A combination of unfortunate accidents with programming off-by-one errors and people not understanding the fencepost error http://en.wikipedia.org/wiki/Off-by-one_error#Fencepost_error What usually helps is to ask for {$start_you_want}+{$offset} to {$end_you_want}-{$offset} where offset is choosen such a way that it does not make another RRA more suitable. Generally speaking "1" is already enough. HTH Alex _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
