>   public void start() {
>     //All the Ratis metrics (registered from now) will be published via JMX and
>     //via the prometheus exporter (used by the /prom servlet
>     MetricRegistries.global()
>         .addReporterRegistration(MetricsReporting.jmxReporter());
>     MetricRegistries.global().addReporterRegistration(
