Functions

func CpuTotalTicks

func CpuTotalTicks() uint64

CpuTotalTicks calculates the total MHz available across all cores.

Where asymetric cores are correctly detected, the total ticks is the sum of the performance across both core types.

Where asymetric cores are not correctly detected (such as Intel 13th gen), the total ticks available is over-estimated, as we assume all cores are P cores.

func RuntimeStats

func RuntimeStats() map[string]string

RuntimeStats is used to return various runtime information

func SetCpuTotalTicks

func SetCpuTotalTicks(newCpuTotalTicks uint64)

Set the total ticks available across all cores.

Types

type CpuStats

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

CpuStats calculates cpu usage percentage

func NewCpuStats

func NewCpuStats() *CpuStats

NewCpuStats returns a cpu stats calculator

func (*CpuStats) Percent

func (c *CpuStats) Percent(cpuTime float64) float64

Percent calculates the cpu usage percentage based on the current cpu usage and the previous cpu usage where usage is given as time in nanoseconds spend in the cpu

func (*CpuStats) TicksConsumed

func (c *CpuStats) TicksConsumed(percent float64) float64

TicksConsumed calculates the total ticks consumes by the process across all cpu cores
