service.name is defined as unknown_service

[jmurrayrs]

I'm configuring an Action in .NET 8 setting service name:

Action<ResourceBuilder> configureResource = r => r.AddService(
            serviceName: "xpto",
            serviceVersion: settings.ServiceVersion,
            serviceInstanceId: Environment.MachineName);

and I'm registering here

serviceCollection.
            .AddOpenTelemetry()
            .ConfigureResource(configureResource)
             .WithTracing(builder =>
                        {
                            builder                           
                                .AddNpgsql()
                                .AddEntityFrameworkCoreInstrumentation(options =>
                                {
                                    options.EnrichWithIDbCommand = (activity, command) =>
                                    {
                                        //var stateDisplayName = $"{command.CommandType} main";
                                        var stateDisplayName = command.GetType().FullName;
                                        activity.DisplayName = stateDisplayName!;
                                        activity.SetTag("db.name", stateDisplayName);
                                    };
                                })
                                .AddAspNetCoreInstrumentation(opts =>
                                {
                                    opts.EnrichWithHttpRequest = (a, r) => a?.AddTag("env", environmentName);
                                    opts.RecordException = true;
            
                                })
                                .AddOtlpExporter(config =>
                                {
                                    config.Endpoint = new Uri(settings.Exporter.Endpoint);
                                })
                                .AddConsoleExporter();
            
                        })
                        .WithMetrics(builder =>
                        {
                            builder
                                .AddMeter(metrics.Name)
                                .AddRuntimeInstrumentation()
                                .AddAspNetCoreInstrumentation()
                                .AddOtlpExporter(config =>
                                {
                                    config.Endpoint = new Uri(settings.Exporter.Endpoint ?? string.Empty);
                                })
                                .AddConsoleExporter();
                        });

But, when I see the logs, the service.name is unknown_service

  "resources": {
    "service.name": "unknown_service:dotnet",
    "telemetry.sdk.language": "dotnet",
    "telemetry.sdk.name": "serilog",
    "telemetry.sdk.version": "1.2.0"
  },

How Can I set the service name correctly ?

Thanks !

@jmurrayrs I think in your code the Action was applied to metrics and traces, but not logs.

logging.SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(
