Interface BaseLogger

Set this property to the desired logging level. In order of priority, available levels are:

• 'fatal'
• 'error'
• 'warn'
• 'info'
• 'debug'
• 'trace'

The logging level is a minimum level. For instance if logger.level is 'info' then all 'fatal', 'error', 'warn', and 'info' logs will be enabled.

You can pass 'silent' to disable logging.

Log at 'fatal' level the given msg. If the first argument is an object, all its properties will be included in the JSON line. If more args follows msg, these will be used to format msg using util.format.
