func HandlerFormatter ¶

func HandlerFormatter(operation string, r *http.Request) string

HandlerFormatter is a span formatter that may be provided to otelhttp.WithSpanNameFormatter to include the component and url path in the span names generated by otelhttp.NewHandler.

func NewTransport ¶

func NewTransport(rt http.RoundTripper) http.RoundTripper

NewTransport wraps the provided http.RoundTripper with one that automatically adds spans for each http request.

Note: special care has been taken to ensure that the returned http.RoundTripper has a CloseIdleConnections method because the otelhttp.Transport does not implement it: https://github.com/open-telemetry/opentelemetry-go-contrib/issues/3543. Once the issue is resolved the wrapper may be discarded.

func NewTransportWithInner ¶

func NewTransportWithInner(rt http.RoundTripper, inner http.RoundTripper) http.RoundTripper

NewTransportWithInner wraps the provided http.RoundTripper with one that automatically adds spans for each http request. The inner round tripper is used to close idle connections when rt.CloseIdleConnections isn't implemented for the rt provided.

Note: special care has been taken to ensure that the returned http.RoundTripper has a CloseIdleConnections method because the otelhttp.Transport does not implement it: https://github.com/open-telemetry/opentelemetry-go-contrib/issues/3543. Once the issue is resolved the wrapper may be discarded.
