[Howto] Install hddtemp

Hddtemp is a small utility that gives you the temperature of your hard drive by reading S.M.A.R.T. informations.

For compilling:

Code:

wget http://download.savannah.nongnu.org/releases/hddtemp/hddtemp-0.3-beta15.tar.bz2 bunzip2 hddtemp-0.3-beta15.tar.bz2 tar -xf hddtemp-0.3-beta15.tar cd hddtemp-0.3-beta15

Change in configure first string from /bin/sh to /opt/bin/bash

Code:

./configure --prefix=/opt --build=mips make sudo cp src/hddtemp /opt/bin/ wget http://www.guzu.net/linux/hddtemp.db sudo cp hddtemp.db /opt/etc/ sudo chmod a+s /opt/bin/hddtemp

After that you can see the temperature of your HDD via command:

Code:

hddtemp -f /opt/etc/hddtemp.db /dev/ide/host2/bus0/target0/lun0/disc

/dev/ide/host2/bus0/target0/lun0/disc: HDT722516DLAT80: 44?C

You must install buildroot package for compilling hddtemp.

RRDtool for creating graph

For creating graph of HDD temperature we can use rrdtool (original script is here)

How to install:

1. ipkg install rrdtool perl and setup cron like desribed on this forum
2.

Code:

sudo rrdtool create /opt/var/lib/rrd/hddtemp_hda.rrd -s 300 DS:hda:GAUGE:600:0:100 RRA:AVERAGE:0.5:1:576 RRA:AVERAGE:0.5:6:672 RRA:AVERAGE:0.5:24:732 RRA:AVERAGE:0.5:144:1460

3. Then create hddtemp.pl and copy it to /opt/etc/cron.5mins

Code:

#!/opt/bin/perl # # Copyright Martin Pot 2003 # http://martybugs.net/linux/hddtemp.cgi use RRDs; # define location of rrdtool binary my $rrdtool = '/opt/bin/rrdtool'; # define location of rrdtool databases my $rrd = '/opt/var/lib/rrd'; # define location of images my $img = '/shares/MYVOLUME1/MYSHARE1/images/'; # define image size parameters my $size = '-h 80 -w 600'; ## HDD Temperatures ######################### # get hdd temp for master drive on secondary IDE channel my $hda=`/opt/bin/hddtemp -f /opt/share/misc/hddtemp.db -n /dev/ide/host2/bus0/target0/lun0/disc`; # remove eol chars and white space $hda =~ s/[\n ]//g; print "hda temp: $hda degrees C\n"; # insert value into rrd `$rrdtool update $rrd/hddtemp_hda.rrd -t hda N:$hda`; ################################################ # daily hdd temp graph RRDs::graph "$img/hddtemp-day.png", "--lazy", "-t", "HDD Temperatures", "-h", "200", "-w", "600", "-a", "PNG", "-v", "degrees C", "DEF:hda=$rrd/hddtemp_hda.rrd:hda:AVERAGE", "LINE2:hda#0000FF:hda 160Gb-Hitachi", "GPRINT:hda:MIN: Min hda\\: %2.lf", "GPRINT:hda:LAST: Current hda\\: %2.lf degrees C\\n"; if ($ERROR = RRDs::error) { print "$0: unable to generate graph: $ERROR\n"; } # weekly system load graph RRDs::graph "$img/hddtemp-week.png", "-s", "-1week", "--lazy", "-t", "HDD Temperatures", "-h", "200", "-w", "600", "-a", "PNG", "-v", "degrees C", "DEF:hda=$rrd/hddtemp_hda.rrd:hda:AVERAGE", "LINE2:hda#0000FF:hda 120Gb-SYS-Seagate", "GPRINT:hda:MIN: Min hda\\: %2.lf", "GPRINT:hda:MAX: Max hda\\: %2.lf", "GPRINT:hda:LAST: Current hda\\: %2.lf degrees C\\n"; if ($ERROR = RRDs::error) { print "$0: unable to generate graph: $ERROR\n"; } # monthly system load graph RRDs::graph "$img/hddtemp-month.png", "-s", "-1month", "--lazy", "-t", "HDD Temperatures", "-h", "200", "-w", "600", "-a", "PNG", "-v", "degrees C", "DEF:hda=$rrd/hddtemp_hda.rrd:hda:AVERAGE", "LINE2:hda#0000FF:hda 120Gb-SYS", "GPRINT:hda:MIN: Min hda\\: %2.lf", "GPRINT:hda:MAX: Max hda\\: %2.lf", "GPRINT:hda:LAST: Current hda\\: %2.lf degrees C\\n"; if ($ERROR = RRDs::error) { print "$0: unable to generate graph: $ERROR\n"; } # yearly system load graph RRDs::graph "$img/hddtemp-year.png", "-s", "-1year", "--lazy", "-t", "HDD Temperatures", "-h", "200", "-w", "600", "-a", "PNG", "-v", "degrees C", "DEF:hda=$rrd/hddtemp_hda.rrd:hda:AVERAGE", "LINE2:hda#0000FF:hda 120Gb-SYS-Seagate", "GPRINT:hda:MIN: Min hda\\: %2.lf", "GPRINT:hda:MAX: Max hda\\: %2.lf", "GPRINT:hda:LAST: Current hda\\: %2.lf degrees C\\n"; if ($ERROR = RRDs::error) { print "$0: unable to generate graph: $ERROR\n"; }

