perhaps this has been covered. If so.. well.. I tried.

I love the RRDtool system graphs, but mbmon did not work with my hardware. after running sensors-detect, the system did find a suitable driver to monitor my hardware.

So I ran sensors-detect, allowed the config to modify the modules file, and rebooted to load the modules.

Then I made the following changes to /etc/rrd.config
(near the bottom of the file)
Code:
 $MBT_prog = 'sensors'; 

$MBF_prog = 'sensors'; 

then the following changes to /usr/local/bin/rrd_MBtemp.pl
Code:
$mbt1 = `$MBT_prog|grep -i "sys temp" |cut -c 15-17`;
    $mbt2 = `$MBT_prog|grep -i "cpu temp" |cut -c 13-17`;
    $mbt3 = `$MBT_prog|grep -i "aux temp" |cut -c 13-17`;


then these changes to /usr/local/bin/rrd_MBfan.pl
Code:
    $mbf1 = `$MBF_prog |grep -i "aux fan"|cut -c 11-15`;  # Motherboard fan
    $mbf2 = `$MBF_prog |grep -i "cpu fan"|cut -c 11-15`;  # CPU fan
    $mbf3 = `$MBF_prog |grep -i "case fan"|cut -c 11-15`;  # Case fan


Worked for me. Your results may vary.

Edit: sensors-detect not sensors-config. whoops.

What are your hardware details?

This is an MSI K9NBPM2-FID board, AM2 socket with AMD Ath 64 X2 4000+ 2.1G

My motherboard is an ASUS P5P800-SE and mbmon doesn't work on it either. I took a slightly different approach than Heem did, but at the core we both are using sensors instead of mbmon to obtain CPU & MOBO temp and fan info.

When I run mbmon on my system I get the following:
Code:
root@mythhd:/# mbmon
eNo Hardware Monitor found!!
InitMBInfo: Success
root@mythhd:/# echo $?
1


So one could revise the rrd script to automatically decide weather to use mbmon or sensors, but you also need to run sensors_detect as a 1-time configuration setup.

Before I made the change to use sensors instead of mbmon I would periodically find mbmon stuck in a loop using 100% of one of my cores...

Using mbmon, my CPU temp is always 255. I configured sensors, loaded-up the correct modules (it87) and sensors works just fine now:

Code:
$ sensors
it8712-isa-0d00
Adapter: ISA adapter
VCore 1:   +1.74 V  (min =  +4.08 V, max =  +4.08 V)   ALARM
VCore 2:   +4.08 V  (min =  +4.08 V, max =  +4.08 V)   ALARM
+3.3V:     +3.36 V  (min =  +4.08 V, max =  +4.08 V)   ALARM
+5V:       +4.95 V  (min =  +6.85 V, max =  +6.85 V)   ALARM
+12V:     +12.35 V  (min = +16.32 V, max = +16.32 V)   ALARM
-12V:      +3.93 V  (min =  +3.93 V, max =  +3.93 V)   ALARM
-5V:       +4.03 V  (min =  +4.03 V, max =  +4.03 V)   ALARM
Stdby:     +6.85 V  (min =  +6.85 V, max =  +6.85 V)   ALARM
VBat:      +4.08 V
fan1:     3245 RPM  (min =    0 RPM, div = 2)
fan2:     2537 RPM  (min =    0 RPM, div = 4)
fan3:        0 RPM  (min =    0 RPM, div = 2)
M/B Temp:    +38 C  (low  =    -1 C, high =    -1 C)   sensor = diode
CPU Temp:    +39 C  (low  =    -1 C, high =    -1 C)   sensor = thermistor
Temp3:        -1 C  (low  =    -1 C, high =    -1 C)   sensor = disabled   ALARM


I modified my /etc/rrd.config as you suggested and as well my /usr/local/bin/rrd_MBtemp.pl relevant info below:

Code:
$mbt1 = `$MBT_prog | grep "M/B Temp" | cut -c 15-17';
$mbt2 = `$MBT_prog | grep "CPU Temp" | cut -c 15-17';


I skipped the /usr/local/bin/rrd_MBfan.pl for the moment. The output in the webpage hasn't changed to reflect these modifications even after a reboot:
Image

I will admit to being totally new to these .pl files... is it obvious what I did wrong from the info I posted here?

make sure you have the correct single quote at the end of that statement:

Quote:
$mbt1 = `$MBT_prog | grep "M/B Temp" | cut -c 15-17'


should be

$mbt1 = `$MBT_prog | grep "M/B Temp" | cut -c 15-17`

also, try running that command directly from the command line, make sure you get just the number:

sensors |grep "M/B Temp"| cut -c 15-17

you might have to change 15-17 to match the output it creates.
you want just a number here.

Wow... I didn't see the difference between the ' that I used and the ` that it's supposed to be! I corrected it so it now reads:
Code:
$mbt1 = `$MBT_prog | grep "M/B Temp" | cut -c 15-17`;
$mbt2 = `$MBT_prog | grep "CPU Temp" | cut -c 15-17`;


I did test the cut command and it indeed yields only a number"
Code:
$ sensors | grep "M/B Temp" | cut -c 15-17
40
$ sensors | grep "CPU Temp" | cut -c 15-17
41


Is there something I need to restart to get the changes to commit or is it "live" everything I hit the webpage? I ask because even after these changes, the output is still incorrect.

Thanks again!

it takes 5 minutes to update. they are cron jobs that run. you could manually run the /usr/local/bin/rrd_MBtemp.pl file - but by the time you get this it's probably already been 5 minutes ;)

Cool... it's been over an hour and the displayed CPU temps are unchanged:

Come to think of it, the data isn't getting updated at all in the mb page.

looks like "mb temp" is working, no? look more closely at cpu temp.

matter of fact, paste your rrd.config and your rrd_MBtemp.pl file

I don't think either one is working; that screenshot was taken yesterday (Wed) but there is only data in it for Tue. All the other rrd modules are giving data for the current day except cpu temp/mb temp so I'm sure I messed up something.

yours looks just like mine.

Try running the rrd_MBtemp.pl manually - a few times. see what you get.

Interesting idea:

Code:
$ rrd_MBtemp.pl
Parse error in chip name `3'
