## Introduction

uptrace-go is an OpenTelemery Go distribution configured to export

[traces](https://uptrace.dev/opentelemetry/distributed-tracing.html) and

[metrics](https://uptrace.dev/opentelemetry/metrics.html) to Uptrace.

## Quickstart

Install uptrace-go:

```bash

go get github.com/uptrace/uptrace-go

```

Run the [basic example](example/basic) below using the DSN from the Uptrace project settings page.

```go

package main

import (

	"context"

	"errors"

	"fmt"

	"go.opentelemetry.io/otel"

	"go.opentelemetry.io/otel/attribute"

	"github.com/uptrace/uptrace-go/uptrace"

)

func main() {

	ctx := context.Background()

	// Configure OpenTelemetry with sensible defaults.

	uptrace.ConfigureOpentelemetry(

		// copy your project DSN here or use UPTRACE_DSN env var

		// uptrace.WithDSN("https://@uptrace.dev/"),

		uptrace.WithServiceName("myservice"),

		uptrace.WithServiceVersion("1.0.0"),

	)

	// Send buffered spans and free resources.

	defer uptrace.Shutdown(ctx)

	// Create a tracer. Usually, tracer is a global variable.

	tracer := otel.Tracer("app_or_package_name")

	// Create a root span (a trace) to measure some operation.

	ctx, main := tracer.Start(ctx, "main-operation")

	// End the span when the operation we are measuring is done.

	defer main.End()

	// The passed ctx carries the parent span (main).

	// That is how OpenTelemetry manages span relations.

	_, child1 := tracer.Start(ctx, "GET /posts/:id")

	child1.SetAttributes(

		attribute.String("http.method", "GET"),

		attribute.String("http.route", "/posts/:id"),

		attribute.String("http.url", "http://localhost:8080/posts/123"),

		attribute.Int("http.status_code", 200),

	)

	child1.RecordError(errors.New("error1"))

	child1.End()

	_, child2 := tracer.Start(ctx, "SELECT")

	child2.SetAttributes(

		attribute.String("db.system", "mysql"),

		attribute.String("db.statement", "SELECT * FROM posts LIMIT 100"),

	)

	child2.End()

	fmt.Printf("trace: %s\n", uptrace.TraceURL(main))

}

```
