Doesn't redis generate traces automatically

[Chaofan1014]

main.ts

import { NestFactory } from '@nestjs/core';
import { Resource } from '@opentelemetry/resources';
import { BatchSpanProcessor, NodeTracerProvider, TraceIdRatioBasedSampler } from '@opentelemetry/sdk-trace-node';
import { Span } from '@opentelemetry/api';
import { Test3AppModule } from './test3-app.module';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-grpc';
import { registerInstrumentations } from '@opentelemetry/instrumentation';
import { HttpInstrumentation } from '@opentelemetry/instrumentation-http';
import { IORedisInstrumentation } from '@opentelemetry/instrumentation-ioredis';
import { ConsoleSpanExporter, SimpleSpanProcessor } from '@opentelemetry/sdk-trace-base';

async function bootstrap() {
  const resource = new Resource({
    'service.name': 'test3-app',
  });
  const provider = new NodeTracerProvider({
    resource: resource,
    sampler: new TraceIdRatioBasedSampler(1.0), 
  });


  provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
  
  const collectorOptions = { url: 'http://localhost:4317' };
  const exporter = new OTLPTraceExporter(collectorOptions);
  provider.addSpanProcessor(new BatchSpanProcessor(exporter));

  provider.register();

  registerInstrumentations({
    instrumentations: [
      new HttpInstrumentation(),
      new IORedisInstrumentation({
        requestHook: (span: Span, request: any) => {
          console.log('IORedis requestHook', request);
        },
        requireParentSpan: true,
      }),
    ],
  });

  const app = await NestFactory.create(Test3AppModule);
  await app.listen(3000);
}
bootstrap();

service.ts

import { Injectable } from '@nestjs/common';
import { Redis } from 'ioredis';

@Injectable()
export class Test3AppService {
  private readonly redis: Redis;

  constructor() {
    this.redis = new Redis('redis://localhost:31379');
  }

  async getHello(): Promise<string> {
    await this.redis.set('mykey', 'value');
    await this.redis.zadd('sortedSet', 1, 'one', 2, 'dos', 4, 'quatro', 3, 'three');
    return 'Hello World!';
  }
}

In the end, only http trace information is generated, redis has no information.

After I added instrumentation-pg, it can also be generated, but redis has not automatically generated.

"ioredis": "^5.5.0",
"@opentelemetry/instrumentation-ioredis": "0.47.1",
It would be appreciated if someone could help.

Sorry, the problem has been solved. For the nest framework I'm using, the root cause is that replacement modules are lazy-loaded
