Duplicate log entires in appinsights

[sujanakarms]

I am using OTEL Azure Monitor to export logs to application insights, the issue I am facing is duplicate log entries.
No diagnostic settings are configured on my appinsights resource. Not sure what I am missing here, please guide

Below is the snippet of code

Startup Class

    .AddOpenTelemetry()
    .UseAzureMonitor(conn =>
    {
        conn.ConnectionString = builder.Configuration["APPLICATIONINSIGHTS_CONNECTION_STRING"];
    })
    .WithTracing(builder =>
    {
        builder
            .AddAspNetCoreInstrumentation();
    });

Function code

public IActionResult Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequest req)
{
    _logger.LogInformation("Main Function Native Logging: C# HTTP trigger function processed a request.");
    return new OkObjectResult("Welcome to Azure Functions!");
}

This is not the repository for Azure Monitor. Your question belongs in this repo: https://github.com/Azure/azure-sdk-for-net/tree/main/sdk/monitor/Azure.Monitor.OpenTelemetry.AspNetCore

Since you're using Azure Functions, make sure you follow their instructions for onboarding to OpenTelemetry: https://learn.microsoft.com/azure/azure-functions/opentelemetry-howto?tabs=app-insights&pivots=programming-language-csharp

Looking at your screenshot, these are not duplicates. The timespans and customDimensions are different. This suggests to me that you possibly have multiple OpenTelemetry configurations in your process. You would need to share a full repro for anyone to investigate this.
