We use Coda Hale's (Dropwizard) Metrics library and there is no known performance issues with it. See following threads in metrics-user group: "Overhead of collecting performance stats and publishing in JMX" https://groups.google.com/d/msg/metrics-user/CHk14cMmLsM/HXsZUDSZdMcJ "metrics performance" https://groups.google.com/d/msg/metrics-user/fb-hy6TQJ9g/6AQ1NMUlllEJ One concern would be periodic reporting to database by the JDBC reporter we developed. It runs in a scheduled executor and I guess it shouldn't have much impact on the server. We will be doing performance tests with MB and we can confirm whether there is an overhead with Metrics.
