Can someone help me debug my rrd_HDtemp.pl?

Code:
# rrd_HDtemp.pl
/dev/hdb: open: No such file or directory

/dev/sda: open: No such file or directory

hda: 38, hdb: 0, sda: 0
hdt1:hdt2:hdt3
N:38:0:0
Error: RRDs::update for 'HDtemp' : tmplt contains more DS definitions than RRD
Error: RRDs::graph failed for 'day' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'week' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'month' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'year' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'


Seems to be correctly reading the temp of the sole drive (/dev/hda) at 38 °C, but any ideas about the string of errors? Also, here is a screenshot of the output:

Also, if I use hddtemp it agrees (38 °C):

Code:
# hddtemp /dev/hda
/dev/hda: WDC WD5000AAKB-00YSA0: 38 C


The data displayed as well as the drive name is from my old R5F27. I installed a new HD when I installed R5.5 and copied my /myth (with backup) to the new drive. Anyway, rrd isn't seeing the new drive at all.

Thoughts are welcome. In case someone asks, here in my /etc/rrd.config (I only modded the MB and CPU temp lines):

I'll give you a hint....

;-)

Unfortunately you need to do this in the script until I get a chance to publish the versions which use /etc/rrd.config properly.

After backing up my current /etc/rrd.config and /usr/local/bin/rrd* I replaced them with the ones from the file you emailed to me.

Here is the output when I try to query the HDtemp.pl

Code:
# rrd_HDtemp.pl
/dev/hdb: open: No such file or directory

hda: 35, hdb: 0
hdt1:hdt2
N:35:0
Error: RRDs::update for 'HDtemp' : tmplt contains more DS definitions than RRD

Error: RRDs::graph failed for 'week' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'month' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'

It's working now!

I simply used your /etc/rrd.config (modded to use sensors for my MBtemps and I removed the "hdb" from the devices to measure line

Code:
$HDT_dev = 'hda';               # devices to measure


I also overwrote the R5.5 out-of-the-box /usr/local/bin/rrd_HDtemp.pl with the one you supplied.

I didn't overwrite any of the other ones. Also had to mod my rrd_MBtemp.pl as described in this thread to get it to work with my old hardware. Anyway, thanks! Hell, here it is in its entirety:

Well that was kind of the idea of those fixes, moving all the configuration to the /etc/rrd.config file... In that set there are about 4-5 files I changed along those lines. Things like fan and temperature sensor ordering, actual disk drives (up to 6), and even the command and argument for the MBTemp and MBFan without hacking the script directly.

There are a couple ways you could do this. For example a trivial script which you can use as your $MBT_prog:
Code:
#!/bin/bash
case $1 in
1) sensors | grep "M/B Temp" | cut -c 15-17 ;;
2) sensors | grep "CPU Temp" | cut -c 15-17 ;;
*) ;;
esac

The key is that the more generic we can make the scripts and the less you have to fiddle with them scripts in a custom way and can just set in the config file the better.

OBTW - For anyone else who want to try these they're available here: rrd_updates.tar.gz

That is a more elegant solution. I just have no experience writing .pl files and as such, next to no understanding of what needs to happen for them to work. Thanks again, tjc. :)

Well definitely back up your old rrd_*.pl and rrd.config and give those a shot. You can drop that little shell script below in /usr/local/bin as something like sensors_temp.sh and adjust rrd.conf as needed. It should be trivial since they're just variable settings... Those work for me but I need to get some other people trying them.

BTW - Does mbmon not work for your motherboard at all? What happens if you run
Code:
mbmon -d

@tjc -

Code:
# mbmon -d
SMBus[NVidia nForce2] found, but No HWM available on it!!
No Hardware Monitor found!!
InitMBInfo: Success


In contrast, lm-sensors gives:
Code:
# sensors

Adapter: ISA adapter
VCore 1:     +1.74 V  (min =  +0.00 V, max =  +4.08 V)
VCore 2:     +4.08 V  (min =  +0.00 V, max =  +4.08 V)
+3.3V:       +3.36 V  (min =  +0.00 V, max =  +4.08 V)
+5V:         +5.05 V  (min =  +0.00 V, max =  +6.85 V)

-12V:        +3.93 V  (min = -27.36 V, max =  +3.93 V)
-5V:         +4.03 V  (min = -13.64 V, max =  +4.03 V)
Stdby:       +6.85 V  (min =  +0.00 V, max =  +6.85 V)
VBat:        +4.08 V
fan1:       3245 RPM  (min =    0 RPM, div = 2)
fan2:       2556 RPM  (min =    0 RPM, div = 4)
M/B Temp:    +18.0 C  (low  =  -1.0 C, high = +127.0 C)  sensor = thermal diode
CPU Temp:    +34.0 C  (low  =  -1.0 C, high = +127.0 C)  sensor = transistor
Temp3:        -1.0 C  (low  =  -1.0 C, high = +127.0 C)  sensor = disabled
cpu0_vid:   +1.750 V


I know mbmon works, perhaps I'm missing a kernel mod? In any case, when it did work in the past, the CPU/MB temps were mixed up.

You might try sending it directly to ISA and that chip...
Code:
mbmon -d -I -p it87

This thread has the full walk through: http://knoppmyth.net/phpBB2/viewtopic.php?t=18536

As for being mixed up, thats why the new configurable script let you juggle sensor order. I'm "lucky" that my production and test boxes are rather different on this count, which inspired me to sort it out and let me test that it worked.

TJC,

I am using your updated scripts now, and I modified the rrd.config to use hda and sda as the two monitored drives. Here's the output:

Code:
hda: 41, sda: 37
hdt1:hdt2
N:41:37
Error: RRDs::update for 'HDtemp' : tmplt contains more DS definitions than RRD
Error: RRDs::graph failed for 'day' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'week' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'month' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'
Error: RRDs::graph failed for 'year' : No DS called 'hdt2' in '/myth/rrd/log/HDtemp.rrd'


Update: Deleting the existing HDtemp.rrd file allowed the new code to run. Tetchy thing, this RRD...[/b]

since I have four hard drives installed i tried to add all hdds in the $dev array in rrd_HDtemp.pl. if I use only three devices in the list it works ok, but if I use more than that(ie 4) the script fails:

I connot find anything in the script that limits the array to three elements?
I use R5.5

I even tried the new version of rrd_HDtemp.pl and added the array in rrd.config:
Code:
$HDT_dev = 'hda hdb sda sdb';          # devices to measure
@HDT_colors = ('#0000FF', '#00FF00', '#FF0000', '#FF00FF', '#00FFFF', '#FFFF00'$


but still i get the same error message(see previous post) when executing rrd_HDtemp.pl

You may need to purge the DB for that and start fresh.
