Method Detail

get

@UnstableApi
public static RequestMetrics get()

Returns a RequestMetrics which can be used to enable recording of HttpClientMetrics on an InstrumenterBuilder.

start

public io.opentelemetry.context.Context start(io.opentelemetry.context.Context context,
                                              io.opentelemetry.api.common.Attributes startAttributes,
                                              long startNanos)

Description copied from interface: RequestListener

Listener method that is called at the start of a request. If any state needs to be kept between the start and end of the request, e.g., an in-progress span, it should be added to the passed in Context and returned.

Specified by:

start in interface RequestListener

startNanos - The nanosecond timestamp marking the start of the request. Can be used to compute the duration of the entire operation.

end

public void end(io.opentelemetry.context.Context context,
                io.opentelemetry.api.common.Attributes endAttributes,
                long endNanos)

Description copied from interface: RequestListener

Listener method that is called at the end of a request.

Specified by:

end in interface RequestListener

endNanos - The nanosecond timestamp marking the end of the request. Can be used to compute the duration of the entire operation.
