Types ¶
type Profile ¶
type Profile struct {
// contains filtered or unexported fields
}
Profile represents an active profiling session.
type Stopper ¶
type Stopper interface {
Stop()
}
Stopper interface wraps the method Stop.
func StartProfile ¶
StartProfile starts a new profiling session. The caller should call the Stop method on the value returned to cleanly stop profiling.
go func() {
var profiler proc.Stopper
signals := make(chan os.Signal, 1)
signal.Notify(signals, syscall.SIGUSR1, syscall.SIGUSR2, syscall.SIGTERM)
for {
v := <-signals
switch v {
case syscall.SIGUSR2:
if profiler == nil {
profiler = proc.StartProfile()
} else {
profiler.Stop()
profiler = nil
}
}
}
}()
