All the histogram based metrics have 1ms as size for the smallest bucket.
Functions ¶
func RegisterMetrics ¶
func RegisterMetrics(extraMetrics ...metrics.Registerable)
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 RequirementPredictable ¶
RequirementPredictable can record a successful predicting attempt and the duration since `start`.
func RequirementPredictingError ¶
RequirementPredictingError can record a predicting attempt that had an error and the duration since `start`.
func RequirementUnpredictable ¶
RequirementUnpredictable can record a predicting attempt for an unpredictable requirement and the duration since `start`.
func SinceInSeconds ¶
SinceInSeconds gets the time since the specified start in seconds.
