Functions

func StatsFlowHash

func StatsFlowHash(r *FlowRecord) string

StatsFlowHash is a has function to hash flows

Types

type ContainerRecord

type ContainerRecord struct {
	ContextID string

	Tags      *policy.TagStore
	Event     string
}

ContainerRecord is a statistics record for a container

type DefaultCollector

type DefaultCollector struct{}

DefaultCollector implements a default collector infrastructure to syslog

func (*DefaultCollector) CollectContainerEvent

func (d *DefaultCollector) CollectContainerEvent(record *ContainerRecord)

CollectContainerEvent is part of the EventCollector interface.

func (*DefaultCollector) CollectFlowEvent

func (d *DefaultCollector) CollectFlowEvent(record *FlowRecord)

CollectFlowEvent is part of the EventCollector interface.

type EndPoint

type EndPoint struct {
	ID   string
	IP   string
	Port uint16
	Type EndPointType
}

EndPoint is a structure that holds all the endpoint information

type EndPointType

type EndPointType byte

EndPointType is the type of an endpoint (PU or an external IP address )

const (
	// Address indicates that the endpoint is an external IP address
	Address EndPointType = iota
	// PU indicates that the endpoint is a PU
	PU
)

func (*EndPointType) String

func (e *EndPointType) String() string

type EventCollector

type EventCollector interface {

	// CollectFlowEvent collect a  flow event.
	CollectFlowEvent(record *FlowRecord)

	// CollectContainerEvent collects a container events
	CollectContainerEvent(record *ContainerRecord)
}

EventCollector is the interface for collecting events.

type FlowRecord

type FlowRecord struct {
	ContextID   string
	Count       int
	Source      *EndPoint
	Destination *EndPoint
	Tags        *policy.TagStore
	Action      policy.ActionType
	DropReason  string
	PolicyID    string
}

FlowRecord describes a flow record for statistis
