Functions

func GetWatcherDeletedPodCacheHits

func GetWatcherDeletedPodCacheHits() prometheus.Counter

func GetWatcherErrors

func GetWatcherErrors(watcherType Watcher, watcherError ErrorType) prometheus.Counter

Get a new handle on an WatcherEvents metric for a watcher type

func GetWatcherEvents

func GetWatcherEvents(watcherType Watcher) prometheus.Counter

Get a new handle on an WatcherEvents metric for a watcher type

func InitMetrics

Types

type ErrorType

type ErrorType string

const (
	FailedToGetPodError ErrorType = "failed_to_get_pod"
)

type Watcher

type Watcher int

const (
	K8sWatcher Watcher = iota
)

TODO: Having only one watcher type, "k8s", makes it not a useful label. Maybe "pod" would be more informative.

func (Watcher) String

func (w Watcher) String() string
