Types

type Gather

type Gather struct {
	MetricsClient                 metricsclient.MetricsClient

}

Gather (Resource) provides functionality for retrieving metrics for resource metric specs.

func (*Gather) GetMetric

func (c *Gather) GetMetric(resource corev1.ResourceName, namespace string, selector labels.Selector) (*Metric, error)

GetMetric retrieves a resource metric

func (*Gather) GetRawMetric

func (c *Gather) GetRawMetric(resource corev1.ResourceName, namespace string, selector labels.Selector) (*Metric, error)

GetRawMetric retrieves a a raw resource metric

type Gatherer

type Gatherer interface {
	GetMetric(resource corev1.ResourceName, namespace string, selector labels.Selector) (*Metric, error)
	GetRawMetric(resource corev1.ResourceName, namespace string, selector labels.Selector) (*Metric, error)
}

Gatherer (Resource) allows retrieval of resource metrics.

Metric (Resource) is a resource metric known to Kubernetes, as specified in requests and limits, describing each pod in the current scale target (e.g. CPU or memory). Such metrics are built in to Kubernetes, and have special scaling options on top of those available to normal per-pod metrics (the "pods" source).
