Try this: rrdtool create icmp.rrd \ -s 60 --start 1071682900 \ DS:one:GAUGE:120:0:U \ DS:two:GAUGE:120:0:U \ DS:three:GAUGE:120:0:U \ DS:four:GAUGE:120:0:U \ RRA:AVERAGE:0.5:1:720 \ RRA:AVERAGE:0.5:5:720 \ RRA:AVERAGE:0.5:30:336 \ RRA:AVERAGE:0.5:120:360 \ RRA:AVERAGE:0.5:1440:365 \
maybe it's a problem with your heartbeat/step combination. perl e 'print scalar localtime(1071682900)."\n";' solves your second issues.
