Description

OTLP exporter should have its endpoint explicitly configured rather than relying on the default localhost:4317, which often does not exist in production.

​
Bad Code

builder.Services.AddOpenTelemetry()
    .WithTracing(t => t.AddOtlpExporter()); // default endpoint

​
Good Code

builder.Services.AddOpenTelemetry()
    .WithTracing(t => t.AddOtlpExporter(o =>
        o.Endpoint = new Uri("https://collector.example.com:4317")));
