Types

type AuditHistory

type AuditHistory struct {
	Score   float64              `json:"score"`
	Windows []AuditHistoryWindow `json:"windows"`
}

func GetAuditHistoryFromPB

func GetAuditHistoryFromPB(auditHistoryPB *pb.AuditHistory) AuditHistory

type AuditHistoryWindow

type AuditHistoryWindow struct {
	WindowStart time.Time `json:"windowStart"`
	TotalCount  int32     `json:"totalCount"`
	OnlineCount int32     `json:"onlineCount"`
}

type DB

type DB interface {
	// Store inserts or updates reputation stats into the DB
	Store(ctx context.Context, stats Stats) error
	// Get retrieves stats for specific satellite
	Get(ctx context.Context, satelliteID storj.NodeID) (*Stats, error)
	// All retrieves all stats from DB
	All(ctx context.Context) ([]Stats, error)
}

DB works with reputation database.

architecture: Database

type Metric

type Metric struct {
	TotalCount   int64 `json:"totalCount"`
	SuccessCount int64 `json:"successCount"`

	Alpha        float64 `json:"alpha"`
	Beta         float64 `json:"beta"`
	UnknownAlpha float64 `json:"unknownAlpha"`
	UnknownBeta  float64 `json:"unknownBeta"`
	Score        float64 `json:"score"`

func NewService

func NewService(log *zap.Logger, db DB, nodeID storj.NodeID, notifications *notifications.Service) *Service

NewService creates new instance of service.

func (*Service) Store

func (s *Service) Store(ctx context.Context, stats Stats, satelliteID storj.NodeID) error

Store stores reputation stats into db, and notify's in case of offline suspension.

type Stats

type Stats struct {
	SatelliteID storj.NodeID

	Audit       Metric
	OnlineScore float64

	DisqualifiedAt       *time.Time
	SuspendedAt          *time.Time
	OfflineSuspendedAt   *time.Time
	OfflineUnderReviewAt *time.Time
	VettedAt             *time.Time
	AuditHistory         *pb.AuditHistory
