Metrics

gomet is the metrics collector designed to see what goroutines do.

ussage:

at the beginning of program setup gomet specifying stats period:

tickCh := gomet.Setup(time.Second) 

every second channel tickCh produces stats data, so you can listen on channel in some goroutines

for tick := range tickCh {
	saveToCSV(tick)
	// or store in some other places
}

Tick contains stats for each groups, see godoc for details.

At the begining of the goroutine create a new Meter, at the end of goroutine close the Meter:

m := New("NetWorker")
defer m.Close()

Than Specify states of goroutine:

m.State("wait on chan")
//data := <- dataCh
m.State("payload")
// payload(data)

To get stats how long data spend on channel use the ChanIn() and ChanOut() methods (see godoc)
