Overview ¶
Package aws provides functions to trace aws/aws-sdk-go-v2 (https://github.com/aws/aws-sdk-go-v2).
Usage Example:
import (
"context"
"log"
"os"
"github.com/aws/aws-sdk-go-v2/aws"
awscfg "github.com/aws/aws-sdk-go-v2/config"
"github.com/aws/aws-sdk-go-v2/feature/s3/manager"
"github.com/aws/aws-sdk-go-v2/service/s3"
"github.com/aws/aws-sdk-go-v2/service/sqs"
awstrace "gopkg.in/DataDog/dd-trace-go.v1/contrib/aws/aws-sdk-go-v2/aws"
"gopkg.in/DataDog/dd-trace-go.v1/ddtrace/ext"
"gopkg.in/DataDog/dd-trace-go.v1/ddtrace/tracer"
)
func Example() {
awsCfg, err := awscfg.LoadDefaultConfig(context.Background())
if err != nil {
log.Fatalf(err.Error())
}
awstrace.AppendMiddleware(&awsCfg)
sqsClient := sqs.NewFromConfig(awsCfg)
sqsClient.ListQueues(context.Background(), &sqs.ListQueuesInput{})
}
// An example of the aws span inheriting a parent span from context.
func Example_context() {
cfg, err := awscfg.LoadDefaultConfig(context.TODO(), awscfg.WithRegion("us-west-2"))
if err != nil {
log.Fatalf("error: %v", err)
}
awstrace.AppendMiddleware(&cfg)
client := s3.NewFromConfig(cfg)
uploader := manager.NewUploader(client)
// Create a root span.
span, ctx := tracer.StartSpanFromContext(context.Background(), "parent.request",
tracer.SpanType(ext.SpanTypeWeb),
tracer.ServiceName("web"),
tracer.ResourceName("/upload"),
)
defer span.Finish()
// Open image file.
filename := "my_image.png"
file, err := os.Open(filename)
if err != nil {
log.Fatalf("error: %v", err)
}
defer file.Close()
uploadParams := &s3.PutObjectInput{
Bucket: aws.String("my_bucket"),
Key: aws.String(filename),
Body: file,
ContentType: aws.String("image/png"),
}
// Inherit parent span from context.
_, err = uploader.Upload(ctx, uploadParams)
if err != nil {
log.Fatalf("error: %v", err)
}
}

Functions ¶
func AppendMiddleware ¶
AppendMiddleware takes the aws.Config and adds the Datadog tracing middleware into the APIOptions middleware stack. See https://aws.github.io/aws-sdk-go-v2/docs/middleware for more information.
Types ¶
type Option ¶
Option represents an option that can be passed to Dial.
func WithAnalytics ¶
WithAnalytics enables Trace Analytics for all started spans.
func WithAnalyticsRate ¶
WithAnalyticsRate sets the sampling rate for Trace Analytics events correlated to started spans.
func WithErrorCheck ¶ added in v1.53.0
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 ¶
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.
