<p class=MsoNormal>Hi Joghan,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As far as I can understand, your problem is this: “last_update
= 12263196<b>14</b>”.<o:p></o:p></p>
<p class=MsoNormal>As you have a step of 100, and the rrdtool stores the values
at multiples of the step, when you send a value in a timestamp that isn’t a
multiple of your step (100 in your case), it estimates the values at that time
and stores it.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>You can try and set the update time of rrdupdate to be a
multiple of 100 (the one previous to the one that you are at that moment). But
try to use a value retrieved by that “rounded” time, e.g., instead of change
the update time, change the retrieve time to something closer to the multiple
of 100 (but use the multiple of 100 as the update time).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I hope am right and this helps you.<span style='font-size:
