Functions

func CounterAgg

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

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

func GaugeAgg

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

GaugeAgg returns a checkpointed gauge 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 counter.New() for counter instruments and gauge.New for gauge instruments.

func NewCounterRecord

func NewCounterRecord(desc *export.Descriptor, labels export.Labels, value int64) export.Record

Convenience method for building a test exported counter record.

func NewGaugeRecord

func NewGaugeRecord(desc *export.Descriptor, labels export.Labels, value int64) export.Record

Convenience method for building a test exported gauge record.

Types

type Encoder

type Encoder struct{}

Encoder is an alternate label encoder to validate grouping logic.

func (Encoder) Encode

func (Encoder) Encode(labels []core.KeyValue) string

type Output

type Output map[string]int64

Output collects distinct metric/label set outputs.

func (Output) AddTo

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

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