Functions

func CalculateUtilizationOfResource

func CalculateUtilizationOfResource(nodeInfo *framework.NodeInfo, resourceName apiv1.ResourceName, skipDaemonSetPods, skipMirrorPods bool, currentTime time.Time) (float64, error)

CalculateUtilizationOfResource calculates utilization of a given resource for a node.

Types

type Info

type Info struct {
	CpuUtil float64
	MemUtil float64
	GpuUtil float64
	// Resource name of highest utilization resource
	ResourceName apiv1.ResourceName
	// Max(CpuUtil, MemUtil) or GpuUtils
	Utilization float64
}

Info contains utilization information for a node.

func Calculate

func Calculate(nodeInfo *framework.NodeInfo, skipDaemonSetPods, skipMirrorPods bool, gpuConfig *cloudprovider.GpuConfig, currentTime time.Time) (utilInfo Info, err error)

Calculate calculates utilization of a node, defined as maximum of (cpu, memory) or gpu utilization based on if the node has GPU or not. Per resource utilization is the sum of requests for it divided by allocatable. It also returns the individual cpu, memory and gpu utilization.
