Text from NEWS.txt:
bq. Support for alternative metrics exporters has been added. To use them, the 
appropriate libraries need to be placed in the lib directory. Cassandra will 
load the class given in the system property cassandra.metricsExporter and 
instantiate it by calling the constructor taking an instance of 
com.codahale.metrics.MetricRegistry. If the provided class implements 
java.io.Closeable, its close() method will be called on shutdown.

> Export metrics for prometheus in its native format

>
> https://github.com/snazy/prometheus-metrics-exporter allows to export 
> codahale metrics for prometheus.io. In order to integrate this, a minor 
> change to C* is necessary to load the library.
> This eliminates the need to use the additional graphite-exporter tool and 
> therefore also allows prometheus to track the up/down status of C*.
> (Will provide the patch soon)
