Functions ¶

func ComputeHash ¶

func ComputeHash(flowLog config.GenericMap, keyDefinition api.KeyDefinition, hasher hash.Hash64, metrics *metricsType) (totalHashType, error)

ComputeHash computes the hash of a flow log according to keyDefinition. Two flow logs will have the same hash if they belong to the same connection.

func NewConnBuilder ¶

func NewConnBuilder(metrics *metricsType) *connBuilder

func NewConnectionTrack ¶

func NewConnectionTrack(opMetrics *operational.Metrics, params config.StageParam, clock clock.Clock) (extract.Extractor, error)

NewConnectionTrack creates a new connection track instance
