<p class="MsoNormal">Hey everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I created a custom test and RRD definition because I wanted to reduce the interval time on a few graphs from 5 minute resolution to 1 minute. I got the data to be logged once every minute, which I verified is hitting the RRD. The problem
is that when I view the graph it’s still got a resolution of 5 minutes. <o:p></o:p></p>

<p class="MsoNormal">I had read that RRDTool should use the lowest resolution available, which is 1 minute for this RRD. So why are the graphs not going less than 5 minute intervals when zooming in? Any ideas?<o:p></o:p></p>
