Functions

func AllowPrometheusSync

func AllowPrometheusSync(logf logging.FormatLogger)

AllowPrometheusSync sleeps for sometime to allow prometheus time to scrape the metrics.

func PromAPI

func PromAPI() (v1.API, error)

PromAPI gets a handle to the prometheus API

func RunQuery

func RunQuery(ctx context.Context, logf logging.FormatLogger, promAPI v1.API, query string) (float64, error)

RunQuery runs a prometheus query and returns the metric value

func RunQueryRange

func RunQueryRange(ctx context.Context, logf logging.FormatLogger, promAPI v1.API, query string, r v1.Range) (float64, error)

RunQueryRange runs a prometheus query over the given range

func VectorValue

func VectorValue(val model.Value) (float64, error)

VectorValue gets the vector value from the value type

Types

type PromProxy

type PromProxy struct {
	Namespace string
	// contains filtered or unexported fields
}

PromProxy defines a proxy to the prometheus server

func (*PromProxy) Setup

func (p *PromProxy) Setup(ctx context.Context, kubeClientset kubernetes.Interface, logf logging.FormatLogger)

Setup performs a port forwarding for app prometheus-test in given namespace

func (*PromProxy) Teardown

func (p *PromProxy) Teardown(logf logging.FormatLogger)

Teardown will kill the port forwarding process if running.
