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(controller, 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 GreaterOrEqualThan

func GreaterOrEqualThan(min int) func(value int) error

func PrometheusPod

func PrometheusPod(cs clientset.Interface, namespace string) (*corev1.Pod, error)

PrometheusPod returns a prometheus pod.

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 corresponding to the given metric is the same as expected value.

func ValidateGaugeValueCompare

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

ValidateGaugeValueCompare checks that the value corresponding to the given metric against the given compare function.

func ValidateOnPrometheus

func ValidateOnPrometheus(prometheusPod *corev1.Pod, query string, expected CheckType) error

ValidateOnPrometheus checks the existence of the given metric directly on prometheus pods.
