Types

type Chan

type Chan struct {
	S chan os.Signal
}

func Exit

func Exit() *Chan

type Config

type Config struct {
	Stdin     io.Reader
	Stdout    io.Writer
	Stderr    io.Writer
	EnableStd bool `json:"enableStd" yaml:"enableStd" xml:"enableStd"`
	EnableEnv bool `json:"enableEnv" yaml:"enableEnv" xml:"enableEnv"`
}

type CpuInfo

type CpuInfo struct {
	User   float64 `json:"user"`
	System float64 `json:"system"`
	Idle   float64 `json:"idle"`
	Nice   float64 `json:"nice"`
}

func Cpu

func Cpu() CpuInfo

type DiskPath

type DiskPath struct {
	Path        string  `json:"path,omitempty"`
	Total       uint64  `json:"total"`
	Free        uint64  `json:"free"`
	Used        uint64  `json:"used"`
	UsedPercent float64 `json:"usedPercent"`
}

func Disk

func Disk() DiskPath

type Event

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

Event represents a one-time event that may occur in the future.

func NewEvent

func NewEvent() *Event

NewEvent returns a new, ready-to-use Event.

func (*Event) Done

func (e *Event) Done() <-chan struct{}

Done returns a channel that will be closed when Fire is called.

func (*Event) Fire

func (e *Event) Fire() bool

Fire causes e to complete. It is safe to call multiple times, and concurrently. It returns true iff this call to Fire caused the signaling channel returned by Done to close.

func (*Event) HasFired

func (e *Event) HasFired() bool

HasFired returns true if Fire has been called.

type ExecResult

type ExecResult struct {
	Command   string
	Result    string

}

func CmdRun

func CmdRun(cmd string, timeout int) ExecResult

func ShellRun

func ShellRun(cmd string) ExecResult

func (ExecResult) Error

func (r ExecResult) Error() string

type IPType

type IPType int8

func GetIPType

func GetIPType(IP net.IP) IPType

type MemInfo struct {
	// Total amount of RAM on this system
	Total uint64 `json:"total"`

	// RAM available for programs to allocate
	//
	// This value is computed from the kernel specific values.
	Available uint64 `json:"available"`

	// RAM used by programs
	//
	// This value is computed from the kernel specific values.
	Used uint64 `json:"used"`

	// Percentage of RAM used by programs
	//
	// This value is computed from the kernel specific values.
	UsedPercent float64 `json:"usedPercent"`
}

func Mem

func Mem() MemInfo
