  VertxMetrics The main Vert.x metrics SPI which Vert.x will use internally.

- Classes in io.vertx.core.spi.metrics used by io.vertx.core.spi.metrics
  Class and Description
  ClientMetrics The client metrics SPI that Vert.x will use to call when client events occur.
  DatagramSocketMetrics The datagram/udp metrics SPI which Vert.x will use to call when each event occurs pertaining to datagram sockets. The thread model for the datagram socket depends on the actual context thats started the server.
  EventBusMetrics The event bus metrics SPI which Vert.x will use to call when each event occurs.
  HttpClientMetrics The http client metrics SPI that Vert.x will use to call when http client events occur. The thread model for the http server metrics depends on the actual context thats started the server.
  HttpServerMetrics The http server metrics SPI that Vert.x will use to call when each http server event occurs. The thread model for the http server metrics depends on the actual context thats started the server.
  Metrics The metrics interface is implemented by metrics providers that wants to provide monitoring of Vert.x core.
  NetworkMetrics An SPI used internally by Vert.x to gather metrics on a net socket which serves as a base class for TCP or UDP.
  PoolMetrics An SPI used internally by Vert.x to gather metrics on pools used by Vert.x (execute blocking, worker verticle or data source).
  TCPMetrics An SPI used internally by Vert.x to gather metrics on a net socket which serves as a base class for things like HttpServer and HttpClient, all of which serve TCP connections. The thread model for the tcp metrics depends on the actual context thats created the client/server.
