Types

type Prometheus

type Prometheus struct {
	prometheus.Client
}

func NewPrometheus

func NewPrometheus() (*Prometheus, error)

func (*Prometheus) CanHandleSelector

func (p *Prometheus) CanHandleSelector(labels entities.Selector) bool

CanHandleSelector returns true only if both prometheus query/url are defined

func (*Prometheus) ComputeObjective

func (p *Prometheus) ComputeObjective(o *entities.Objective, from time.Time, to time.Time) (*entities.Indicator, error)

func (*Prometheus) ComputeSloFromPrometheusQuery

func (p *Prometheus) ComputeSloFromPrometheusQuery(query string, from time.Time, to time.Time) (float64, error)

func (*Prometheus) ResourceFromSelector

func (prom *Prometheus) ResourceFromSelector(labels entities.Selector) string

No resource identifier can be found, this is part of prom env vars as we are running queries to Prometheus api

func (*Prometheus) RunPrometheusQuery

func (p *Prometheus) RunPrometheusQuery(query string, from time.Time, to time.Time) (model.Value, error)

type PrometheusAPI

type PrometheusAPI interface {
	RunPrometheusQuery(query string, url string, from time.Time, to time.Time) (model.Value, error)
	ComputeSloFromPrometheusQuery(query string, url string, from time.Time, to time.Time) (float64, error)
}
