}

type Counters

type Counters struct {
	Cfg *CounterConfig
	// contains filtered or unexported fields
}

Counters is a vec tor of counters for a each log stream.

func NewCounters

func NewCounters(name, help string, config interface{}) (*Counters, error)

func (Counters) Collect

func (c Counters) Collect(ch chan<- prometheus.Metric)

Collect implements prometheus.Collector

func (Counters) Describe

func (c Counters) Describe(ch chan<- *prometheus.Desc)
