Documentation

Overview

Package otelgin instruments the github.com/gin-gonic/gin package.

Currently there are two ways the code can be instrumented. One is instrumenting the routing of a received message (the Middleware function) and instrumenting the response generation through template evaluation (the HTML function).

• func HTML(c *gin.Context, code int, name string, obj interface{})

Functions

func HTML

func HTML(c *gin.Context, code int, name string, obj interface{})

HTML will trace the rendering of the template as a child of the span in the given context. This is a replacement for gin.Context.HTML function - it invokes the original function after setting up the span.

func Middleware

func Middleware(service string, opts ...Option) gin.HandlerFunc

Middleware returns middleware that will trace incoming requests. The service parameter should describe the name of the (virtual) server handling the request.

Types

type Option

type Option func(*config)

Option specifies instrumentation configuration options.

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 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.
