func Fingerprint

func Fingerprint(input string, clusterManager *TrieClusterManager) (fingerprint int64, level string, js map[string]any, err error)

func GetExceptionMessage

func GetExceptionMessage(sr ptrace.Span) string

func GetFingerprintAttribute

func GetFingerprintAttribute(l pcommon.Map) int64

func GetFromResource

Types

type Fingerprinter

type Fingerprinter interface {
	IsWord(word string) bool
	Fingerprint(input string, clusterManager *TrieClusterManager) (fingerprint int64, level string, js map[string]any, err error)
	TokenizeInput(input string) (*TokenSeq, string, map[string]any, error)
}

type Option

type Option func(*fingerprinterImpl)

func WithMaxTokens

func WithMaxTokens(maxlen int) Option

type TokenSeq

type TokenSeq struct {
	Index    int
	Items    []string
	JsonKeys []string
}

TokenSeq represents a sequence of tokens extracted from log input. Items contains the tokenized pattern elements (e.g., ["<Loglevel>", "received", "<Path>"]). JsonKeys contains the dot-notation paths of any JSON keys found in the input.

type TrieClusterManager

type TrieClusterManager struct {
	// contains filtered or unexported fields
}

TrieClusterManager maps full token-prefixes to per-node leafClusterers.

func NewTrieClusterManager

func NewTrieClusterManager(threshold float64) *TrieClusterManager
