Struct Sample

model/value.go:34–39

Sample is a sample pair associated with a metric. A single sample must either define Value or Histogram but not both. Histogram == nil implies the Value field is used, otherwise it should be ignored.

// define Value or Histogram but not both. Histogram == nil implies the Value
// field is used, otherwise it should be ignored.
type Sample struct {
	Metric    Metric           `json:"metric"`
	Value     SampleValue      `json:"value"`
	Timestamp Time             `json:"timestamp"`
	Histogram *SampleHistogram `json:"histogram"`
}

// Equal compares first the metrics, then the timestamp, then the value. The
// semantics of value equality is defined by SampleValue.Equal.
