Types

type Meta

type Meta struct {
	VHost, Namespace string
}

Meta holds the vhost and namespace of a metric object

type Metrics

type Metrics struct {
	CacheHandlerOnUpdateSummary prometheus.Summary
	ResourceEventHandlerSummary *prometheus.SummaryVec
	// contains filtered or unexported fields
}

Metrics provide Prometheus metrics for the app

func NewMetrics

func NewMetrics(registry *prometheus.Registry) *Metrics

NewMetrics creates a new set of metrics and registers them with the supplied registry.

func (*Metrics) SetDAGLastRebuilt

func (m *Metrics) SetDAGLastRebuilt(ts time.Time)

SetDAGLastRebuilt records the last time the DAG was rebuilt.

func (*Metrics) SetHTTPProxyMetric

func (m *Metrics) SetHTTPProxyMetric(metrics RouteMetric)

SetHTTPProxyMetric sets metric values for a set of HTTPProxies

func (*Metrics) SetIngressRouteMetric

func (m *Metrics) SetIngressRouteMetric(metrics RouteMetric)

SetIngressRouteMetric sets metric values for a set of IngressRoutes

type RouteMetric

type RouteMetric struct {
	Total    map[Meta]int
	Valid    map[Meta]int
	Invalid  map[Meta]int
	Orphaned map[Meta]int
	Root     map[Meta]int
}

RouteMetric stores various metrics for IngressRoute objects

type Service

type Service struct {
	httpsvc.Service
	*prometheus.Registry
	Client *kubernetes.Clientset
}

Service serves various metric and health checking endpoints

func (*Service) Start

func (svc *Service) Start(stop <-chan struct{}) error

Start fulfills the g.Start contract. When stop is closed the http server will shutdown.
