Functions ¶

func Counts ¶

func Counts(logical bool) (int, error)

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)

Types ¶

type InfoStat ¶

type InfoStat struct {
	CPU        int32    `json:"cpu"`
	VendorID   string   `json:"vendorId"`
	Family     string   `json:"family"`
	Model      string   `json:"model"`
	Stepping   int32    `json:"stepping"`
	PhysicalID string   `json:"physicalId"`
	CoreID     string   `json:"coreId"`
	Cores      int32    `json:"cores"`
	ModelName  string   `json:"modelName"`
	Mhz        float64  `json:"mhz"`
	CacheSize  int32    `json:"cacheSize"`
	Flags      []string `json:"flags"`
	Microcode  string   `json:"microcode"`
}

func Info ¶

func Info() ([]InfoStat, error)

Returns only one CPUInfoStat on FreeBSD

func InfoWithContext ¶

func InfoWithContext(ctx context.Context) ([]InfoStat, error)

func (InfoStat) String ¶

func (c InfoStat) String() string

type TimesStat ¶

type TimesStat struct {
	CPU       string  `json:"cpu"`
	User      float64 `json:"user"`
	System    float64 `json:"system"`
	Idle      float64 `json:"idle"`
	Nice      float64 `json:"nice"`
	Iowait    float64 `json:"iowait"`
	Irq       float64 `json:"irq"`
	Softirq   float64 `json:"softirq"`
	Steal     float64 `json:"steal"`
	Guest     float64 `json:"guest"`
	GuestNice float64 `json:"guestNice"`
	Stolen    float64 `json:"stolen"`
}

TimesStat contains the amounts of time the CPU has spent performing different kinds of work. Time units are in USER_HZ or Jiffies (typically hundredths of a second). 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 ¶

func (c TimesStat) Total() float64

Total returns the total number of seconds in a CPUTimesStat
