Types

type MetricSink

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

A simple in-memory storage for metrics. It divides metrics into 2 categories * metrics that need to be stored for couple minutes. * metrics that need to be stored for longer time (15 min, 1 hour). The user of this struct needs to decide what are the long-stored metrics upfront.

func NewMetricSink
