Heh, yes, quite a simple 'transformation' if you know the aggregation step<div>As you can see in my discussion with Simon, it's quite hard (or impossible) to get current graph's step value from rrdtool and the only option remaining is to control the step externally.</div>
<div>Or maybe the step can be calculated based on graph date range? If so, what's the algorithm rrdtool uses?</div><div><br></div><div>R</div><div><br><div class="gmail_quote">On Sun, May 20, 2012 at 5:50 PM, Tobias Oetiker <span dir="ltr"><<a href="mailto:tobi@oetiker.ch" target="_blank">tobi@oetiker.ch</a>></span> wrote:<br>

</div>well the 'transformation' is pretty simple, you just multiply the<br>
average rate over the periode you are interested in to get the sum<br>
... VDEF can help you ...<br>
