Types ¶

type Aggregator ¶

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

Aggregator aggregates gauge events.

func New ¶

func New() *Aggregator

New returns a new gauge aggregator. This aggregator retains the last value and timestamp that were recorded.

func (*Aggregator) AsNumber ¶

func (g *Aggregator) AsNumber() core.Number

AsNumber returns the recorded gauge value as an int64.

func (*Aggregator) Collect ¶

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

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

func (*Aggregator) Merge ¶

func (g *Aggregator) Merge(oa export.MetricAggregator, desc *export.Descriptor)

func (*Aggregator) Timestamp ¶

func (g *Aggregator) Timestamp() time.Time

Timestamp returns the timestamp of the alst recorded gauge value.

func (*Aggregator) Update ¶

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