> CASSANDRA-4009  expanded the use of the metrics library which has a set of reporter modules
http://metrics.codahale.com/manual/core/#reporters  You can report to flat files, ganglia,
spit everything over http, etc.  The next step is a mechanism for using those reporters with
 o.a.c.metrics.  To avoid bundling everything I suggest following the mx4j approach of "enable
only if on classpath coupled with a reporter configuration file.
