[rrd-users] Adding aberrant detection to existing RRD files

[Livio Zanol Puppim]

Errata:

 74335473981897 - 74335472553937 = 1427960
1427960/300(step) = 4759,86666... (the value you've *got*)

-----------------------------------------------------

74335473981897*300 - 74335472553937*300 = (74335473981897 -
74335472553937)*300/300(step) = 1427960