4. Change path to store images in string to somewhere in your webserver directory for accessing outside:

Code:

my $img = '/shares/MYVOLUME1/MYSHARE1/images/';

5. Now you can see graph of temperature of your disk. Images update every 5 mins with cron.

S.M.A.R.T. not available

When I try, I get this:

Code:

[admin@(none) root]$ hddtemp -f /opt/etc/hddtemp.db /dev/discs/disc0/disc /dev/discs/disc0/disc: Hitachi HDT725032VLAT80: S.M.A.R.T. not available

Am I missing anything ?

AFAIK not all usb converters let the SMART info to pass through. May be you have bad luck...

I think, in this case there is no temperature sensor at the disk. But I see it for first time. All modern HDD's have this sensor.

HDDTemp is not working via USB. Only pata, sata, scsi and sas interfaces are supported, but only directly.

I get the following error!

For Seagate Free Agent (using smartctl in linux):
# smartctl -d sat /dev/sdb --all -T permissive

for me:
smartctl -d sat /dev/sdb --all -T permissive | grep 194 | cut -d: -f3 | awk '{print $11}'

prints the disk temperature

Check temp periodically and email if too hot...

Would anyone be interested in a how-to on this? It wasn't complicated, but it's handy for those warm days when my girlfriend forgets to open a window :)

I just noticed that the buildrood package is HUGE... I rather not install this, just for compiling this... are there any precompiled packages available?

Memory leak with digitemp and rrd

I'm losing 4-8 MB of memory with the attached script using this firmware on a WL-500GP v2. Since I'm running it every two minutes from cron, it eats up my memory in a day and the router either reboots or becomes inaccessible and have to cut the power.

I'm not an experienced Linux user. Tried ps aux, it doesn't show a change over time. Tried to call digitemp and rrdupdate from command line, no memory leak happens then.

Could you gurus take a look at my script and point out any suspicious lines or show me more ways to investigate this? TIA.

Code:

#!/bin/sh log="/opt/var/log/temperature.log" err_log="/opt/var/log/digitemp.log" home="/opt/var/lib/rrd/digitemp" date=`date "+%Y-%m-%d %H:%M:%S"` t=`/opt/bin/digitemp_DS2490 -q -a -o"%R %4.1C" -c ${home}/.digitemprc` # Loop, read each valua and add it to the database. Odd values are sensor ID. E$ i=1 echo -n "$date" >> $log for LINE in $t ; do let "odd = $i % 2" if [ $odd -eq 1 ]; then Sensor=$LINE else Temperature=$LINE # heartbeat on every 60s ( 1min.) # 1:1500 -> 1500 sample per every 1min -> 25h ( 1 day + 1 hour ) # 5:2160 -> 2100 sample per every 5min -> 180h ( 1 week + 0.5 day$ # 15:3024 -> 3024 sample per every 15min -> 756h ( 1 month + 0.5 day$ # 240:2190 -> 2190 sample per every 4h -> 8760h ( 365 days) if [ ! -e ${home}/${Sensor}.rrd ]; then echo "Creating new database for Sensor $Sensor " >> $err_log /opt/bin/rrdtool create ${home}/${Sensor}.rrd \ --step 60 \ DS:temp:GAUGE:300:-40:100 \ RRA:AVERAGE:0.5:1:1500 \ RRA:AVERAGE:0.5:5:2160 \ RRA:AVERAGE:0.5:15:3024 \ RRA:AVERAGE:0.5:240:2190 fi echo -n ",${Sensor},${Temperature}" >> $log /opt/bin/rrdupdate ${home}/${Sensor}.rrd N:${Temperature} fi let i=i+1 done echo "" >> $log
