package prometheus

import "github.com/go-kit/kit/metrics/prometheus"

Package prometheus provides Prometheus implementations for metrics. Individual metrics are mapped to their Prometheus counterparts, and (depending on the constructor used) may be automatically registered in the global Prometheus metrics registry.

Types ¶

type Counter ¶

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

Counter implements Counter, via a Prometheus CounterVec.

func NewCounter ¶

func NewCounter(cv *prometheus.CounterVec) *Counter

NewCounter wraps the CounterVec and returns a usable Counter object.

func NewCounterFrom ¶

func NewCounterFrom(opts prometheus.CounterOpts, labelNames []string) *Counter

NewCounterFrom constructs and registers a Prometheus CounterVec, and returns a usable Counter object.

func (*Counter) Add ¶

func (c *Counter) Add(delta float64)

Add implements Counter.

func (*Counter) With ¶

func (c *Counter) With(labelValues ...string) metrics.Counter

With implements Counter.

type Gauge ¶

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

Gauge implements Gauge, via a Prometheus GaugeVec.

func NewGauge ¶

func NewGauge(gv *prometheus.GaugeVec) *Gauge

NewGauge wraps the GaugeVec and returns a usable Gauge object.

func NewGaugeFrom ¶

func NewGaugeFrom(opts prometheus.GaugeOpts, labelNames []string) *Gauge

NewGaugeFrom constructs and registers a Prometheus GaugeVec, and returns a usable Gauge object.

func (*Gauge) Add ¶

func (g *Gauge) Add(delta float64)

Add is supported by Prometheus GaugeVecs.

func (*Gauge) Set ¶

func (g *Gauge) Set(value float64)

Set implements Gauge.

func (*Gauge) With ¶

func (g *Gauge) With(labelValues ...string) metrics.Gauge

With implements Gauge.

type Histogram ¶

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

Histogram implements Histogram via a Prometheus HistogramVec. The difference between a Histogram and a Summary is that Histograms require predefined quantile buckets, and can be statistically aggregated.

func NewHistogram ¶

func NewHistogram(hv *prometheus.HistogramVec) *Histogram

NewHistogram wraps the HistogramVec and returns a usable Histogram object.

func NewHistogramFrom ¶

func NewHistogramFrom(opts prometheus.HistogramOpts, labelNames []string) *Histogram

NewHistogramFrom constructs and registers a Prometheus HistogramVec, and returns a usable Histogram object.

func (*Histogram) Observe ¶

func (h *Histogram) Observe(value float64)

Observe implements Histogram.

func (*Histogram) With ¶

func (h *Histogram) With(labelValues ...string) metrics.Histogram

With implements Histogram.

type Summary ¶

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

Summary implements Histogram, via a Prometheus SummaryVec. The difference between a Summary and a Histogram is that Summaries don't require predefined quantile buckets, but cannot be statistically aggregated.

func NewSummary ¶

func NewSummary(sv *prometheus.SummaryVec) *Summary

NewSummary wraps the SummaryVec and returns a usable Summary object.

func NewSummaryFrom ¶

func NewSummaryFrom(opts prometheus.SummaryOpts, labelNames []string) *Summary

NewSummaryFrom constructs and registers a Prometheus SummaryVec, and returns a usable Summary object.

func (*Summary) Observe ¶

func (s *Summary) Observe(value float64)

Observe implements Histogram.

func (*Summary) With ¶

func (s *Summary) With(labelValues ...string) metrics.Histogram

With implements Histogram.
