# Instrumenting Gin with OpenTelemetry

# Prerequisites

  • Go 1.13+

# Introduction

In this tutorial we will instrument a basicopen in new window Gin app using OpenTelemetry instrumentation.

# Instrumenting Gin app

  • Step 1. Let's start by downloading the source code:
git clone https://github.com/uptrace/uptrace-go.git
cd example/gin
  • Step 2. Install uptrace-go and Gin instrumentation:
go get github.com/uptrace/uptrace-go
go get go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin
  • Step 3. Edit main.go to configure OpenTelemetry to export data to Uptrace:
import "github.com/uptrace/uptrace-go/uptrace"

	// copy your project DSN here or use UPTRACE_DSN env var
	DSN: "",
  • Step 4. Edit main.go to instrument the Gin app:
router := gin.Default()
UPTRACE_DSN="https://<token>@api.uptrace.dev/<project_id>" go run main.go

The full code is available at GitHubopen in new window.

# Instrumenting templates rendering

To instrument html/template rendering, use otelgin.HTML helper:

func exampleHandler(c *gin.Context) {
	otelgin.HTML(c, http.StatusOK, indexTmpl, gin.H{
		"foo": "bar",

# What is next?

By now, you should have a Django app with instrumented views. Next, instrumentopen in new window more operations (for example, database queries) or learn about OpenTelemetry API to create your own instrumentations.
