Easy fix fan/temp OS6 issues on x86 legacy #no support

I've installed OS6 on a pro2. As I don't have fan speed and CPU temp, I've made a small script to generate my own RRD.

First, we have to generate the cpu RRD and Temp RRD. I've created on /dashboard/frontview/stats/

rrdtool create fan.rrd --step 60 \
DS:rpm:GAUGE:120:0:5000 \
RRA:AVERAGE:0,5:1:2880 \
RRA:AVERAGE:0,5:30:384 \
RRA:AVERAGE:0,5:120:384 \
RRA:AVERAGE:0,5:1440:365 \
RRA:MAX:0,5:1:2880 \
RRA:MAX:0,5:30:384 \
RRA:MAX:0,5:120:384 \
RRA:MAX:0,5:1440:365 \
RRA:MIN:0,5:1:2880 \
RRA:MIN:0,5:30:384 \
RRA:MIN:0,5:120:384 \

and now CPU RRD:

rrdtool create temp_sys.rrd --step 60 \
DS:core0:GAUGE:120:0:100 \
DS:core1:GAUGE:120:0:100 \
DS:system:GAUGE:120:0:100 \
RRA:AVERAGE:0,5:1:2880 \
RRA:AVERAGE:0,5:30:384 \
RRA:AVERAGE:0,5:120:384 \
RRA:AVERAGE:0,5:1440:365 \
RRA:MAX:0,5:1:2880 \
RRA:MAX:0,5:30:384 \
RRA:MAX:0,5:120:384 \
RRA:MAX:0,5:1440:365 \
RRA:MIN:0,5:1:2880 \
RRA:MIN:0,5:30:384 \
RRA:MIN:0,5:120:384 \

Now it's time to create a script (update_rdd). This script gets temperature from CPU Core 0, CPU Core 1, System temperature and fan speed and updates de RRDs

#!/bin/sh
#####################################################
Coretemp1="/sys/devices/platform/coretemp.0/temp2_input"
Coretemp2="/sys/devices/platform/coretemp.0/temp3_input"
Systemp="/sys/devices/platform/it87.2576/temp2_input"
fan="/sys/devices/platform/it87.2576/fan1_input"
F=`cat $fan`
C1t=`cat $Coretemp1`
C1=`expr $C1t / 1000`
C2t=`cat $Coretemp2`
C2=`expr $C2t / 1000`
S=`cat $Systemp`
rrdtool update /frontview/dashboard/stats/temp_sys.rrd N:$C1:$C2:$S
rrdtool update /frontview/dashboard/stats/fan.rrd N:$F
##echo " CPU1=$C1 CPU2=$C2 SYS=$S "

So, We have the data on RRD. Now It's time to draw!. This example creates 2 simple PNGs from "now - 4 hours"

rrdtool graph /frontview/dashboard/stats/tempsys.png --title="Temperature" --start end-4h \
        --imgformat=PNG \
        --width=500 \
        --base=1000 \
        --height=120 \
        --interlaced \
        DEF:a=/frontview/dashboard/stats/temp_sys.rrd:core0:AVERAGE \
        DEF:b=/frontview/dashboard/stats/temp_sys.rrd:core1:AVERAGE \
        DEF:c=/frontview/dashboard/stats/temp_sys.rrd:system:AVERAGE \
        LINE1:a#800000:core0 \
        LINE1:b#00FF00:core1 \
        LINE1:c#FF0000:system \
        COMMENT:"Comments"
rrdtool graph /frontview/dashboard/stats/fan.png --title="Fan" --start end-4h \
        --imgformat=PNG \
        --width=500 \
        --base=1000 \
        --height=120 \
        --interlaced \
        DEF:a=/frontview/dashboard/stats/fan.rrd:rpm:AVERAGE \
        LINE1:a#800000:rpm \
        COMMENT:"Comments"

The last step it's call those scripts from crontab:

*/1 *   * * *   root /root/scripts/update_rrd
*/2 *   * * *   root /root/scripts/print_rrd

I've tried to change the images from original dashboard with this ones but it was much easier to generate a simple HTML and call this PNGs 8)
