Types

type Process

type Process struct {
	// PID is the process ID.
	Pid string
	// Stat contains data from /proc/$pid/stat.
	Stat proc.Stat
	// Status contains data from /proc/$pid/status.
	Status proc.Status
	// CmdLine contains data from /proc/$pid/cmdline.
	CmdLine []string
	// Label containers data from /proc/$pid/attr/current.
	Label string
	// PidNS contains data from /proc/$pid/ns/pid.
	PidNS string
	// Huser is the effective host user of a container process.
	Huser string
	// Hgroup is the effective host group of a container process.
	Hgroup string
}

Process includes process-related from the /proc FS.

func FromPIDs

func FromPIDs(pids []string, joinUserNS bool) ([]*Process, error)

FromPIDs creates a new Process for each pid.

func New

func New(pid string, joinUserNS bool) (*Process, error)

New returns a new Process with the specified pid and parses the relevant data from /proc and /dev.

func (*Process) CPUTime

CPUTime returns the cumlative CPU time of process p as a time.Duration.

func (*Process) ElapsedTime

func (p *Process) ElapsedTime() (time.Duration, error)

ElapsedTime returns the time.Duration since process p was created.

func (*Process) SetHostData

func (p *Process) SetHostData() error

SetHostData sets all host-related data fields.

func (*Process) StartTime

func (p *Process) StartTime() (time.Time, error)

StartTime returns the time.Time when process p was started.
