:chart_with_upwards_trend: Capturing JVM- and application-level metrics. So you know what's going on.
Role in this project:Backend Developer
Backend DeveloperContributions:232 commits, 211 PRs, 135 pushes in 5 years 6 months
Contributions summary:Ryan's commits primarily focused on enhancing the `metrics-spring` module within the `dropwizard/metrics` repository. They introduced and refined several BeanPostProcessors to instrument Spring applications, particularly for exception handling and method timing using the Metrics library. Key contributions include adding functionality to register methods with `@Timed`, `@Metered`, `@ExceptionMetered` and `@Gauge` annotations, demonstrating a strong understanding of Spring AOP and the Metrics API. Further, they added a `<metrics:jmx-reporter>` tag and `proxy-target-class` attribute to customize instrumentation behaviour.
