> Implement a meta query statistics metrics source, created whenever a 
> regionserver starts hosting meta, removed when meta hosting moves. Provide 
> views on top tables by request counts, top meta rowkeys by request count, top 
> clients making requests by their hostname. 
> Can be implemented as a coprocessor.
