Looking at one of the scripts, I see this : if [ ! -s $DATABAZA ] ; then rrdtool create --step 60 $DATABAZA \ DS:mem_used:GAUGE:60:0:1553384 \ DS:swap_used:GAUGE:60:0:506036 \ RRA:AVERAGE:0.5:1:60 fi If I read that correctly (someone correct me if I'm wrong), the heartbeat is 60 seconds, which means that if your update arrives at 61 seconds then you've missed a sample and it stores NaN. Although you run the scripts at 1 minute intervals, they will not actually submit results at EXACTLY 60 second intervals - in practice updates are going to be 60s +/- a bit of variation. I suggest using a longer heartbeat, probably 2 or 3 minutes.
