I will try to describe something in quick. There is an interface for 
log backend and logger. Some default implementations of log backends 
are provided by Flow. You can have look at available backends in class 
namespace \TYPO3\Flow\Log\Backend. Then there is a default 
implementation \TYPO3\Flow\Log\Logger. The 
\TYPO3\Flow\Log\LoggerFactory is used to instantiate the logger.

1. Have look at TYPO3.Flow/Configuration/Settings.yaml and search for "log:"
2. Have look at TYPO3.Flow/Configuration/Objects.yaml and search for "Logger"
3. For an example of how to use logger have look at class 
\TYPO3\Flow\Security\Aspect\LoggingAspect

If you correctly follow #1 to 3 in your package then you can get your 
PersistenceLogger working in few minutes :)
