Functions

func InternalCall 

func InternalCall(c stack.Call) bool

InternalCall returns true if the call is internal to the Go runtime.

func PkgDotName added in v1.1.1 

func PkgDotName(f stack.Func) string

PkgDotName returns a package-qualified function name.

func SameArgs 

func SameArgs(a stack.Args, b stack.Args) bool

SameArgs returns true only if both stack arguments are exactly equal.

Types

type Call 

type Call struct {
	StartDelta time.Duration
	EndDelta   time.Duration

	Samples int
	Args    stack.Args
	Name    string
	Package string
	// contains filtered or unexported fields
}

Call is an individual function call seen within a layer.

type GoroutineTimeline 

type GoroutineTimeline struct {
	ID        int
	Signature stack.Signature
	Layers    []*Layer
}

GoroutineTimeline represents a time series for an individual goroutine.

type Layer 

type Layer struct {
	Calls []*Call
}

Layer is a layer in a call stack.

type StackSample 

type StackSample struct {
	Time    time.Time
	Context *stack.Snapshot
}

StackSample represents a single Go stack at a point in time.

func Read 

func Read(r io.Reader) ([]*StackSample, error)

Read parses a stack log input.

type Timeline 

type Timeline struct {
	Start      time.Time
	End        time.Time
	Samples    int
	Goroutines map[int]*GoroutineTimeline
}

Timeline represents a time series of Goroutine stacks.

func CreateTimeline 

func CreateTimeline(samples []*StackSample, ignoreCreators []string, goroutines []int) *Timeline

CreateTimeline creates a timeline from stack samples.

func SimplifyTimeline 

func SimplifyTimeline(tl *Timeline) *Timeline

SimplifyTimeline flattens overlapping layers from call-stacks in a timeline.
