Other Tips

monitor.lua will cache last 5 seconds data by default, you can change it by monitor.cacheSeconds = 6 to cache 6 seconds data

Never worry about if sum number is too big, because lua max number is math.pow(2, 1023) * 1.9999..., even your qps is billion, you can run billion years without restart
