Package io.vertx.core.spi.metrics

Interface HttpServerMetrics<R,W,S>

All Superinterfaces:

Metrics, NetworkMetrics<S>, TCPMetrics<S>

public interface HttpServerMetrics<R,W,S>
extends TCPMetrics<S>

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.

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.

default void	requestEnd(R requestMetric, HttpRequest request, long bytesRead)	Called when an http server request has ended.
default void	requestReset(R requestMetric)	Called when the http server request couldn't complete successfully, for instance the connection was closed before the response was sent.
default void	requestRouted(R requestMetric, String route)	Called when a routing layer indicates a request has been routed.
default void	responseBegin(R requestMetric, HttpResponse response)	Called when an http server response begins.

Method Detail

requestBegin

default R requestBegin(S socketMetric,
                       HttpRequest request)

Called when an http server request begins. Vert.x will invoke responseEnd(R, io.vertx.core.spi.observability.HttpResponse, long) when the response has ended or requestReset(R) if the request/response has failed before.

Parameters:

socketMetric - the socket metric

request - the http server reuqest

Returns:

the request metric

requestEnd

default void requestEnd(R requestMetric,
                        HttpRequest request,
                        long bytesRead)

Called when an http server request has ended.

Parameters:

requestMetric - the request metric

request - the same HttpRequest provided in the initial response callback

bytesRead - the total number of bytes read

requestReset

default void requestReset(R requestMetric)

Called when the http server request couldn't complete successfully, for instance the connection was closed before the response was sent.

Parameters:

requestMetric - the request metric

responseBegin

default void responseBegin(R requestMetric,
                           HttpResponse response)

Called when an http server response begins.

Parameters:

requestMetric - the request metric

response - the http server request

responsePushed

default R responsePushed(S socketMetric,
                         HttpMethod method,
                         String uri,
                         HttpResponse response)

Called when an http server response is pushed.

Parameters:

socketMetric - the socket metric

method - the pushed response method

uri - the pushed response uri

response - the http server response @return the request metric

responseEnd

default void responseEnd(R requestMetric,
                         HttpResponse response,
                         long bytesWritten)

Called when an http server response has ended.

Parameters:

requestMetric - the request metric

response - the same HttpResponse provided in the initial response callback

bytesWritten - the total number of bytes written

connected

default W connected(S socketMetric,
                    R requestMetric,
                    ServerWebSocket serverWebSocket)

Called when a server web socket connects.

Parameters:

socketMetric - the socket metric

requestMetric - the request metric

serverWebSocket - the server web socket

Returns:

the server web socket metric

disconnected

default void disconnected(W serverWebSocketMetric)

Called when the server web socket has disconnected.

Parameters:

serverWebSocketMetric - the server web socket metric

requestRouted

default void requestRouted(R requestMetric,
                           String route)

Called when a routing layer indicates a request has been routed.

Parameters:

requestMetric - the request metric

route - the route the request has been routed to
