Functions

func DeleteMetricsForPod

func DeleteMetricsForPod(pod *corev1.Pod)

func EnableMetrics

func EnableMetrics(address string)

func GetPodQueue

func GetPodQueue() workqueue.DelayingInterface

func GetRegistry

func GetRegistry() *prometheus.Registry

func ListMetricsWithPod

func ListMetricsWithPod() []*prometheus.MetricVec

func NewCounterVecWithPod

func NewCounterVecWithPod(opts prometheus.CounterOpts, labels []string) *prometheus.CounterVec

NewCounterVecWithPod is a wrapper around prometheus.NewCounterVec that also registers the metric to be cleaned up when a pod is deleted. It should be used only to register metrics that have "pod" and "namespace" labels.

func NewGaugeVecWithPod

func NewGaugeVecWithPod(opts prometheus.GaugeOpts, labels []string) *prometheus.GaugeVec

NewGaugeVecWithPod is a wrapper around prometheus.NewGaugeVec that also registers the metric to be cleaned up when a pod is deleted. It should be used only to register metrics that have "pod" and "namespace" labels.

func NewHistogramVecWithPod

func NewHistogramVecWithPod(opts prometheus.HistogramOpts, labels []string) *prometheus.HistogramVec

NewHistogramVecWithPod is a wrapper around prometheus.NewHistogramVec that also registers the metric to be cleaned up when a pod is deleted. It should be used only to register metrics that have "pod" and "namespace" labels.

func RegisterPodDeleteHandler

func RegisterPodDeleteHandler()

RegisterPodDeleteHandler registers handler for deleting metrics associated with deleted pods. Without it, Tetragon kept exposing stale metrics for deleted pods. This was causing continuous increase in memory usage in Tetragon agent as well as in the metrics scraper.

func StartPodDeleteHandler

func StartPodDeleteHandler()
