uptime

Documentation

Overview

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

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

Functions

func Deserialize

func Deserialize(p []byte) u.Uptime

Deserialize takes some Flatbuffer serialized bytes and deserializes them as uptime.Uptime.

func Get

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

Get gets the current uptime, /proc/uptime, as Flatbuffer serialized bytes 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(up u.Uptime) (p []byte, err error)

Serialize serializes uptime information as Flatbuffers using the package's global Profiler.

Types

type Profiler

type Profiler struct {
	*u.Profiler
	*fb.Builder
}

Profiler processes the uptime information, /proc/uptime, using Flatbuffers.

func NewProfiler

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

Returns an initialized Profiler; ready to use.

func (*Profiler) Get

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

Get gets the current uptime, /proc/uptime, as Flatbuffer serialized bytes.

func (*Profiler) Serialize

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

Serialize serializes uptime information as Flatbuffers.

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.
