Types

type Prometheus

type Prometheus struct {
	ReverseProxy *httputil.ReverseProxy
	// contains filtered or unexported fields
}

func New

func New(baseLog *logrus.Entry,
	dbOpenShiftClusters database.OpenShiftClusters,
	dialer proxy.Dialer,
) *Prometheus

func (*Prometheus) Cli

func (p *Prometheus) Cli(ctx context.Context, resourceID string) (*http.Client, error)

func (*Prometheus) Director

func (p *Prometheus) Director(r *http.Request)

Director modifies the request to point to the clusters prometheus instance

func (*Prometheus) GetPrometheusHostAndScheme

func (p *Prometheus) GetPrometheusHostAndScheme() (string, string)

func (*Prometheus) ModifyResponse

func (p *Prometheus) ModifyResponse(r *http.Response) error

ModifyResponse: unfortunately Prometheus serves HTML files containing just a couple of absolute links. Given that we're serving Prometheus under /subscriptions/.../clusterName/prometheus, we need to dig these out and rewrite them. This is a hack which hopefully goes away once we forward all metrics to Kusto.

func (*Prometheus) RoundTripper

func (p *Prometheus) RoundTripper(r *http.Request) (*http.Response, error)
