Function NewGauge

prometheus/gauge.go:78–88

NewGauge creates a new Gauge based on the provided GaugeOpts. The returned implementation is optimized for a fast Set method. If you have a choice for managing the value of a Gauge via Set vs. Inc/Dec/Add/Sub, pick the former. For example, the Inc method of the returned Gauge is slower than the Inc

(opts GaugeOpts)

// scenarios for Gauges and Counters, where the former tends to be Set-heavy and
// the latter Inc-heavy.
func NewGauge(opts GaugeOpts) Gauge {
	desc := NewDesc(
		BuildFQName(opts.Namespace, opts.Subsystem, opts.Name),
		opts.Help,
		nil,
		opts.ConstLabels,
	)
	result := &gauge{desc: desc, labelPairs: desc.constLabelPairs}
	result.init(result) // Init self-collection.
	return result
}
