Metrics exporter for twitter server, exposing prometheus metrics.

Based on the blog post and code from Footballradar

• Integrated to the admin UI
• Metrics are exposed on the admin port /metrics http endpoint.
• The service is detached from the main thread pool of the rest of the app just like the /admin/metrics.json.
• Exported histograms include count, sum, min, max, avg and quantile data just like in Finagle

Include it in your project by adding the following to your build.sbt:

libraryDependencies += "com.github.kovszilard" %% "twitter-server-prometheus" % "19.10.0"

Once you have the SBT dependency, you can mix in the PrometheusExporter trait to your App.

object MyApp extends TwitterServer with PrometheusExporter {
  // ...
}
