Functions

func CreateHTTPTriggerEvent

func CreateHTTPTriggerEvent(wrapperTracer tracer.Tracer, request *http.Request, resourceName string) *protocol.Event

CreateHTTPTriggerEvent creates an HTTP trigger event

Types

type ClientWrapper

type ClientWrapper struct {
	http.Client

	// MetadataOnly flag overriding the configuration
	MetadataOnly bool
	// contains filtered or unexported fields
}

ClientWrapper is Epsagon's wrapper for http.Client

func Wrap

func Wrap(c http.Client, args ...context.Context) ClientWrapper

Wrap wraps an http.Client to Epsagon's ClientWrapper

func (*ClientWrapper) Do

func (c *ClientWrapper) Do(req *http.Request) (resp *http.Response, err error)

Do wraps http.Client's Do

func (*ClientWrapper) Get

func (c *ClientWrapper) Get(rawUrl string) (resp *http.Response, err error)

Get wraps http.Client.Get

func (*ClientWrapper) Head

func (c *ClientWrapper) Head(rawUrl string) (resp *http.Response, err error)

Head wraps http.Client.Head

func (*ClientWrapper) Post

func (c *ClientWrapper) Post(
	rawUrl string, contentType string, body io.Reader) (resp *http.Response, err error)

Post wraps http.Client.Post

func (*ClientWrapper) PostForm

func (c *ClientWrapper) PostForm(
	rawUrl string, data url.Values) (resp *http.Response, err error)

PostForm wraps http.Client.PostForm

type HandlerFunction

type HandlerFunction func(http.ResponseWriter, *http.Request)

HandlerFunction is a generic http handler function

func WrapHandleFunc

func WrapHandleFunc(
	config *epsagon.Config, handler HandlerFunction, names ...string) HandlerFunction

WrapHandleFunc wraps a generic http.HandleFunc handler function with Epsagon Last two optional paramerts are the name of the handler (will be the resource name of the events) and an optional hardcoded hostname

type TracingTransport

type TracingTransport struct {
	// MetadataOnly flag overriding the configuration
	MetadataOnly bool
	// contains filtered or unexported fields
}

TracingTransport is the RoundTripper implementation that traces HTTP calls

func NewTracingTransport

func NewTracingTransport(args ...context.Context) *TracingTransport

func NewWrappedTracingTransport

func NewWrappedTracingTransport(rt http.RoundTripper, args ...context.Context) *TracingTransport

func (*TracingTransport) RoundTrip

func (t *TracingTransport) RoundTrip(req *http.Request) (resp *http.Response, err error)

RoundTrip implements the RoundTripper interface to trace HTTP calls

type ValidationFunction

type ValidationFunction func(string, string) bool

type WrappedResponseWriter

type WrappedResponseWriter struct {
	http.ResponseWriter
	// contains filtered or unexported fields
}

WrappedResponseWriter is wrapping Resposne writer with Epsagon to enrich the trace with data from the response

func CreateWrappedResponseWriter

func CreateWrappedResponseWriter(rw http.ResponseWriter, resource *protocol.Resource) *WrappedResponseWriter

CreateWrappedResponseWriter creates a newWrappedResponseWriter

func (*WrappedResponseWriter) Header

func (w *WrappedResponseWriter) Header() http.Header

Header wrapper

func (*WrappedResponseWriter) UpdateResource
