    Post [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';

    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.

    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

  10. #10

    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

  11. #11
    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.
