Functions ¶

func Counts ¶

func Counts(logical bool) (int, error)

Counts returns the number of physical or logical cores in the system

func CountsWithContext ¶

func CountsWithContext(ctx context.Context, logical bool) (int, error)

func Percent ¶

func Percent(interval time.Duration, percpu bool) ([]float64, error)

Percent calculates the percentage of cpu used either per CPU or combined. If an interval of 0 is given it will compare the current cpu times against the last call. Returns one value per cpu, or a single value if percpu is set to false.

func PercentWithContext ¶

func PercentWithContext(ctx context.Context, interval time.Duration, percpu bool) ([]float64, error)

}

TimesStat contains the amounts of time the CPU has spent performing different kinds of work. Time units are in seconds. It is based on linux /proc/stat file.

func Times ¶

func Times(percpu bool) ([]TimesStat, error)

func TimesWithContext ¶

func TimesWithContext(ctx context.Context, percpu bool) ([]TimesStat, error)

func (TimesStat) String ¶

func (c TimesStat) String() string

func (TimesStat) Total deprecated

func (c TimesStat) Total() float64

Deprecated: Total returns the total number of seconds in a CPUTimesStat Please do not use this internal function.
