The most simple thing to is use this script (/usr/local/bin/hddtemps.mrtg):

    #!/bin/sh

    #in
    /usr/local/bin/hddtemp -n /dev/hde
    #out
    /usr/local/bin/hddtemp -n /dev/hdg
    #uptime
    uptime
    #hostname
    echo `hostname`: hde hdg temps

with the following mrtg.conf entry

    Target[hddtemp]: `/usr/local/bin/hddtemps.mrtg`
    Title[hddtemp]: System Harddisk Temperature
    PageTop[hddtemp]: <H1> System Harddisk temperatures </H1>
    MaxBytes[hddtemp]: 100
    Options[hddtemp]: nopercent, gauge
    Ylegend[hddtemp]: Graden Celsius
    ShortLegend[hddtemp]: Graden
    Legend1[hddtemp]: Temperatuur hde
    Legend2[hddtemp]: Temperatuur hdg
    Legend3[hddtemp]: leg3
    Legend4[hddtemp]: leg4
    LegendI[hddtemp]: hde:
    LegendO[hddtemp]: hdg:

I just use plain mrtg (no rrd) so the graphs are in the mrtg html tree...
