uptime

Documentation

Overview

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

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

Functions

func Deserialize

func Deserialize(p []byte) (up u.Uptime, err error)

Deserialize takes some JSON serialized bytes and unmarshals them as uptime.Uptime.

func Get

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

Get gets the current uptime, /proc/uptime, as JSON serialized bytes using the package's global Profiler.

func Marshal

func Marshal(up u.Uptime) ([]byte, error)

Marshal is an alias for Serialize that uses 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(up u.Uptime) (p []byte, err error)

Serialize uptime.Uptime as JSON using the package's global Profiler.

func Unmarshal

func Unmarshal(p []byte) (up u.Uptime, err error)

Unmarshal is an alias for Deserialize.

Types

type Profiler

type Profiler struct {
	*u.Profiler
}

Profiler processes uptime information, /proc/uptime, 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 gets the current uptime, /proc/uptime, as JSON serialized bytes.

func (*Profiler) Marshal

func (prof *Profiler) Marshal(up u.Uptime) ([]byte, error)

Marshal is an alias for Serialize.

func (*Profiler) Serialize

func (prof *Profiler) Serialize(up u.Uptime) ([]byte, error)

Serialize uptime.Uptime as JSON.

type Ticker

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

Ticker delivers the system's uptime at intervals.

func (*Ticker) Close

func (t *Ticker) Close()

Close closes the ticker resources.

func (*Ticker) Run

func (t *Ticker) Run()

Run runs the ticker.
