Overview

Package aws provides functions to trace aws/aws-sdk-go (https://github.com/aws/aws-sdk-go).

Example

To start tracing requests, wrap the AWS session.Session by invoking awstrace.WrapSession.

package main

import (
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/s3"

	awstrace "gopkg.in/DataDog/dd-trace-go.v1/contrib/aws/aws-sdk-go/aws"
)

func main() {
	cfg := aws.NewConfig().WithRegion("us-west-2")
	sess := session.Must(session.NewSession(cfg))
	sess = awstrace.WrapSession(sess)

	s3api := s3.New(sess)
	s3api.CreateBucket(&s3.CreateBucketInput{
		Bucket: aws.String("some-bucket-name"),
	})
}

func WithAnalyticsRate

func WithAnalyticsRate(rate float64) Option

WithAnalyticsRate sets the sampling rate for Trace Analytics events correlated to started spans.

func WithServiceName

func WithServiceName(name string) Option

WithServiceName sets the given service name for the dialled connection. When the service name is not explicitly set it will be inferred based on the request to AWS.
