Functions ¶
func EstimateContainerCPUUsage ¶
func EstimateContainerCPUUsage(ci *types.ContainerInfo, metaReader metacache.MetaReader, reclaimEnable bool) (float64, error)
EstimateContainerCPUUsage estimates non-reclaimed container cpu usage. Use cpu request if metrics are missing or reclaimEnable is false.
func EstimateContainerMemoryUsage ¶
func EstimateContainerMemoryUsage(ci *types.ContainerInfo, metaReader metacache.MetaReader, reclaimEnable bool) (float64, error)
EstimateContainerMemoryUsage estimates non-reclaimed container memory usage. Use memory request if metrics are missing or reclaimEnable is false.
func EstimateUtilBasedCapacity ¶ added in v0.3.0
func EstimateUtilBasedCapacity(options UtilBasedCapacityOptions, resourceSupply, currentUtilization, lastCapacityResult float64) (float64, error)
EstimateUtilBasedCapacity capacity by taking into account the difference between the current and target resource utilization of the workload pool
func GetAvailableNUMAsAndReclaimedCores ¶ added in v0.4.0
func GetAvailableNUMAsAndReclaimedCores(conf *config.Configuration, metaReader metacache.MetaReader, metaServer *metaserver.MetaServer) (machine.CPUSet, []*types.ContainerInfo, error)
func PodEnableReclaim ¶
func PodEnableReclaim(ctx context.Context, metaServer *metaserver.MetaServer, podUID string, nodeEnableReclaim bool) (bool, error)
PodEnableReclaim checks whether the pod can be reclaimed, if node does not enable reclaim, it will return false directly, if node enable reclaim, it will check whether the pod is degraded or baseline.
func PodPerformanceScore ¶ added in v0.3.0
func PodPerformanceScore(ctx context.Context, metaServer *metaserver.MetaServer, podUID string) (float64, error)
Types ¶
type PIDController ¶ added in v0.3.0
type PIDController struct {
// contains filtered or unexported fields
}
func NewPIDController ¶ added in v0.3.0
func NewPIDController(variableName string, params types.FirstOrderPIDParams) *PIDController
func (*PIDController) Adjust ¶ added in v0.3.0
func (c *PIDController) Adjust(controlKnob, target, current float64) float64
func (*PIDController) SetEssentials ¶ added in v0.3.0
func (c *PIDController) SetEssentials(resourceEssentials types.ResourceEssentials)
