Types

type Profile

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

Profile keeps various load-related statistics for a worker

func New

func New() *Profile

NewProfile creates a new Profile instance

func (*Profile) BeginCall

func (p *Profile) BeginCall(proc string) StopWatch

BeginCall starts a stop watch, measuring the duration of a call. It returns the stop watch interface.

func (*Profile) BeginReply

func (p *Profile) BeginReply(proc string) StopWatch

BeginReply starts a stop watch, measuring the duration of an execution. It returns the stop watch interface.

func (*Profile) Stat

func (p *Profile) Stat() *WorkerStat

type Stat

type Stat struct {
	Type           string
	Begin          int64
	End            int64
	Abort          int64
	DurAvg         float64
	DurStdDev      float64
	AbortDurAvg    float64
	AbortDurStdDev float64
}

func (*Stat) String

func (s *Stat) String() string

type StopWatch

type StopWatch interface {
	Stop()
	Abort()
}

StopWatch represents a stop watch

func NewStopWatch

func NewStopWatch(stopFunc, abortFunc func(time.Duration)) StopWatch

type WorkerStat

type WorkerStat struct {
	ReplyTotal *Stat
	ReplyProc  map[string]*Stat
	CallTotal  *Stat
	CallProc   map[string]*Stat
}

func (*WorkerStat) String

func (s *WorkerStat) String() string
