Functions

func CheckIsInferredSpan

func CheckIsInferredSpan(span *pb.Span) bool

CheckIsInferredSpan determines if a span belongs to a managed service or not _inferred_span.tag_source = "self" => managed service span _inferred_span.tag_source = "lambda" or missing => lambda related span

func CreateServiceMapping

func CreateServiceMapping(val string) map[string]string

func DetermineServiceName

func DetermineServiceName(serviceMapping map[string]string, specificKey string, genericKey string, defaultValue string) string

func FilterFunctionTags

func FilterFunctionTags(input map[string]string) map[string]string

FilterFunctionTags filters out DD tags & function specific tags

func GenerateSpanId

func GenerateSpanId() uint64

GenerateSpanId creates a secure random span id in specific scenarios, otherwise return a pseudo random id

func GetServiceMapping

func GetServiceMapping() map[string]string

This function gets a snapshot of the current service mapping without modifying it.

func IsInferredSpansEnabled

func IsInferredSpansEnabled() bool

IsInferredSpansEnabled is used to determine if we need to generate and enrich inferred spans for a particular invocation

func SetServiceMapping

func SetServiceMapping(newServiceMapping map[string]string)

SetServiceMapping sets the serviceMapping global variable, primarily for tests.

Types

type InferredSpan

type InferredSpan struct {
	Span    *pb.Span
	IsAsync bool
	// CurrentInvocationStartTime is the start time of the
	// current invocation not he inferred span. It is used
	// for async function calls to calculate the duration.
	CurrentInvocationStartTime time.Time
}

InferredSpan contains the pb.Span and Async information of the inferredSpan for the current invocation

func (*InferredSpan) AddTagToInferredSpan

func (inferredSpan *InferredSpan) AddTagToInferredSpan(key string, value string)

AddTagToInferredSpan is used to add new tags to the inferred span in inferredSpan.Span.Meta[]. Should be used before completing an inferred span.
