Reproduction Example/SDK Setup

PinoIntegration and enableLogs:true are set in the SDK initialisation

Two code examples.
From a Discord thread.

// Internal log method with type-safe logging
  private log(level: LogLevel, message: string, data?: any) {
    const parsedData = this.safeJson(data); // Parse data to JSON


    const logEntry: StandardLog = {
      level,
      timestamp: dateNow(),
      requestId: this.requestId,
      message,
      userId: this.userId,
      data: parsedData === null ? undefined : parsedData, // Set data if parsedData is not null
    };


    // Use the correct Pino method based on the log level
    switch (level) {
      case "trace":
        this.logger.trace(logEntry);
        break;
      case "debug":
        this.logger.debug(logEntry);
        break;
      case "info":
        this.logger.info(logEntry);
        break;
      case "warn":
        this.logger.warn(logEntry);
        break;
      case "error":
        this.logger.error(logEntry);
        break;
      case "fatal":
        this.logger.fatal(logEntry);
        break;
      default:
        this.logger.info(logEntry); // Default to info if level is not recognized
        break;
    }
  }

From an internal support ticket :
The logger is set-up as a Sentry module.

export const PinoHttpModule = LoggerModule.forRootAsync({...})

@Module({...
PinoHttpModule,
...})
export class AppModule {

The app startup code:

const pinoLogger = app.get(PinoLogger);
app.useLogger(pinoLogger);

//Send the log
private readonly logger = new Logger(MyService.name);
...
this.logger.log('log msg');

Steps to Reproduce

Use the example codes above to send logs to Sentry.

Expected Result

Logs are sent to Sentry and visible on the logs page.

Actual Result

No logs are reported.

Quick tests with simple logs (logger.info("Info log")) are sent correctly. Might be an integration's limitation where more complex logs are dropped.

My example that works:

//instrument.js
const Sentry = require("@sentry/node");

Sentry.init({
  debug:true,
  dsn: "...",
  integrations: [
    Sentry.pinoIntegration({ 
      log: { levels: ["info", "warn", "error"] }
    })
  ],
  enableLogs: true,
});

//script
require("./instrument");

const logger = require('pino')

logger.info('hello world')
