As per documentation, New Relic has built-in support for instrumenting Hystrix. I want to use these metrics generated by hystrix-metrics such as latencies and error rates, send these to New Relic and use them to monitor ext services for my app (very similar the hystrix-dashboard), but I could not find any relevant documentation apart from this
I am using the dropwizard framework for my app
So it looks like NR archived their Hystrix code as Netflix stopped developing it several years ago. https://docs.newrelic.com/docs/apm/agents/java-agent/instrumentation/extension-additional-instrumentation-modules/#hystrix-130
You can install the archived java addon module, but its not supported officially so it may or may not give you what you are looking for.
