Overview

Package loadAvg gets loadavg information from the /proc/loadavg file. Instead of returning a Go struct, it returns JSON serialized bytes. A function to deserialize the JSON serialized bytes into an loadavg.LoadAvg struct is provided.

Note: the package name is loadavg and not the final element of the import path (json).

Functions

func Deserialize

func Deserialize(p []byte) (la l.LoadAvg, err error)

Deserialize takes some JSON serialized bytes and unmarshals them as loadavg.LoadAvg.

func Get

func Get() (p []byte, err error)

Get returns the current loadavg information as JSON serialized bytes using the package's global Profiler.

func Marshal

func Marshal(la l.LoadAvg) ([]byte, error)

Marshal is an alias for Serialize using the package's global profiler.

func NewTicker

func NewTicker(d time.Duration) (joe.Tocker, error)

NewTicker returns a new Ticker containing a Data channel that delivers the data at intervals and an error channel that delivers any errors encountered. Stop the ticker to signal the ticker to stop running. Stopping the ticker does not close the Data channel; call Close to close both the ticker and the data channel.

func Serialize

func Serialize(la l.LoadAvg) (p []byte, err error)

Serialize loadavg.LoadAvg using JSON with the package's global Profiler.

func Unmarshal

func Unmarshal(p []byte) (l.LoadAvg, error)

Unmarshal is an alias for Deserialize.

Types

type Profiler

type Profiler struct {
	*l.Profiler
}

Profiler is used to process the loadavg information, /proc/loadavg, using JSON.

func NewProfiler

func NewProfiler() (prof *Profiler, err error)

Returns an initialized Profiler; ready to use.

func (*Profiler) Get

func (prof *Profiler) Get() (p []byte, err error)

Get returns the current loadavg information as JSON serialized bytes.

func (*Profiler) Marshal

func (prof *Profiler) Marshal(la l.LoadAvg) ([]byte, error)

Marshal is an alias for Serialize.

func (*Profiler) Serialize

func (prof *Profiler) Serialize(la l.LoadAvg) ([]byte, error)

Serialize loadavg.LoadAvg using JSON.

type Ticker

type Ticker struct {
	*joe.Ticker
	Data chan []byte
	*Profiler
}

Ticker delivers the system's loadavg information at intervals.

func (*Ticker) Close

func (t *Ticker) Close()

Close closes the ticker resources.
