---------------------------------

Hi [~Zentol],
I checked your code, it's very good. 
but, I do not know what else need to be modified?
I just found via *extends AbstractReporter implements Scheduled*, the 
implementation would be easier. 

> Implement a slf4j metric reporter

> For debugging purpose it would be very useful to have a log4j metric 
> reporter. If you don't want to setup a metric backend you currently have to 
> rely on JMX, which a) works a bit differently than other reporters (for 
> example it doesn't extend AbstractReporter) and b) makes it a bit tricky to 
> analyze results as metrics are cleaned up once a job finishes.
