const Namespace = "cilium_operator"

Namespace is the namespace key to use for cilium operator metrics.

Functions

func DumpMetrics

func DumpMetrics() ([]*models.Metric, error)

DumpMetrics gets the current Cilium operator metrics and dumps all into a Metrics structure. If metrics cannot be retrieved, returns an error.

func Register

func Register()

Register registers metrics for cilium-operator.

func Unregister

func Unregister()

Unregister shuts down the metrics server.
