Is it correct that the RRD would contain 1 year's worth of data points if I specify an RRA with a yearly average? Is keeping 1 year's work of 5 minute data points the only way to generate a yearly average graph?
It's not a problem to do so, I just want to be clear on the implementation, Thanks very much for your feedback.
