metrics

type Counter ¶

type Counter struct {
	Name  string
	Tags  map[string]string
	Field string
	// contains filtered or unexported fields
}

Counter inherits metrics.Counter and provides counter in influxdb format. Use a counter to derive rates (e.g., record total number of requests, derive requests per second).

func NewCounter(name string, tags map[string]string, field string) *Counter

type Gauge ¶

type Gauge struct {
	Name  string
	Tags  map[string]string
	Field string
	// contains filtered or unexported fields
}

Gauge inherits metrics.Gauge and provides gauges in influxdb format. A Gauge is an instantaneous measurement of a value.

Use a gauge to track metrics which increase and decrease (e.g., amount of free memory).

func NewGauge(name string, tags map[string]string, field string) *Gauge

type Histogram ¶

type Histogram struct {
	*metrics.Histogram
}

A Histogram measures the distribution of a stream of values. Use a histogram to track the distribution of a stream of values (e.g., the latency associated with HTTP requests).

func NewHistogram(name string, tags map[string]string, field string, minValue, maxValue int64) *Histogram
