Types ¶
type CPURegulator ¶
type CPURegulator struct {
types.ResourceEssentials
// contains filtered or unexported fields
}
CPURegulator gets raw cpu requirement data from policy and generates real cpu requirement for a certain region with fine-grained strategies to be robust
func (*CPURegulator) GetRequirement ¶ added in v0.4.0
func (c *CPURegulator) GetRequirement() int
GetRequirement returns the latest regulated cpu requirement
func (*CPURegulator) Regulate ¶
func (c *CPURegulator) Regulate(cpuRequirement float64)
Regulate runs an episode of cpu regulation to restrict raw cpu requirement and store the result as the latest cpu requirement value
func (*CPURegulator) SetEssentials ¶
func (c *CPURegulator) SetEssentials(essentials types.ResourceEssentials)
SetEssentials updates some essential parameters to restrict cpu requirement
func (*CPURegulator) SetLatestRequirement ¶ added in v0.4.0
func (c *CPURegulator) SetLatestRequirement(latestCPURequirement int)
SetLatestRequirement overwrites the latest regulated cpu requirement
type DummyRegulator ¶ added in v0.4.0
type DummyRegulator struct {
// contains filtered or unexported fields
}
DummyRegulator always get requirement without regulate
func (*DummyRegulator) GetRequirement ¶ added in v0.4.0
func (d *DummyRegulator) GetRequirement() int
func (*DummyRegulator) Regulate ¶ added in v0.4.0
func (d *DummyRegulator) Regulate(requirement float64)
func (*DummyRegulator) SetEssentials ¶ added in v0.4.0
func (d *DummyRegulator) SetEssentials(_ types.ResourceEssentials)
func (*DummyRegulator) SetLatestRequirement ¶ added in v0.4.0
func (d *DummyRegulator) SetLatestRequirement(latestRequirement int)
type Regulator ¶ added in v0.4.0
type Regulator interface {
// SetEssentials updates some essential parameters to restrict requirement
SetEssentials(essentials types.ResourceEssentials)
// SetLatestRequirement overwrites the latest regulated requirement
SetLatestRequirement(latestRequirement int)
// Regulate runs an episode of regulation to restrict raw requirement and store the result
// as the latest requirement value
Regulate(requirement float64)
// GetRequirement returns the latest regulated requirement
GetRequirement() int
}
Regulator gets raw requirement data from policy and generates real requirement for a certain region with fine-grained strategies to be robust
func NewCPURegulator ¶
func NewCPURegulator() Regulator
NewCPURegulator returns a cpu regulator instance with immutable parameters
func NewDummyRegulator ¶ added in v0.4.0
func NewDummyRegulator() Regulator
