var (
	// PeriodicPollingPeriod between statistics reads
	// TODO  should be configurable
	PeriodicPollingPeriod = time.Second * 5

DefaultPlugin is a default instance of IfPlugin.

Types

type API

type API interface {
	// GetInterfaceIndex gives read-only access to map with metadata of all configured
	// VPP interfaces.
	GetInterfaceIndex() ifaceidx.IfaceMetadataIndex

	// GetDHCPIndex gives read-only access to (untyped) map with DHCP leases.
	// Cast metadata to "github.com/ligato/vpp-agent/api/models/vpp/interfaces".DHCPLease
	GetDHCPIndex() idxmap.NamedMapping

	// SetNotifyService allows to pass function for updating interface notifications.
	SetNotifyService(notify func(notification *vpp.Notification))
}

API defines methods exposed by VPP-IfPlugin.

type Config

type Config struct {
	MTU              uint32   `json:"mtu"`
	StatusPublishers []string `json:"status-publishers"`
}

Config defines configuration for VPP ifplugin.

func DefaultConfig

func DefaultConfig() Config

DefaultConfig returns Config with default values.

type Deps

type Deps struct {
	infra.PluginDeps
	KVScheduler kvs.KVScheduler
	GoVppmux    govppmux.StatsAPI
	AddrAlloc   netalloc.AddressAllocator

	/*	LinuxIfPlugin and NsPlugin deps are optional,
		but they are required if AFPacket or TAP+TAP_TO_VPP interfaces are used. */
	LinuxIfPlugin descriptor.LinuxPluginAPI
	NsPlugin      nsplugin.API

	// state publishing
	StatusCheck       statuscheck.PluginStatusWriter
	PublishErrors     datasync.KeyProtoValWriter            // TODO: to be used with a generic plugin for publishing errors (not just interfaces and BDs)
	Watcher           datasync.KeyValProtoWatcher           /* for resync of interface state data (PublishStatistics) */
	NotifyStates      datasync.KeyProtoValWriter            /* e.g. Kafka (up/down events only)*/
	PublishStatistics datasync.KeyProtoValWriter            /* e.g. ETCD (with resync) */
	DataSyncs         map[string]datasync.KeyProtoValWriter /* available DBs for PublishStatistics */
	PushNotification  func(notification *vpp.Notification)
}

Deps lists dependencies of the interface plugin.

type IfPlugin

type IfPlugin struct {
	Deps
	// contains filtered or unexported fields
}

IfPlugin configures VPP interfaces using GoVPP.

func NewPlugin

func NewPlugin(opts ...Option) *IfPlugin

NewPlugin creates a new Plugin with the provides Options

func (*IfPlugin) AfterInit

func (p *IfPlugin) AfterInit() error

AfterInit delegates the call to ifStateUpdater.

func (*IfPlugin) Close

func (p *IfPlugin) Close() error

Close stops all go routines.

func (*IfPlugin) GetDHCPIndex

func (p *IfPlugin) GetDHCPIndex() idxmap.NamedMapping

GetDHCPIndex gives read-only access to (untyped) map with DHCP leases. Cast metadata to "github.com/ligato/vpp-agent/api/models/vpp/interfaces".DHCPLease

func (*IfPlugin) GetInterfaceIndex

func (p *IfPlugin) GetInterfaceIndex() ifaceidx.IfaceMetadataIndex

GetInterfaceIndex gives read-only access to map with metadata of all configured VPP interfaces.

func (*IfPlugin) Init

func (p *IfPlugin) Init() (err error)

Init loads configuration file and registers interface-related descriptors.

func (*IfPlugin) SetNotifyService

func (p *IfPlugin) SetNotifyService(notify func(notification *vpp.Notification))

SetNotifyService sets notification callback for processing VPP notifications.

type InterfaceStateUpdater

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

InterfaceStateUpdater holds state data of all VPP interfaces.

func (*InterfaceStateUpdater) AfterInit

func (c *InterfaceStateUpdater) AfterInit() error

AfterInit subscribes for watching VPP notifications on previously initialized channel

func (*InterfaceStateUpdater) Close

func (c *InterfaceStateUpdater) Close() error

Close unsubscribes from interface state notifications from VPP & GOVPP channel

func (*InterfaceStateUpdater) Init

func (c *InterfaceStateUpdater) Init(ctx context.Context,
	logger logging.PluginLogger, kvScheduler kvs.KVScheduler,
	goVppMux govppmux.StatsAPI, swIfIndexes ifaceidx.IfaceMetadataIndex,
	publishIfState func(*intf.InterfaceNotification), readCounters bool,
) (err error)

Init members (channels, maps...) and start go routines

type Option

type Option func(*IfPlugin)

Option is a function that can be used in NewPlugin to customize Plugin.

func UseDeps

func UseDeps(f func(*Deps)) Option

UseDeps returns Option that can inject custom dependencies.
