Codahale指标和Dropwizard指标之间的差异

Question

I'm new to Java. While exploring the ways of monitoring Cassandra, I found out( https://cassandra.apache.org/doc/latest/operating/metrics.html ) 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?

Answer 1

The Metrics library have changed its package naming with versions as its changed hands in ownership a bit

yammer->codahale->dropwizard

They are all same library but dropwizard is the more up to date version
