cpux

Documentation

Overview

Package cpux provides information about a system's cpus, where X is the integer of each CPU on the system, e.g. cpu0, cpu1, etc. On linux systems this comes from the sysfs filesystem. Not all paths are available on all systems, e.g. /sys/devices/system/cpu/cpuX/cpufreq and its children may not exist on some systems. If the system doesn't have a particular path, the field's value will be the type's zero value. Instead of returning a Go struct, Flatbuffer serialized bytes are returned. A function to deserialize the Flatbuffer serialized bytes into a cpux.CPU struct is provided.

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

Functions

func Deserialize

func Deserialize(p []byte) *cpux.CPUs

Deserialize takes some Flatbuffer serialized bytes and deserializes them as cpux.CPUs.

func Get

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

Get returns the cpux information as Flatbuffer serialized bytes using the package's global profiler.

func Serialize

func Serialize(cpus *cpux.CPUs) (p []byte)

Serialize cpux.CPUs using the package global profiler.

Types

type Profiler

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

Profiler is used to process the cpux information as Flatbuffers serialized bytes.

func NewProfiler

func NewProfiler() *Profiler

Initializes and returns a cpux profiler.

func (*Profiler) Get

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

Get returns the cpux information as Flatbuffer serialized bytes.

func (*Profiler) Serialize

func (p *Profiler) Serialize(cpus *cpux.CPUs) []byte

Serialize serializes cpux.CPUs using Flatbuffers.

func (*Profiler) SerializeCPU

func (p *Profiler) SerializeCPU(cpu *cpux.CPU) fb.UOffsetT

SerializeCPU serializes a CPU using flatbuffers and returns the resulting UOffsetT.

func (*Profiler) SerializeCache

func (p *Profiler) SerializeCache(id, inf string) fb.UOffsetT

SerializeCache serializes a cache entry using flatbuffers and returns the resulting UOffsetT.
