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 (
	awstrace "github.com/DataDog/dd-trace-go/v2/contrib/aws/aws-sdk-go/aws"

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

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"),
	})
}

Functions

func WrapSession

func WrapSession(s *session.Session, opts ...Option) *session.Session

WrapSession wraps a session.Session, causing requests and responses to be traced.

Types

type Option

type Option func(*config)

Option represents an option that can be passed to Dial.

func WithAnalytics

func WithAnalytics(on bool) Option

WithAnalytics enables Trace Analytics for all started spans.

func WithAnalyticsRate

func WithAnalyticsRate(rate float64) Option

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

func WithErrorCheck

func WithErrorCheck(fn func(err error) bool) Option

WithErrorCheck specifies a function fn which determines whether the passed error should be marked as an error. The fn is called whenever an aws operation finishes with an error.

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.
