Functions ¶
func K8sClusterMetricsManipulator ¶
K8sClusterMetricsManipulator adds 'clusterName' metric to the MetricSet 'ms', taking the value from 'clusterName' argument.
func K8sEntityMetricsManipulator ¶
K8sEntityMetricsManipulator adds 'displayName' metric to the MetricSet, taking values from entity.name
func K8sMetricSetTypeGuesser ¶
func K8sMetricSetTypeGuesser(_, groupLabel, _ string, _ definition.RawGroups) (string, error)
K8sMetricSetTypeGuesser is the metric set type guesser for k8s integrations.
func NewK8sPopulator ¶
NewK8sPopulator creates a Kubernetes aware populator.
func Subtract ¶
func Subtract(left definition.FetchFunc, right definition.FetchFunc) definition.FetchFunc
Subtract returns a new FetchFunc that subtracts 2 values. It expects that the values are float64
Types ¶
type MultipleErrs ¶
type MultipleErrs struct {
Errs []error
}
MultipleErrs represents a bunch of errs. Recoverable == true means that you can keep working with those errors. Recoverable == false means you must handle the errors or panic.
