Functions

func CreateExecutionTimeMetric

func CreateExecutionTimeMetric(namespace string, help string) *prometheus.HistogramVec

CreateExecutionTimeMetric prepares a new histogram labeled with execution step

func Register

func Register()

Types

type ExecutionTimer

type ExecutionTimer struct {
	// contains filtered or unexported fields
}

ExecutionTimer measures execution time of a computation, split into major steps usual usage pattern is: timer := NewExecutionTimer(...) ; compute ; timer.ObserveStep() ; ... ; timer.ObserveTotal()

func NewExecutionTimer

func NewExecutionTimer(histo *prometheus.HistogramVec) *ExecutionTimer

NewExecutionTimer provides a timer for admission latency; call ObserveXXX() on it to measure

func NewTimer

func NewTimer() *ExecutionTimer

NewExecutionTimer provides a timer for Updater's RunOnce execution

func (*ExecutionTimer) ObserveTotal

func (t *ExecutionTimer) ObserveTotal()

ObserveTotal measures the execution time from the creation of the ExecutionTimer
