func HTTPClientRequest ¶

func HTTPClientRequest(req *http.Request) []attribute.KeyValue

HTTPClientRequest returns trace attributes for an HTTP request made by a client. The following attributes are always returned: "http.url", "http.flavor", "http.method", "net.peer.name". The following attributes are returned if the related values are defined in req: "net.peer.port", "http.user_agent", "http.request_content_length", "enduser.id".

func HTTPClientRequestMetrics ¶

func HTTPClientRequestMetrics(req *http.Request) []attribute.KeyValue

HTTPClientRequestMetrics returns metric attributes for an HTTP request made by a client. The following attributes are always returned: "http.method", "net.peer.name". The following attributes are returned if the related values are defined in req: "net.peer.port".

func HTTPClientResponse ¶

func HTTPClientResponse(resp *http.Response) []attribute.KeyValue

HTTPClientResponse returns trace attributes for an HTTP response received by a client from a server. It will return the following attributes if the related values are defined in resp: "http.status.code", "http.response_content_length".

This does not add all OpenTelemetry required attributes for an HTTP event, it assumes ClientRequest was used to create the span with a complete set of attributes. If a complete set of attributes can be generated using the request contained in resp. For example:

append(HTTPClientResponse(resp), ClientRequest(resp.Request)...)

func HTTPClientStatus ¶

func HTTPClientStatus(code int) (codes.Code, string)

HTTPClientStatus returns a span status code and message for an HTTP status code value received by a client.

func HTTPServerRequest ¶

func HTTPServerRequest(server string, req *http.Request) []attribute.KeyValue

HTTPServerRequest returns trace attributes for an HTTP request received by a server.

The server must be the primary server name if it is known. For example this would be the ServerName directive (https://httpd.apache.org/docs/2.4/mod/core.html#servername) for an Apache server, and the server_name directive (http://nginx.org/en/docs/http/ngx_http_core_module.html#server_name) for an nginx server. More generically, the primary server name would be the host header value that matches the default virtual host of an HTTP server. It should include the host identifier and if a port is used to route to the server that port identifier should be included as an appropriate port suffix.

If the primary server name is not known, server should be an empty string. The req Host will be used to determine the server instead.

The following attributes are always returned: "http.method", "http.scheme", "http.flavor", "http.target", "net.host.name". The following attributes are returned if they related values are defined in req: "net.host.port", "net.sock.peer.addr", "net.sock.peer.port", "http.user_agent", "enduser.id", "http.client_ip".

func HTTPServerRequestMetrics ¶

func HTTPServerRequestMetrics(server string, req *http.Request) []attribute.KeyValue

HTTPServerRequestMetrics returns metric attributes for an HTTP request received by a server.

The server must be the primary server name if it is known.

The following attributes are always returned: "http.method", "http.scheme", "http.flavor", "net.host.name". The following attributes are returned if they related values are defined in req: "net.host.port".

func HTTPServerStatus ¶

func HTTPServerStatus(code int) (codes.Code, string)

HTTPServerStatus returns a span status code and message for an HTTP status code value returned by a server. Status codes in the 400-499 range are not returned as errors.

func NetTransport ¶

func NetTransport(network string) attribute.KeyValue

NetTransport returns a trace attribute describing the transport protocol of the passed network. See the net.Dial for information about acceptable network values.
