenTelemetry.Exporter.OpenTelemetryProtocol
dotnet add package OpenTelemetry.Extensions.Hosting
dotnet add package OpenTelemetry.Instrumentation.Http
dotnet add package OpenTelemetry.Instrumentation.Runtime

// 2. Optional Hosting Extensions
dotnet add package Microsoft.Extensions.Hosting

// 3. Add configuration endpoint in environment variables

"OTEL_EXPORTER_OTLP_ENDPOINT": "http://localhost:4317"

// 4. Configure open telemetry in your app

using ConsoleApp;
using OpenTelemetry;
using OpenTelemetry.Metrics;
using OpenTelemetry.Resources;
using OpenTelemetry.Trace;

var builder = Host.CreateApplicationBuilder(args);

ConfigureOpenTelemetry(builder);

var host = builder.Build();

        })
        .WithTracing(tracing =>
        {
            tracing.AddHttpClientInstrumentation();
        });

    // Use the OTLP exporter if the endpoint is configured.
    var useOtlpExporter = !string.IsNullOrWhiteSpace(builder.Configuration["OTEL_EXPORTER_OTLP_ENDPOINT"]);
    if (useOtlpExporter)
    {
