title: Difference between Codahale metrics and Dropwizard metrics
body: <p>I'm new to Java. While exploring the ways of monitoring Cassandra, I found out(<a href="https://cassandra.apache.org/doc/latest/operating/metrics.html" rel="noreferrer">https://cassandra.apache.org/doc/latest/operating/metrics.html</a>) that "Metrics in Cassandra are managed using the Dropwizard Metrics library". However, at several places I've read about Codahale Metrics which has got me confused regarding the difference/relationship between the two.
  Are these different libraries doing the same thing or is it that what's called as dropwizard metrics used to be called as Codahale Metrics earlier? </p>
