Sorry. Now i have one simpler.

usr/bin/rrdtool graph /tmp/a.png \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="LSPRO - Fan Speed" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="FAN - RPM" \
--slope-mode \
DEF:a="/usr/share/cacti-0.8.6j/rra/lspro_fan_27.rrd":fan:AVERAGE \
GPRINT:a:AVERAGE:"RPM\:%8.2lf %s"



It still seg faults :/
As a said every time i try to use GPRINT it seg faults.
