Functions¶
funcBuildProfile¶
func BuildProfile(prof []ProfileRecord) *profile.Profile
funcMMUHandlerFunc¶
func MMUHandlerFunc(ranges []Range, fMutatorUtilFunc)http.HandlerFunc
funcMainHandler¶
funcSVGProfileHandlerFunc¶
func SVGProfileHandlerFunc(fProfileFunc)http.HandlerFunc
SVGProfileHandlerFunc serves pprof-like profile generated by prof as svg.
funcStaticHandler¶
funcTraceHandler¶
Types¶
typeArrowEvent¶
typeAsyncSliceEvent¶
type AsyncSliceEvent struct {SliceEventCategorystringScopestringTaskColorIndexuint64// Take on the same color as the task with this ID.}typeEmitter¶
type Emitter struct {// contains filtered or unexported fields}funcNewEmitter¶
func NewEmitter(cTraceConsumer, rangeStart, rangeEndtime.Duration) *Emitter
NewEmitter returns a new Emitter that writes to c. The rangeStart andrangeEnd args are used for splitting large traces.
func (*Emitter)Arrow¶
func (e *Emitter) Arrow(aArrowEvent)
func (*Emitter)AsyncSlice¶
func (e *Emitter) AsyncSlice(sAsyncSliceEvent)
func (*Emitter)Gomaxprocs¶
func (*Emitter)GoroutineTransition¶
func (*Emitter)IncThreadStateCount¶
func (e *Emitter) IncThreadStateCount(tstime.Duration, stateThreadState, deltaint64)
func (*Emitter)Instant¶
func (e *Emitter) Instant(iInstantEvent)
func (*Emitter)OptionalEvent¶
OptionalEvent emits ev if it's within the time range of the consumer, i.e.the selected trace split range.
func (*Emitter)SetResourceFilter¶
func (*Emitter)SetResourceType¶
func (*Emitter)Slice¶
func (e *Emitter) Slice(sSliceEvent)
func (*Emitter)Stack¶
func (e *Emitter) Stack(stk []trace.StackFrame)int
Stack emits the given frames and returns a unique id for the stack. Nopointers to the given data are being retained beyond the call to Stack.
func (*Emitter)TaskArrow¶
func (e *Emitter) TaskArrow(aArrowEvent)
func (*Emitter)TaskSlice¶
func (e *Emitter) TaskSlice(sSliceEvent)
typeInstantEvent¶
typeMutatorUtilFunc¶
type MutatorUtilFunc func(trace.UtilFlags) ([][]trace.MutatorUtil,error)
typeProfileFunc¶
type ProfileFunc func(r *http.Request) ([]ProfileRecord,error)
typeProfileRecord¶
type ProfileRecord struct {Stack []trace.StackFrameCountuint64Timetime.Duration}typeSliceEvent¶
typeThreadState¶
type ThreadStateint
const (ThreadStateInSyscallThreadState =iotaThreadStateInSyscallRuntimeThreadStateRunning)
typeTimeHistogram¶
TimeHistogram is an high-dynamic-range histogram for durations.
func (*TimeHistogram)Add¶
func (h *TimeHistogram) Add(dtime.Duration)
Add adds a single sample to the histogram.
typeTraceConsumer¶
type TraceConsumer struct {ConsumeTimeUnit func(unitstring)ConsumeViewerEvent func(v *format.Event, requiredbool)ConsumeViewerFrame func(keystring, fformat.Frame)Flush func()}funcSplittingTraceConsumer¶
func SplittingTraceConsumer(maxint) (*splitter,TraceConsumer)
funcViewerDataTraceConsumer¶
func ViewerDataTraceConsumer(wio.Writer, startIdx, endIdxint64)TraceConsumer
ViewerDataTraceConsumer returns a TraceConsumer that writes to w. ThestartIdx and endIdx are used for splitting large traces. They refer toindexes in the traceEvents output array, not the events in the trace input.
