Types

type Config

type Config struct {
	Interval time.Duration `help:"how frequently bandwidth usage rollups are calculated" default:"1h0m0s"`
}

Config defines parameters for storage node Collector.

type DB

type DB interface {
	Add(ctx context.Context, satelliteID storj.NodeID, action pb.PieceAction, amount int64, created time.Time) error
	// MonthSummary returns summary of the current months bandwidth usages.
	MonthSummary(ctx context.Context, now time.Time) (int64, error)
	Rollup(ctx context.Context) (err error)
	// Summary returns summary of bandwidth usages.
	Summary(ctx context.Context, from, to time.Time) (*Usage, error)
	// EgressSummary returns summary of egress bandwidth usages.
	EgressSummary(ctx context.Context, from, to time.Time) (*Usage, error)
	// IngressSummary returns summary of ingress bandwidth usages.
	IngressSummary(ctx context.Context, from, to time.Time) (*Usage, error)
	// SatelliteSummary returns aggregated bandwidth usage for a particular satellite.
	SatelliteSummary(ctx context.Context, satelliteID storj.NodeID, from, to time.Time) (*Usage, error)
	// SatelliteEgressSummary returns egress bandwidth usage for a particular satellite.
	SatelliteEgressSummary(ctx context.Context, satelliteID storj.NodeID, from, to time.Time) (*Usage, error)
	// SatelliteIngressSummary returns ingress bandwidth usage for a particular satellite.
	SatelliteIngressSummary(ctx context.Context, satelliteID storj.NodeID, from, to time.Time) (*Usage, error)
	SummaryBySatellite(ctx context.Context, from, to time.Time) (map[storj.NodeID]*Usage, error)
	// GetDailyRollups returns slice of daily bandwidth usage rollups for provided time range,
	// sorted in ascending order.
	GetDailyRollups(ctx context.Context, from, to time.Time) ([]UsageRollup, error)
	// GetDailySatelliteRollups returns slice of daily bandwidth usage for provided time range,
	// sorted in ascending order for a particular satellite.
	GetDailySatelliteRollups(ctx context.Context, satelliteID storj.NodeID, from, to time.Time) ([]UsageRollup, error)
}

DB contains information about bandwidth usage.

architecture: Database

type Egress

type Egress struct {
	Repair int64 `json:"repair"`
	Audit  int64 `json:"audit"`
	Usage  int64 `json:"usage"`
}

Egress stores info about storage node egress usage.

type Ingress

type Ingress struct {
	Repair int64 `json:"repair"`
	Usage  int64 `json:"usage"`
}

Ingress stores info about storage node ingress usage.

type Service

type Service struct {
	Loop *sync2.Cycle
	// contains filtered or unexported fields
}

Service implements

architecture: Chore

func NewService

func NewService(log *zap.Logger, db DB, config Config) *Service

NewService creates a new bandwidth service.

func (*Service) Close

func (service *Service) Close() (err error)

Close stops the background process for rollups of bandwidth usage

func (*Service) Rollup

func (service *Service) Rollup(ctx context.Context) (err error)

Rollup calls bandwidth DB Rollup method and logs any errors

func (*Service) Run

func (service *Service) Run(ctx context.Context) (err error)

Run starts the background process for rollups of bandwidth usage

type Usage

type Usage struct {
	Invalid int64
	Unknown int64

	Put       int64
	Get       int64
	GetAudit  int64
	GetRepair int64
	PutRepair int64
	Delete    int64
}

Usage contains bandwidth usage information based on the type

func TotalMonthlySummary

func TotalMonthlySummary(ctx context.Context, db DB) (*Usage, error)

TotalMonthlySummary returns total bandwidth usage for current month

func (*Usage) Add

func (usage *Usage) Add(b *Usage)

Add adds another usage to this one.

func (*Usage) Include

func (usage *Usage) Include(action pb.PieceAction, amount int64)

Include adds specified action to the appropriate field.

func (*Usage) Total

func (usage *Usage) Total() int64

Total sums all type of bandwidths

type UsageRollup

type UsageRollup struct {
	Egress        Egress    `json:"egress"`
	Ingress       Ingress   `json:"ingress"`
	Delete        int64     `json:"delete"`
	IntervalStart time.Time `json:"intervalStart"`
}

UsageRollup contains rolluped bandwidth usage.
