Functions ¶

func CounterAgg ¶

func CounterAgg(desc *metric.Descriptor, v int64) export.Aggregator

CounterAgg returns a checkpointed counter aggregator w/ the specified descriptor and value.

func LastValueAgg ¶ added in v0.3.0

func LastValueAgg(desc *metric.Descriptor, v int64) export.Aggregator

LastValueAgg returns a checkpointed lastValue aggregator w/ the specified descriptor and value.

func NewAggregationSelector ¶

func NewAggregationSelector() export.AggregationSelector

NewAggregationSelector returns a policy that is consistent with the test descriptors above. I.e., it returns sum.New() for counter instruments and lastvalue.New for lastValue instruments.

func NewCounterRecord ¶ added in v0.2.0

func NewCounterRecord(desc *metric.Descriptor, labels *label.Set, value int64) export.Record

Convenience method for building a test exported counter record.

func NewLastValueRecord ¶ added in v0.3.0

func NewLastValueRecord(desc *metric.Descriptor, labels *label.Set, value int64) export.Record

Convenience method for building a test exported lastValue record.

Types ¶

type Encoder ¶

type Encoder struct{}

Encoder is an alternate label encoder to validate grouping logic.

func (Encoder) Encode ¶

func (Encoder) Encode(iter label.Iterator) string

func (Encoder) ID ¶ added in v0.4.0

func (Encoder) ID() label.EncoderID

type Output ¶

type Output struct {
	Map map[string]float64
	// contains filtered or unexported fields
}

Output collects distinct metric/label set outputs.

func NewOutput ¶ added in v0.4.0

func NewOutput(labelEncoder label.Encoder) Output

func (Output) AddTo ¶

func (o Output) AddTo(rec export.Record) error

AddTo adds a name/label-encoding entry with the lastValue or counter value to the output map.
