Struct ExemplarV2

pkg/cortexpb/cortex.pb.go:424–438

Exemplar is an additional information attached to some series' samples. It is typically used to attach an example trace or request ID associated with the metric changes.

// It is typically used to attach an example trace or request ID associated with
// the metric changes.
type ExemplarV2 struct {
	// labels_refs is an optional list of label name-value pair references, encoded
	// as indices to the Request.symbols array. This list's len is always
	// a multiple of 2, and the underlying labels should be sorted lexicographically.
	// If the exemplar references a trace it should use the `trace_id` label name, as a best practice.
	LabelsRefs []uint32 `protobuf:"varint,1,rep,packed,name=labels_refs,json=labelsRefs,proto3" json:"labels_refs,omitempty"`
	// value represents an exact example value. This can be useful when the exemplar
	// is attached to a histogram, which only gives an estimated value through buckets.
	Value float64 `protobuf:"fixed64,2,opt,name=value,proto3" json:"value,omitempty"`
	// timestamp represents the timestamp of the exemplar in ms.
	//
	// For Go, see github.com/prometheus/prometheus/model/timestamp/timestamp.go
	// for conversion from/to time.Time to Prometheus timestamp.
	Timestamp int64 `protobuf:"varint,3,opt,name=timestamp,proto3" json:"timestamp,omitempty"`
