I've recently pushed up a new project to github, which we've named Under Siege. It's a java agent for reporting Cassandra metrics to statsd. We've in the process of deploying it to our production clusters. Tested against Cassandra 1.2.11. The metrics library seems to change on every release of C*, so I'm not sure what'll happen if you deploy against a different version. Might need to mvn package against the same version of metrics.
