}

A Label is a Name and Value pair that provides additional information about the metric. It is metadata for the metric. For example, Kubernetes pod metrics always have 'namespace' label that represents which namespace the pod belongs to.

func (l *Label) String() string

type Operator ¶

type Operator string

const (
	OperatorEqual         Operator = "="
	OperatorNotEqual      Operator = "!="
	OperatorRegexMatch    Operator = "=~"
	OperatorNotRegexMatch Operator = "!~"
	OperatorIn            Operator = "in"
)

type Options ¶

type Options map[string]interface{}

type QueryCondition ¶

type QueryCondition struct {
	Key      string
	Operator Operator
	Value    []string
}

type Sample ¶

type Sample struct {
	Value     float64
	Timestamp int64
}

func (s *Sample) String() string

type TimeSeries ¶

type TimeSeries struct {
	// A collection of Labels that are attached by monitoring system as metadata
	// for the metrics, which are known as dimensions.
	Labels []Label
	// A collection of Samples in chronological order.
	Samples []Sample
}

TimeSeries is a stream of samples that belong to a metric with a set of labels
