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) Inc

func (c *Counter) Inc()

Inc increments the counter by 1.

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) Dec

func (g *Gauge) Dec()

func (*Gauge) Inc

func (g *Gauge) Inc()

func (*Gauge) Set

func (g *Gauge) Set(value float64)

Set implements Gauge.

func (*Gauge) SetToCurrentTime

func (g *Gauge) SetToCurrentTime()

func (*Gauge) Sub

func (g *Gauge) Sub(f float64)

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.
