It's very possible to do something like this in logback. Here's an example configuration:

    
        logfile.log

            %-4relative [%thread] %-5level %logger{35} - %msg %n
        
    
    
        analytics.log
        true
        
            %-4relative [%thread] %-5level %logger{35} - %msg %n
        
    
    
    
        
    
    
        
    

Then you'd setup two separate loggers, one for everything and one to log analytics data like so:

Logger analytics = LoggerFactory.getLogger("analytics");
