>     DynamicMBean mBean = metricRegistry(srv.name(), "io", "discovery");
>     mBean.getMBeanInfo();
> }
> {code}
> The main reason: JMX exporter assumes that each metric must starts with the name of the registry  it belongs to (see MetricRegistryMBean#getMBeanInfo), but discovery metrics do not obey this naming convection (see TcpDiscoveryStatistics/ZookeeperDiscoveryStatistics).
