Event emitter -- on logger or transport

I’m having an issue catching ‘logged’ notifications and I’m not sure if I’m doing something wrong because the documentation is a little confusing on this point.

It says the winston.Logger is an EventEmitter:

Each instance of winston.Logger is also an instance of an EventEmitter. A logged event will be raised each time a transport successfully logs a message:

but then show an example of listening to events on a winston.transport:

const transport = new winston.transports.Console();
const logger = winston.createLogger({
  transports: [transport];
});

transport.on('logged', function (info) {
  // `info` log message has now been logged
});

logger.info('CHILL WINSTON!', { seriously: true });

Can (or should) we listen to events on the trasport or the logger?

I’ve just ran a quick test here and I only could have it working if using the following setup:

• Event logged
• Listen on the transport (not on the logger)
• The transport is other than the Console

Wouldn’t bubbling the ‘logged’ event from each transport cause several events with same data?
