type Counter ¶
Counter implements the counter metric with an expvar float. Label values are not supported.
type Counter struct {
// contains filtered or unexported fields
}
func NewCounter ¶
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 ¶
func (c *Counter) Add(delta float64)
Add implements Counter.
func (*Counter) With ¶
func (c *Counter) With(labelValues ...string) metrics.Counter
With is a no-op.
type Gauge ¶
Gauge implements the gauge metric with an expvar float. Label values are not supported.
type Gauge struct {
// contains filtered or unexported fields
}
func NewGauge ¶
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 ¶
func (g *Gauge) Add(delta float64)
Add implements metrics.Gauge.
func (*Gauge) Set ¶
func (g *Gauge) Set(value float64)
Set implements Gauge.
func (*Gauge) With ¶
func (g *Gauge) With(labelValues ...string) metrics.Gauge
With is a no-op.
type Histogram ¶
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.
type Histogram struct {
// contains filtered or unexported fields
}
func NewHistogram ¶
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 ¶
func (h *Histogram) Observe(value float64)
Observe implements Histogram.
func (*Histogram) With ¶
func (h *Histogram) With(labelValues ...string) metrics.Histogram
With is a no-op.
