Functions

func FlowList

func FlowList() (string, error)

FlowList runs the nfqlb flow-list commands and returns the output

func NewLb

func NewLb(options ...LbOption) (*nfqlb, error)

NewLb - Creates LB that implements a Stream in nfqlb as a shared mem lb

func NewLbFactory

func NewLbFactory(options ...Option) *nfqlbFactory

func NewNetfilterAdaptor

func NewNetfilterAdaptor(options ...Option) (*netfilterAdaptor, error)

Types

type FlowStats

type FlowStats struct {
	Flow         *nspAPI.Flow
	MatchesCount int
}

func GetFlowStats

func GetFlowStats() ([]*FlowStats, error)

GetFlowStats returns the list of currently configured flows in nfqlb together with their match count metric. The flow will contain only the flow name and stream name since nfqlb is not aware about parent names (conduit/trench).

func (*FlowStats) GetFlow

func (fs *FlowStats) GetFlow() *nspAPI.Flow

func (*FlowStats) GetMatchesCount

func (fs *FlowStats) GetMatchesCount() int

type LbOption

type LbOption func(o *lbOptions)

func WithLbName

func WithLbName(name string) LbOption

func WithMaglevM

func WithMaglevM(m int) LbOption

func WithMaglevN

func WithMaglevN(n int) LbOption

type Option

type Option func(o *nfoptions)

func WithNFQueue

func WithNFQueue(queue string) Option

func WithNFQueueFanout

func WithNFQueueFanout(fanout bool) Option
