Types

type Metric

type Metric struct {
	MetricCollector prometheus.Collector
	ID              string
	Name            string
	Description     string
	Type            string
	Args            []string
}

Metric is a definition for the name, description, type, ID, and prometheus.Collector type (i.e. CounterVec, HistogramVec, etc) of each metric

type Metrics

type Metrics struct {

	// Context string to use as a prometheus URL label
	URLLabelFromContext string
	// contains filtered or unexported fields
}

Metrics contains the metrics gathered by the instance and its path

func NewMetrics
