Functions

func ExtractMetricTypeFromKind

func ExtractMetricTypeFromKind(kind string) (string, error)

func MetricsTypesForNsAndCluster

func MetricsTypesForNsAndCluster() map[string]string

Types

type CustomMetric

type CustomMetric struct {
	Type      string
	Namespace string
	Name      string
	Query     string
}

type MetricsQueriesState

type MetricsQueriesState struct {
	State map[string]map[string]interface{}
}

MetricsQueriesState Examples for full path namespaced

prometheusMetricsAdapter.internal.customMetrics.pod.name.namespaced.ns1

cluster

prometheusMetricsAdapter.internal.customMetrics.pod.name.cluster

in this state we have all keys after 'customMetrics' we collect all current metrics and replace 'customMetrics' 'customMetrics' is map which should have (metric type) 'pod, ingress... etc' keys in constructor we create it

func NewMetricsQueryValues

func NewMetricsQueryValues() *MetricsQueriesState

func (*MetricsQueriesState) AddMetric

func (s *MetricsQueriesState) AddMetric(m *CustomMetric)
