func StartServer(port int)

StartServer starts a PProf server in background. Endpoints usage example:

curl http://localhost:6063/debug/pprof/allocs > allocs.pprof
pprof -http=: allocs.pprof

wget http://localhost:31415/debug/pprof/goroutine
pprof -http=: goroutine

Types

type Stoppable

type Stoppable interface {
	Stop()
}

func ProbeCPU

func ProbeCPU() Stoppable

ProbeCPU is used like the following:

defer pprof.ProbeCPU.Stop()

When the caller reaches its function end, the defer executes Stop() that writes the file "cpu.pprof". To visualize "cpu.pprof" use the pprof tool:

cd ~/go
go get -u github.com/google/pprof
cd -
pprof -http=: cpu.pprof
