Types

type Prometheus

type Prometheus struct {
	// contains filtered or unexported fields
}

func NewPrometheus

func NewPrometheus(address string) (p *Prometheus, err error)

func (*Prometheus) PreciseQuery

func (p *Prometheus) PreciseQuery(query string, start time.Time, end time.Time) (val model.Value, err error)

func (*Prometheus) Query

func (p *Prometheus) Query(query string, start time.Time, end time.Time, step time.Duration) (model.Value, error)

type Source

type Source interface {

	// A data source may not implemented this method
	Query(query string, start time.Time, end time.Time, step time.Duration) (model.Value, error)

	// A data source must implemented this method
	//   for a non-prometheus data source, it could consider the 'query' as 'name'
	PreciseQuery(query string, start time.Time, end time.Time) (model.Value, error)
}

We support data source types other than prometheus,

but thay need to convert into prometheus-format
