Package io.vertx.core.spi.metrics

## Interface DatagramSocketMetrics

- All Superinterfaces:
    `Metrics`, `NetworkMetrics<Void>`

      public interface DatagramSocketMetrics
      extends NetworkMetrics<Void>

  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.

  ### Event loop context

  Unless specified otherwise, all the methods on this object including the methods inherited from the super interfaces are invoked with the thread of the http server and therefore are the same than the `VertxMetrics` `createMetrics` method that created and returned this metrics object.

  ### Worker context

  Unless specified otherwise, all the methods on this object including the methods inherited from the super interfaces are invoked with a worker thread.
