io.vertx.core.spi.metrics

Interface TCPMetrics<S>

All Superinterfaces:

Metrics, NetworkMetrics<S>

All Known Subinterfaces:

HttpClientMetrics<R,W,S>, HttpServerMetrics<R,W,S>

public interface TCPMetrics<S>
extends NetworkMetrics<S>

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.

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 client/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.
