Question: Vercel OpenTelemetry Collector for Datadog

Help

@ethanshea - I saw the code you linked and tried to use a logRecordProcessor to customize the logs before it is forwarded to Datadog. However this code here is not doing anything, the onEmit never gets called:

export function register() {
  registerOTel({
    serviceName: SERVICE_NAME,
    attributes: {
      'service.name': SERVICE_NAME,
      'service.version': process.env.VERCEL_DEPLOYMENT_ID || 'unavailable',
      env: process.env.VERCEL_ENV || 'unavailable',
      environment: process.env.VERCEL_ENV || 'unavailable',
      'deployment.environment': process.env.VERCEL_ENV || 'unavailable'
    },
    spanProcessors: [new DatadogSpanProcessor(), 'auto'],
    logRecordProcessor: new DatadogLogProcessor()
  });
}

class DatadogLogProcessor implements LogRecordProcessor {
  forceFlush(): Promise<void> {
    return Promise.resolve();
  }

  shutdown(): Promise<void> {
    return Promise.resolve();
  }

  onEmit(logRecord: LogRecord, context?: Context): void {
    console.log('emitting');

    // Get trace context from the log record
    // const traceId = logRecord.spanContext?.traceId;
    // const spanId = logRecord.spanContext?.spanId;
    // if (traceId && spanId) {
    //   logRecord.attributes = {
    //     ...logRecord.attributes,
    //     dd: {
    //       trace_id: getDatadogTraceId(traceId),
    //       span_id: getDatadogSpanId(spanId)
    //     }
    //   };
    // }
  }
}

My goal is to add dd.trace_id and dd.span_id to the logs. I successfully do this to the spans with my DatadogSpanProcessor. But by your message I see that this is probably not possible with @vercel/otel correct? Is it possible without the otel package? As it seems logs forward to datadog even without installing the otel package.
