Functions ¶

func Exit ¶

func Exit()

Exit stops all running profiles, flushing their output to the respective file.

func LoudPanic ¶

func LoudPanic(x interface{})

LoudPanic panics in a way that gets all goroutine stacks printed on stderr.

func Setup ¶

func Setup(debugCfg *Config) error

Setup initializes profiling ,It should be called as early as possible in the program.

func StartPProf ¶

func StartPProf(address string)

Types ¶

type Config ¶

type Config struct {
	Pprof            bool   `mapstructure:"debug-pprof"`
	PprofPort        int    `mapstructure:"debug-pprofport"`
	PprofAddr        string `mapstructure:"debug-pprofaddr"`
	Memprofilerate   int    `mapstructure:"debug-memprofilerate"`
	Blockprofilerate int    `mapstructure:"debug-blockprofilerate"`
	Cpuprofile       string `mapstructure:"debug-cpuprofile"`
	Trace            string `mapstructure:"debug-trace"`
}

func DefaultConfig ¶

func DefaultConfig() *Config

type DebugArgs ¶

type DebugArgs struct {
	File string
	Nsec uint64
}

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(args DebugArgs, reply *bool) 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(args DebugArgs, reply *bool) error

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

func (*HandlerT) FreeOSMemory ¶

func (*HandlerT) FreeOSMemory(ignore string, reply *bool) error

FreeOSMemory returns unused memory to the OS.

func (*HandlerT) GcStats ¶

func (*HandlerT) GcStats(ignore string, reply *debug.GCStats) error

GcStats returns GC statistics.

func (*HandlerT) GoTrace ¶

func (h *HandlerT) GoTrace(args DebugArgs, reply *bool) error

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

func (*HandlerT) MemStats ¶

func (*HandlerT) MemStats(ignore string, reply *runtime.MemStats) error

MemStats returns detailed runtime memory statistics.

func (*HandlerT) MutexProfile ¶

func (*HandlerT) MutexProfile(args DebugArgs, reply *bool) 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) SetGCPercent ¶

func (*HandlerT) SetGCPercent(v int, reply *int) error

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

func (*HandlerT) Stacks ¶

func (*HandlerT) Stacks(ignore string, reply *[]byte) error

Stacks returns a printed representation of the stacks of all goroutines.

func (*HandlerT) StartCPUProfile ¶

func (h *HandlerT) StartCPUProfile(file string, reply *bool) error

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

func (*HandlerT) StartGoTrace ¶

func (h *HandlerT) StartGoTrace(file string, reply *bool) error

StartGoTrace turns on tracing, writing to the given file.

func (*HandlerT) StopCPUProfile ¶

func (h *HandlerT) StopCPUProfile(ignore string, reply *bool) error

StopCPUProfile stops an ongoing CPU profile.

func (*HandlerT) StopGoTrace ¶

func (h *HandlerT) StopGoTrace(ignore string, reply *bool) error

StopGoTrace stops an ongoing trace.

func (*HandlerT) WriteMemProfile ¶

func (*HandlerT) WriteMemProfile(file string, reply *bool) 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.
