Types

type Dimension

type Dimension map[KV]int64

Dimension defines a generic dimension.

type Int64Metrics

type Int64Metrics map[Key]Dimension

Int64Metrics defines a metric to dimension mapping for int64 metrics.

func GatherInt64Metric

func GatherInt64Metric(ms []metricdata.Metrics) Int64Metrics

GatherInt64Metric gathers the observed int64 metrics grouped by dimension.

type KV

type KV struct{ K, V string }

KV holds the key and value for a dimension

type Key

type Key struct{ Name, Unit string }

Key holds the key for the metric name and unit.

type TestMetric

type TestMetric struct {
	Reader        sdkmetric.Reader
	MeterProvider *sdkmetric.MeterProvider
	Meter         metric.Meter
}

TestMetric returns all the necessary for tests.

func New

func New() (tm TestMetric)

New creates a manual reader, meter provider and a meter from it.

func (TestMetric) Collect

func (tm TestMetric) Collect(ctx context.Context) (
	rm metricdata.ResourceMetrics, err error,
)

Collect returns the metrics from the reader.
