Functions

func CounterForLabels

func CounterForLabels(metricName string, labels map[string]string, metrics map[string]*dto.MetricFamily) (int, error)

CounterForLabels retrieves the value of the Counter matching the given set of labels.

func ForPod

func ForPod(source, target *corev1.Pod, namespace string) ([]map[string]*dto.MetricFamily, error)

MetricsForPod returns the parsed metrics for the given pod, scraping them from the source pod.

func GaugeForLabels

func GaugeForLabels(metricName string, labels map[string]string, metrics map[string]*dto.MetricFamily) (int, error)

GaugeForLabels retrieves the value of the Gauge matching the given set of labels.

func GreaterThan

func GreaterThan(min int) func(value int) error

func ValidateCounterValue

func ValidateCounterValue(check func(int) error, metricName string, labels map[string]string, allMetrics []map[string]*dto.MetricFamily) error

ValidateCounterValue checks that the value related to the given metric is at most the expectedMax value.

func ValidateGaugeValue

func ValidateGaugeValue(expectedValue int, metricName string, labels map[string]string, allMetrics []map[string]*dto.MetricFamily) error

ValidateGaugeValue checks that the value corresponing to the given metric is the same as expected value.
