type Factory ¶

type Factory struct {

Factory implements metrics.Factory backed by Prometheus registry.

func New ¶

func New(opts ...Option) *Factory

New creates a Factory backed by Prometheus registry. Typically the first argument should be prometheus.DefaultRegisterer.

Parameter buckets defines the buckets into which Timer observations are counted. Each element in the slice is the upper inclusive bound of a bucket. The values must be sorted in strictly increasing order. There is no need to add a highest bucket with +Inf bound, it will be added implicitly. The default value is prometheus.DefBuckets.

Counter implements Counter of metrics.Factory.

func (*Factory) Gauge ¶

func (f *Factory) Gauge(options metrics.Options) metrics.Gauge

Gauge implements Gauge of metrics.Factory.

func (*Factory) Histogram ¶

func (f *Factory) Histogram(options metrics.HistogramOptions) metrics.Histogram

Histogram implements Histogram of metrics.Factory.

func (*Factory) Namespace ¶
