Hmmm, I installed a new rrdtool and enabled aberrant detection, but seems
there is nothing new on the generated graphic, no upper/lower boundary, no
Does it means rrdtool needs to reach the limit of the 5 days "length"
(RRA:HWPREDICT:1440:0.1:0.0035:288 ) to begin to generate upper/lower
boundary and alert?
