What are these informations shown at the bottom?

All logs of your systems are also shown as messages (at the bottom right of System Designer).

How can I log informations?

logger APIs are inspired by Log4J, so you have:

this.require('logger').debug('this is a debug message'');

this.require('logger').info('this is an info message'');

this.require('logger').warn('this is a warning message'');

this.require('logger').error('this is an error message'');
