Functions

func Run

func Run(f Flags)

Run invokes processing.

Types

type Flags

type Flags struct {
	URL           string
	Iterations    int
	Delay         time.Duration
	NoGroup       bool
	SortTrace     bool
	KeepTemporary bool
	MinCount      int
	TruncateTrace int
	ShowFiltered  bool
}

Flags control Processor behavior.

func (*Flags) Register

func (f *Flags) Register()

Register adds flags.

type Processor

type Processor struct {
	Result map[string]goroutine

	NoGroup       bool
	TraceGroups   map[string]int
	Output        []goroutine
	Persistent    int
	Temporary     int
	KeepTemporary bool

	Writer io.Writer
	// contains filtered or unexported fields
}

Processor groups goroutine stack traces.

func NewProcessor

func NewProcessor() *Processor

NewProcessor creates Processor.

func (*Processor) Count

func (p *Processor) Count()

Count counts persistent goroutines.

func (*Processor) Fetch

func (p *Processor) Fetch(n int, url string, delay time.Duration)

Fetch downloads multiple goroutine dumps by URL.

func (*Processor) Internal

func (p *Processor) Internal()

Internal dumps goroutines of current process.

func (*Processor) Load

func (p *Processor) Load(fn string)

Load adds goroutines dump from file.

func (*Processor) PrepareOutput

func (p *Processor) PrepareOutput(sortTrace bool)

PrepareOutput filters and orders traces.

func (*Processor) PrintResult

func (p *Processor) PrintResult(minCount int)

PrintResult prints grouped traces.

func (*Processor) Report

func (p *Processor) Report(f Flags)

Report processes and prints currently collected dumps.
