func (*ExporterTest) FindOneMetric ¶

func (m *ExporterTest) FindOneMetric(
	allMetrics map[string]*dto.MetricFamily,
	name string,
	labels map[string]string,
) (*Metric, error)

FindOneMetric expects to find exactly one metric with the given name, resource name, resource namespace, and labels. If no such metric is found, or if more than one is found, an error is returned.

`resourceName` and `resourceNamespace` are the values of the `name` and `namespace` labels, respectively.

If labels is nil, only the name and namespace labels are checked.

Get fetches the metrics from the Prometheus endpoint and returns them as a map of metric families.

func (*Metric) LabelValue ¶

func (m *Metric) LabelValue(name string) string

LabelValue returns the value of the label with the given name. If no such label is found, an empty string is returned.
