func Middleware

func Middleware(service string, opts ...Option) mux.MiddlewareFunc

Middleware sets up a handler to start tracing the incoming requests. The service parameter should describe the name of the (virtual) server handling the request.

func SemVersion deprecated added in v0.24.0

func SemVersion() string

SemVersion is the semantic version to be supplied to tracer/meter creation.

Deprecated: Use Version instead.

func Version added in v0.24.0

func Version() string

Version is the current release version of the gorilla/mux instrumentation.


type Filter added in v0.44.0

type Filter func(*http.Request) bool

Filter is a predicate used to determine whether a given http.request should be traced. A Filter must return true if the request should be traced.

type Option

type Option interface {
	// contains filtered or unexported methods

Option specifies instrumentation configuration options.

func WithFilter added in v0.44.0

func WithFilter(f Filter) Option

WithFilter adds a filter to the list of filters used by the handler. If any filter indicates to exclude a request then the request will not be traced. All filters must allow a request to be traced for a Span to be created. If no filters are provided then all requests are traced. Filters will be invoked for each processed request, it is advised to make them simple and fast.

func WithPropagators

func WithPropagators(propagators propagation.TextMapPropagator) Option

WithPropagators specifies propagators to use for extracting information from the HTTP requests. If none are specified, global ones will be used.

func WithPublicEndpoint added in v0.41.1

func WithPublicEndpoint() Option

WithPublicEndpoint configures the Handler to link the span with an incoming span context. If this option is not provided, then the association is a child association instead of a link.

func WithPublicEndpointFn added in v0.41.1

func WithPublicEndpointFn(fn func(*http.Request) bool) Option

WithPublicEndpointFn runs with every request, and allows conditionnally configuring the Handler to link the span with an incoming span context. If this option is not provided or returns false, then the association is a child association instead of a link. Note: WithPublicEndpoint takes precedence over WithPublicEndpointFn.

func WithSpanNameFormatter added in v0.38.0

func WithSpanNameFormatter(fn func(routeName string, r *http.Request) string) Option

WithSpanNameFormatter specifies a function to use for generating a custom span name. By default, the route name (path template or regexp) is used. The route name is provided so you can use it in the span name without needing to duplicate the logic for extracting it from the request.

func WithTracerProvider

func WithTracerProvider(provider oteltrace.TracerProvider) Option

WithTracerProvider specifies a tracer provider to use for creating a tracer. If none is specified, the global provider is used.
