The default RRA stores primary data points for an hour. More RRA can be added for a day, a week, a month, a quarter and a year. The created RRD is for an acquisition period much less than an hour, typically about some seconds or a few minutes.
This constructor neads an argument named step which is the period of acquisition which is second(s) or minute(mn).
