Functions

func BindingSchedule

func BindingSchedule(scheduleType string, duration float64, err error)

BindingSchedule can record a scheduling attempt and the duration since `start`.

func CountSchedulerBindings

func CountSchedulerBindings(event string)

CountSchedulerBindings records the number of binding added to scheduling queues by event type.

func Register

func Register()

Register all metrics.

func RegisterMetrics

func RegisterMetrics(extraMetrics ...prometheus.Collector)

RegisterMetrics registers a list of metrics. This function is exported because it is intended to be used by out-of-tree plugins to register their custom metrics.

func ScheduleStep

func ScheduleStep(action string, startTime time.Time)

ScheduleStep can record each scheduling step duration.

func SinceInSeconds

func SinceInSeconds(start time.Time) float64

SinceInSeconds gets the time since the specified start in seconds.
