XD-2107&1048: --nameExpression for metrics & --incrementExpression for agg-counter

Can you refer to a specific section from that book?

I was thinking that it would be sufficient to have the alpha set for a given counter instance even if that is handling multiple counter (names) at runtime. If someone really needs a different alpha value, nothing stops them from creating a new counter instance. But, I may change my mind once I read what you read ;)
