Types

type CPU added in v0.6.1 

type CPU struct {
	List []CPUData
}

CPU type has a list of CPUData.

	N string
	// Pcts without "%"
	UserPct uint
	SysPct  uint
	WaitPct uint
	IdlePct uint
}

CPUData type is a struct of cpu metrics.

type CPUUpdater added in v0.6.1 

type CPUUpdater interface {
	UpdateCPU(sigar.Cpu, int64)
}

type DF added in v0.6.1 

type DF struct {
	List []DFData
}

DF type has a list of DFData.

type DFData added in v0.6.1 

type DFData struct {

	// inodes
	Inodes  string
	Iused   string
	Ifree   string

type ExtraMetricCPU
