[rrd-users] Re: Help needed on rrdtool create and rrdtool update

[Serge Maandag]

Hmm, what I do see is that you have a heartbeat of 3600 secs. Your
updates (at least the first two ones, didn't check the other ones) on
the other hand are made with a 7200 sec interval. This is well over the
heartbeat threshold, so rrdtool will take the value for a NaN.

Read up on the heartbeat and the step @
