Can't see the logs, traces

[felipe-lettrlabs]

I am using Docker Compose to start the container for tests, and a .NET app to send the OpenTelemetry (OTel) data to the collector. However, when I try to see the data in Grafana, it does not appear

I got some logs in Docker

logger=authn.service t=2025-02-27T20:45:01.98711316Z level=warn msg="Failed to authenticate request" client=auth.client.session error="user token not found"

And this is my docker compose

services: grafana: container_name: grafana image: grafana/otel-lgtm:latest ports: - "3111:3000" - "4317:4317" - "4318:4318" environment: ENABLE_LOGS_ALL: "true" OTEL_METRIC_EXPORT_INTERVAL: 1000 healthcheck: test: test -e /tmp/ready interval: 5s timeout: 2s retries: 20

And my .net code

`Action configureResource = r => r.AddService(
serviceName: appBuilder.Configuration.GetValue("ServiceName", defaultValue: "otel-test")!,
serviceVersion: typeof(Program).Assembly.GetName().Version?.ToString() ?? "unknown",
serviceInstanceId: Environment.MachineName);

//var serviceName = "AppTest";
var otelUrl = "http://localhost:4317";

appBuilder.Logging.AddOpenTelemetry(options =>
{
var resourceBuilder = ResourceBuilder.CreateDefault();
configureResource(resourceBuilder);
options.SetResourceBuilder(resourceBuilder);

options
    .AddOtlpExporter(x =>
    {
        x.Endpoint = new Uri(otelUrl);
        x.Protocol = OtlpExportProtocol.Grpc;
    })
    .AddConsoleExporter();

});

appBuilder.Services.AddOpenTelemetry()
.ConfigureResource(configureResource)
.WithTracing(tracing => tracing
.AddAspNetCoreInstrumentation()
.AddHttpClientInstrumentation()
.AddConsoleExporter()
.AddOtlpExporter(x =>
{
x.Endpoint = new Uri(otelUrl);
x.Protocol = OtlpExportProtocol.Grpc;
})
).WithMetrics(metrics => metrics
//.AddRuntimeInstrumentation()
.AddProcessInstrumentation()
.AddHttpClientInstrumentation()
//.AddAWSInstrumentation()
.AddMeter()
//.AddPrometheusExporter()
.AddAspNetCoreInstrumentation()
.AddConsoleExporter()
.AddOtlpExporter(x =>
{
x.Endpoint = new Uri(otelUrl);
x.Protocol = OtlpExportProtocol.Grpc;
})
);`
