Types

type Chore

type Chore struct {
	Loop *sync2.Cycle

	Counter *Counter
	// contains filtered or unexported fields
}

Chore implements the metrics chore.

architecture: Chore

func NewChore

func NewChore(log *zap.Logger, config Config, loop *segmentloop.Service) *Chore

NewChore creates a new instance of the metrics chore.

func (*Chore) Close

func (chore *Chore) Close() error

Close closes metrics chore.

func (*Chore) Run

func (chore *Chore) Run(ctx context.Context) (err error)

Run starts the metrics chore.

type Config

type Config struct {
}

Config contains configurable values for metrics collection.

type Counter

type Counter struct {
	// number of objects that has at least one remote segment
	RemoteObjects int64
	// number of objects that has all inline segments
	InlineObjects int64
	// contains filtered or unexported fields
}

Counter implements the segment loop observer interface for data science metrics collection.

architecture: Observer

func NewCounter

func NewCounter() *Counter

NewCounter instantiates a new counter to be subscribed to the metainfo loop.

func (*Counter) InlineSegment

func (counter *Counter) InlineSegment(ctx context.Context, segment *segmentloop.Segment) (err error)

InlineSegment increments the count for inline objects.

func (*Counter) LoopStarted

func (counter *Counter) LoopStarted(context.Context, segmentloop.LoopInfo) (err error)

LoopStarted is called at each start of a loop.

func (*Counter) RemoteSegment

func (counter *Counter) RemoteSegment(ctx context.Context, segment *segmentloop.Segment) (err error)

RemoteSegment increments the count for objects with remote segments.
