Functions

func GetHandler

func GetHandler() http.Handler

Types

type Instrumenter

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

func NewInstrumenter

func NewInstrumenter(subsystemIdentifier string) *Instrumenter

New creates a new Instrumenter. The subsystemIdentifier will be used as part of the metric names (e.g. http_<identifier>_requests_total).

func (*Instrumenter) InstrumentedRoundTripper

func (i *Instrumenter) InstrumentedRoundTripper() http.RoundTripper

InstrumentedRoundTripper returns an instrumented round tripper.

func (*Instrumenter) WithInsecureSkipVerify

func (i *Instrumenter) WithInsecureSkipVerify(insecure bool) *Instrumenter

func (*Instrumenter) WithProxy

func (i *Instrumenter) WithProxy(proxyURL string) *Instrumenter

type KubernetesMetricsLatency

type KubernetesMetricsLatency struct {
	Cluster string
}

func (*KubernetesMetricsLatency) Observe

func (r *KubernetesMetricsLatency) Observe(_ context.Context, _ string, u url.URL, latency time.Duration)

type KubernetesMetricsResult

type KubernetesMetricsResult struct {
	Cluster string
}

func (*KubernetesMetricsResult) Increment

func (r *KubernetesMetricsResult) Increment(_ context.Context, code string, _ string, host string)
