    const fileTransport = new logger.FileTransport('/var/log/full_app.log');
    appLogger.addTransport(fileTransport);
    
    appLogger.info('Application is starting...');
    
    // Simulate some application activities

    try {
      // Simulating operation
      throw new Error('Simulated error');
