Is there a Logback Layout that Creates JSON Objects with Message Parameters as Attributes?

Question

I want to send log events to Loggly as JSON objects with parameterized string messages. Our project currently has a lot of code that looks like this:

String some

So for me I was trying to log execution times, I created a pojo called ExecutionTime with name, method, class, duration.

I was then able to create it:

ExecutionTime time = new ExecutionTime("Controller Hit", methodName, className, sw.getTotalTimeMillis());

For logging I then used:

private final Logger logger = LoggerFactory.getLogger(this.getClass());
logger.info(append("metric", time), time.toString());

Make sure you have:

import static net.logstash.logback.marker.Markers.append;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

This will log something like this:

{  
   "ts":"2017-02-16T07:41:36.680-08:00",
   "msg":"ExecutionTime [name=Controller Hit, method=setupSession, className=class com.xxx.services.controllers.SessionController, duration=3225]",
   "logger":"com.xxx.services.metrics.ExecutionTimeLogger",
   "level":"INFO",
   "metric":{  
      "name":"Controller Hit",
      "method":"setupSession",
      "className":"class com.xxx.services.controllers.SessionController",
      "duration":3225
   }
}

Might be a different set up as I was using logback-spring.xml to output my logs to json:

    
    
    
        app/logs/${PROJECT_ID}.json.log
        
            
                ts
                msg
                [ignore]
                [ignore]
                logger
                [ignore]
            
        
        
            10
            app/logs/${PROJECT_ID}.json.log.%i
