Just came over this myself and found an article with a few recommandations on logging.

If you use maven put this dependency into pom.xml

    net.logstash.logback
    logstash-logback-encoder
    3.4

And put something like this into logback.xml

    
    
        logs/${PROJECT_ID}.json
        
        
            1
            logs/${PROJECT_ID}.json.%i
        
        
            1MB
        
    
    
        
    
    
        
    

This creates example.json file under logs/. The file is rolled once when it reaches 1MB in size.

LOGGER.debug(append("object", someObject), "log message");
