Types

type HeapsterMetricsClient

type HeapsterMetricsClient struct {
	// contains filtered or unexported fields
}

HeapsterMetricsClient is Heapster-based implementation of MetricsClient

func NewHeapsterMetricsClient

func NewHeapsterMetricsClient(client client.Interface, namespace, scheme, service, port string) *HeapsterMetricsClient

NewHeapsterMetricsClient returns a new instance of Heapster-based implementation of MetricsClient interface.

func (*HeapsterMetricsClient) GetCPUUtilization

func (h *HeapsterMetricsClient) GetCPUUtilization(namespace string, selector map[string]string) (*int, time.Time, error)

func (*HeapsterMetricsClient) GetResourceConsumptionAndRequest

func (h *HeapsterMetricsClient) GetResourceConsumptionAndRequest(resourceName api.ResourceName, namespace string, selector map[string]string) (consumption *ResourceConsumption, request *resource.Quantity, timestamp time.Time, err error)

type MetricsClient

type MetricsClient interface {
	// GetCPUUtilization returns the average utilization over all pods represented as a percent of requested CPU
	// (e.g. 70 means that an average pod uses 70% of the requested CPU)
	// and the time of generation of the oldest of utilization reports for pods.
	GetCPUUtilization(namespace string, selector map[string]string) (*int, time.Time, error)
}

MetricsClient is an interface for getting metrics for pods.

type ResourceConsumption

type ResourceConsumption struct {
	Resource api.ResourceName
	Quantity resource.Quantity
}

ResourceConsumption specifies consumption of a particular resource.
