// if be CPU RealLimit/allocatedLimit > CPUEvictBESatisfactionUpperPercent, then stop evict bepods
CPUEvictBESatisfactionUpperPercent *int64 `json:"cpuEvictBESatisfactionUpperPercent,omitempty"`

// if be CPU (RealLimit/allocatedLimit < CPUEvictBESatisfactionLowerPercent and usage nearly 100%) continue CPUEvictTimeWindowSeconds,then start evict
CPUEvictBESatisfactionLowerPercent *int64 `json:"cpuEvictBESatisfactionUpperPercent,omitempty"`

// cpu evict start after continue avg(cpuusage) > CPUEvictThresholdPercent in seconds
