Dataset is a ZFS dataset. A dataset could be a clone, filesystem, snapshot, or volume. The Type struct member can be used to determine a dataset's type.

The field definitions can be found in the ZFS manual: http://www.freebsd.org/cgi/man.cgi?zfs(8).

func Datasets 

func Datasets(filter string) ([]*Dataset, error)

Datasets returns a slice of ZFS datasets, regardless of type. A filter argument may be passed to select a dataset with the matching name, or empty string ("") may be used to select all datasets.

func Filesystems 

func Filesystems(filter string) ([]*Dataset, error)

Filesystems returns a slice of ZFS filesystems. A filter argument may be passed to select a filesystem with the matching name, or empty string ("") may be used to select all filesystems.

func GetDataset 

func GetDataset(name string) (*Dataset, error)

GetDataset retrieves a single ZFS dataset by name. This dataset could be any valid ZFS dataset type, such as a clone, filesystem, snapshot, or volume.

func Snapshots 

func Snapshots(filter string) ([]*Dataset, error)

Snapshots returns a slice of ZFS snapshots. A filter argument may be passed to select a snapshot with the matching name, or empty string ("") may be used to select all snapshots.

func Volumes 

func Volumes(filter string) ([]*Dataset, error)

Volumes returns a slice of ZFS volumes. A filter argument may be passed to select a volume with the matching name, or empty string ("") may be used to select all volumes.

func (*Dataset) Snapshots 

func (d *Dataset) Snapshots() ([]*Dataset, error)

Snapshots returns a slice of all ZFS snapshots of a given dataset.

type Error 

type Error struct {
	Err    error
	Debug  string
	Stderr string
}

Error is an error which is returned when the `zfs` or `zpool` shell commands return with a non-zero exit code.

func (Error) Error 

func (e Error) Error() string

Error returns the string representation of an Error.

type Zfsbeat 

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

Zfsbeat configuration.

func (*Zfsbeat) Run 

func (bt *Zfsbeat) Run(b *beat.Beat) error

Run starts zfsbeat.

func (*Zfsbeat) Stop 

func (bt *Zfsbeat) Stop()

Stop stops zfsbeat.

type Zpool 

type Zpool struct {
	Name                     string
	Size                     uint64
	Capacity                 uint64

Zpool is a ZFS zpool. A pool is a top-level structure in ZFS, and can contain many descendent datasets.

func GetZpool 

func GetZpool(name string) (*Zpool, error)

GetZpool retrieves a single ZFS zpool by name.

func ListZpools 

func ListZpools() ([]*Zpool, error)

ListZpools list all ZFS zpools accessible on the current system.
