    Types

    type Counter

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

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

      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

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

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

              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

                      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

                        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.
