instrumentation.{js|ts} script debugging

[chicoxyzzy]

Is there any way to debug the instrumentation script?

I'm trying to add logging in this way:

import { registerOTel, OTLPHttpProtoTraceExporter } from "@vercel/otel";
import { OTLPLogExporter } from '@opentelemetry/exporter-logs-otlp-proto';
import { SimpleLogRecordProcessor, LoggerProvider } from '@opentelemetry/sdk-logs';

export function register() {
  const loggerProvider = new LoggerProvider();

  const logExporter = new OTLPLogExporter({
    url: process.env.OTEL_EXPORTER_OTLP_ENDPOINT,
  });
  const logRecordProcessor = new SimpleLogRecordProcessor(logExporter);
  loggerProvider.addLogRecordProcessor(logRecordProcessor);

  registerOTel({
    serviceName: "service-name",
    traceExporter: new OTLPHttpProtoTraceExporter({
      url: process.env.OTEL_EXPORTER_OTLP_ENDPOINT,
    }),
    logRecordProcessor,
  });
}

The application deployment works, but when I open a preview, the application looks broken and for some reason have CSS for some reason. When I comment out logging, the app works again. There's no logs for instrumentation.ts anywhere in the Vercel dashboard or in terminal.

@chicoxyzzy do you have an example of how you're calling the log write?

I'm trying to setup logging and tracing correlation.

I'm trying pino and setting up the @opentelemetry/instrumentation-pino instrumentations but thats throwing a Module not found: Can't resolve 'stream'

My goal is to write a shared Logging class that I can call in the business logic.

Is your stuff working on vercel edge?
