Function NewConstSummary

prometheus/summary.go:752–772

NewConstSummary returns a metric representing a Prometheus summary with fixed values for the count, sum, and quantiles. As those parameters cannot be changed, the returned value does not implement the Summary interface (but only the Metric interface). Users of this package will not have much use for

(
	desc *Desc,
	count uint64,
	sum float64,
	quantiles map[float64]float64,
	labelValues ...string,
)

// NewConstSummary returns an error if the length of labelValues is not
// consistent with the variable labels in Desc or if Desc is invalid.
func NewConstSummary(
	desc *Desc,
	count uint64,
	sum float64,
	quantiles map[float64]float64,
	labelValues ...string,
) (Metric, error) {
	if desc.err != nil {
		return nil, desc.err
	}
	if err := validateLabelValues(labelValues, len(desc.variableLabels.names)); err != nil {
		return nil, err
	}
	return &constSummary{
		desc:       desc,
		count:      count,
		sum:        sum,
		quantiles:  quantiles,
		labelPairs: MakeLabelPairs(desc, labelValues),
	}, nil
}

// MustNewConstSummary is a version of NewConstSummary that panics where
// NewConstMetric would have returned an error.
