Variables

var Handler = new(HandlerT)

Handler is the global debugging handler.

Functions

func APIs

func APIs() []rpc.API

APIs return the collection of RPC services the tracer package offers.

Types

type HandlerT

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

HandlerT implements the debugging API. Do not create values of this type, use the one in the Handler variable instead.

func (*HandlerT) BlockProfile

func (*HandlerT) BlockProfile(file string, nsec uint) error

BlockProfile turns on goroutine profiling for nsec seconds and writes profile data to file. It uses a profile rate of 1 for most accurate information. If a different rate is desired, set the rate and write the profile manually.

func (*HandlerT) CpuProfile

func (h *HandlerT) CpuProfile(file string, nsec uint) error

CpuProfile turns on CPU profiling for nsec seconds and writes profile data to file.

func (*HandlerT) FreeOSMemory

func (*HandlerT) FreeOSMemory()

FreeOSMemory forces a garbage collection.

func (*HandlerT) GcStats

func (*HandlerT) GcStats() *debug.GCStats

GcStats returns GC statistics.

func (*HandlerT) GoTrace

func (h *HandlerT) GoTrace(file string, nsec uint) error

GoTrace turns on tracing for nsec seconds and writes trace data to file.

func (*HandlerT) MemStats

func (*HandlerT) MemStats() *runtime.MemStats

MemStats returns detailed runtime memory statistics.

func (*HandlerT) MutexProfile

func (*HandlerT) MutexProfile(file string, nsec uint) error

MutexProfile turns on mutex profiling for nsec seconds and writes profile data to file. It uses a profile rate of 1 for most accurate information. If a different rate is desired, set the rate and write the profile manually.

func (*HandlerT) SetBlockProfileRate

func (*HandlerT) SetBlockProfileRate(rate int)

SetBlockProfileRate sets the rate of goroutine block profile data collection. rate 0 disables block profiling.

func (*HandlerT) SetGCPercent

func (*HandlerT) SetGCPercent(v int) int

SetGCPercent sets the garbage collection target percentage. It returns the previous setting. A negative value disables GC.

func (*HandlerT) SetMutexProfileFraction

func (*HandlerT) SetMutexProfileFraction(rate int)

SetMutexProfileFraction sets the rate of mutex profiling.

func (*HandlerT) Stacks

func (*HandlerT) Stacks(filter *string) string

Stacks returns a printed representation of the stacks of all goroutines. It also permits the following optional filters to be used:

• filter: boolean expression of packages to filter for

func (*HandlerT) StartCPUProfile

func (h *HandlerT) StartCPUProfile(file string) error

StartCPUProfile turns on CPU profiling, writing to the given file.

func (*HandlerT) StartGoTrace

func (h *HandlerT) StartGoTrace(file string) error

StartGoTrace turns on tracing, writing to the given file.

func (*HandlerT) StopCPUProfile

func (h *HandlerT) StopCPUProfile() error

StopCPUProfile stops an ongoing CPU profile.

func (*HandlerT) StopGoTrace

func (h *HandlerT) StopGoTrace() error

StopTrace stops an ongoing trace.

func (*HandlerT) WriteBlockProfile

func (*HandlerT) WriteBlockProfile(file string) error

WriteBlockProfile writes a goroutine blocking profile to the given file.

func (*HandlerT) WriteMemProfile

func (*HandlerT) WriteMemProfile(file string) error

WriteMemProfile writes an allocation profile to the given file. Note that the profiling rate cannot be set through the API, it must be set on the command line.

func (*HandlerT) WriteMutexProfile

func (*HandlerT) WriteMutexProfile(file string) error

WriteMutexProfile writes a goroutine blocking profile to the given file.
