package echo

import "gopkg.in/DataDog/dd-trace-go.v1/contrib/labstack/echo"

Package echo provides functions to trace the labstack/echo package (https://github.com/labstack/echo).

To start tracing requests, add the trace middleware to your echo router.


r := echo.New()

// Use the tracer middleware with your desired service name.

// Set up an endpoint.
r.GET("/hello", func(c echo.Context) error {
    return c.String(200, "hello world!")

// ...and listen for incoming requests

An example illustrating tracing a child operation within the main context.


// Create a new instance of echo
r := echo.New()

// Use the tracer middleware with your desired service name.

// Set up some endpoints.
r.GET("/image/encode", func(c echo.Context) error {
    // create a child span to track an operation
    span, _ := tracer.StartSpanFromContext(c.Request().Context(), "image.encode")

    // encode an image ...

    // finish the child span

    return c.String(200, "ok!")
