	WriteTime        uint64 `json:"writeTime"`
	IopsInProgress   uint64 `json:"iopsInProgress"`
	IoTime           uint64 `json:"ioTime"`
	WeightedIO       uint64 `json:"weightedIO"`
	Name             string `json:"name"`
	SerialNumber     string `json:"serialNumber"`
	Label            string `json:"label"`
}

func (IOCountersStat) String 

func (d IOCountersStat) String() string

type PartitionStat 

type PartitionStat struct {
	Device     string `json:"device"`
	Mountpoint string `json:"mountpoint"`
	Fstype     string `json:"fstype"`
	Opts       string `json:"opts"`
}

func Partitions 

func Partitions(all bool) ([]PartitionStat, error)

Partitions returns disk partitions. If all is false, returns physical devices only (e.g. hard disks, cd-rom drives, USB keys) and ignore all others (e.g. memory partitions such as /dev/shm)

func PartitionsWithContext 

func PartitionsWithContext(ctx context.Context, all bool) ([]PartitionStat, error)

func (PartitionStat) String 

func (d PartitionStat) String() string

type UsageStat 

type UsageStat struct {
	Path              string  `json:"path"`
	Fstype            string  `json:"fstype"`
	Total             uint64  `json:"total"`
	Free              uint64  `json:"free"`
	Used              uint64  `json:"used"`
	UsedPercent       float64 `json:"usedPercent"`

	InodesUsedPercent float64 `json:"inodesUsedPercent"`
}

func Usage 

func Usage(path string) (*UsageStat, error)

Usage returns a file system usage. path is a filesystem path such as "/", not device file path like "/dev/vda1". If you want to use a return value of disk.Partitions, use "Mountpoint" not "Device".

func UsageWithContext 

func UsageWithContext(ctx context.Context, path string) (*UsageStat, error)

func (UsageStat) String 

func (d UsageStat) String() string
