func StartProfilers

func StartProfilers(cpuProfilePath, memProfilePath, tracePath, fgprofPath string) (stopProfile func() error, err error)

StartProfilers starts various profilers and returns a function to stop them.

func StartTrace

func StartTrace(tracePath string) (stop func() error, err error)

StartTrace starts a program trace using the "runtime/trace" package. Returns a function to stop the trace.
