There will stored all archives from each RRA in from two DS. When you fetch the data, you chose which RRA to be consulted.<br>=]<br><br><br><div class="gmail_quote">2010/8/18 tinsfci <span dir="ltr"><<a href="mailto:perlon@passagen.se">perlon@passagen.se</a>></span><br>

Hello,<br>
<br>
I can´t fin out how RRDtool "knows" which RRA to get data from if you for<br>
example has a setup of 4 RRA:AVERAGE:s, se below, (from the RRDtool<br>
tutorial):<br>
<br>
Let´s say I plot a graph from "now" to -1month, does RRDtool "automatically"<br>
use "no 3", or do i specify it somewhere?<br>
<br>
"no 1": 600 samples of 5 minutes (2 days and 2 hours)<br>
"no 2": 700 samples of 30 minutes (2 days and 2 hours, plus 12.5 days)<br>
"no 3": 775 samples of 2 hours (above + 50 days)<br>
"no 4": 797 samples of 1 day (above + 732 days, rounded up to 797)<br>
