Functions ¶

func NewDefaultConfig ¶

func NewDefaultConfig() *sdk.Config

NewDefaultConfig returns a new, default DDSketch config.

Types ¶

type Aggregator ¶

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

Aggregator aggregates measure events.

func New ¶

func New(cfg *sdk.Config, desc *export.Descriptor) *Aggregator

New returns a new DDSketch aggregator.

func (*Aggregator) Collect ¶

func (c *Aggregator) Collect(ctx context.Context, rec export.MetricRecord, exp export.MetricBatcher)

Collect checkpoints the current value (atomically) and exports it.

func (*Aggregator) Count ¶

func (c *Aggregator) Count() int64

Count returns the count of the checkpoint.

func (*Aggregator) Max ¶

func (c *Aggregator) Max() float64

Max returns the max of the checkpoint.

func (*Aggregator) Merge ¶

func (c *Aggregator) Merge(oa export.MetricAggregator, d *export.Descriptor)

func (*Aggregator) Min ¶

func (c *Aggregator) Min() float64

Min returns the min of the checkpoint.

func (*Aggregator) Quantile ¶

func (c *Aggregator) Quantile(q float64) float64

Quantile returns the estimated quantile of the checkpoint.

func (*Aggregator) Sum ¶

func (c *Aggregator) Sum() float64

Sum returns the sum of the checkpoint.

func (*Aggregator) Update ¶

func (c *Aggregator) Update(_ context.Context, number core.Number, rec export.MetricRecord)

Update modifies the current value (atomically) for later export.
