for _, g := range metrics.Gauges { name := invalidChars.ReplaceAllLiteralString(g.Name, "_") desc := prometheus.NewDesc(name, "Consul metric "+g.Name, nil, nil) ch <- prometheus.MustNewConstMetric( desc, prometheus.GaugeValue, float64(g.Value)) }

Processing of counters is similar, except that a _total suffix is added to the metric name:

for _, c := range metrics.Counters { name := invalidChars.ReplaceAllLiteralString(c.Name, "_") desc := prometheus.NewDesc(name+"_total", "Consul metric "+c.Name, nil, nil) ch <- prometheus.MustNewConstMetric( desc, prometheus.CounterValue, float64(s.Count)) }

The contents of metrics.Samples are more complicated. While the samples are a Prometheus summary, the Go client does not currently support those for MustNewConstMetric. Instead, you can emulate it using two counters. _seconds is appended to the metric name, and the sum is divided by a thousand to convert from milliseconds to seconds:
