type Counter Uses

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

Counter implements the counter metric with an expvar float. Label values are not supported.

func NewCounter Uses

func NewCounter(name string) *Counter

NewCounter creates an expvar Float with the given name, and returns an object that implements the Counter interface.

func (*Counter) Add Uses

func (c *Counter) Add(delta float64)

Add implements Counter.

func (*Counter) With Uses

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

With is a no-op.

type Gauge Uses

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

Gauge implements the gauge metric with an expvar float. Label values are not supported.

func NewGauge Uses

func NewGauge(name string) *Gauge

NewGauge creates an expvar Float with the given name, and returns an object that implements the Gauge interface.

func (*Gauge) Add Uses

func (g *Gauge) Add(delta float64)

Add implements metrics.Gauge.

func (*Gauge) Set Uses

func (g *Gauge) Set(value float64)

Set implements Gauge.

func (*Gauge) With Uses

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

With is a no-op.

type Histogram Uses

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

Histogram implements the histogram metric with a combination of the generic Histogram object and several expvar Floats, one for each of the 50th, 90th, 95th, and 99th quantiles of observed values, with the quantile attached to the name as a suffix. Label values are not supported.

func NewHistogram Uses

func NewHistogram(name string, buckets int) *Histogram

NewHistogram returns a Histogram object with the given name and number of buckets in the underlying histogram object. 50 is a good default number of buckets.

func (*Histogram) Observe Uses

func (h *Histogram) Observe(value float64)

Observe implements Histogram.

func (*Histogram) With Uses

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

With is a no-op.
