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 ¶
BlockProfile turns on CPU 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 ¶
CpuProfile turns on CPU profiling for nsec seconds and writes profile data to file.
func (*HandlerT) FreeOSMemory ¶
func (*HandlerT) FreeOSMemory()
FreeOSMemory returns unused memory to the OS.
func (*HandlerT) SetBlockProfileRate ¶
SetBlockProfileRate sets the rate of goroutine block profile data collection. rate 0 disables block profiling.
func (*HandlerT) SetGCPercent ¶
SetGCPercent sets the garbage collection target percentage. It returns the previous setting. A negative value disables GC.
func (*HandlerT) StartCPUProfile ¶
StartCPUProfile turns on CPU profiling, writing to the given file.
func (*HandlerT) StartGoTrace ¶
StartGoTrace turns on tracing, writing to the given file.
func (*HandlerT) StopCPUProfile ¶
StopCPUProfile stops an ongoing CPU profile.
func (*HandlerT) StopGoTrace ¶
StopTrace stops an ongoing trace.
func (*HandlerT) WriteBlockProfile ¶
WriteBlockProfile writes a goroutine blocking profile to the given file.
func (*HandlerT) WriteMemProfile ¶
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.
