  • Ik kreeg helaas helaas niets te zien in de overzichten, dus moesten we gaan controleren. Dit kan je heel makkelijk doen door het script te starten:
    # cd /usr/local/share/munin/plugins
    # ./hddtemp_smartctl

    Opmerking: Een heleboel foutmeldingen, en laat de read permissions je niet misleiden. Het blijkt dat ik nog smartmon tools moest installeren.

  • De meldingen kloppen deels wel, hij kan de data niet verkrijgen en daardoor denkt FreeBSD dat hij onvoldoende permissies heeft om de getallen uit te lezen. Je installeert smart_ctl door de volgende commando's in te voeren:
    # cd /usr/ports/sysutils/smartmontools
    # make install clean


  • Houdt de standaard opties aan voor smartctl
  • Smart monitoring tools zijn succesvol geinstalleerd:
  • Nogmaals testen doormiddel van het commando:
    #
  • Dit is een script die ik zelf heb gefabriceerd op basis van hddtemp_smartctl, genaamd: poweron_smartctl

    #!/usr/local/bin/perl –w
    # -*- perl -*-

    =head1 NAME

    poweron_smartctl - Plugin to monitor harddrive temperatures through
    SMART

    =head1 CONFIGURATION

    This plugin needs to run as root or some other user that has access to
    the harddrive devices.

    The following environment variables are used
    smartctl - path to smartctl executable
    drives - List drives to monitor. E.g. "env.drives hda hdc".
    type_$dev - device type for one drive, e.g. "env.type_sda 3ware,0"
    or more typically "env.type_sda ata" if sda is a SATA disk.
    args_$dev - additional arguments to smartctl for one drive,
    e.g. "env.args_hda -v 194,10xCelsius". Use this to make
    the plugin use the --all or -a option if your disk will
    not return its temperature when only the -A option is
    used.
    dev_$dev - monitoring device for one drive, e.g. twe0

    If the "smartctl" enviroment variable is not set the plugin will
    search your $PATH, /usr/bin, /usr/sbin, /usr/local/bin and
    /usr/local/sbin for a file called "smartctl", and use that.

    If the "drives" environment variable is not set, the plugin will
    attempt to search for drives to probe.

    =head1 NOTES

    Note for users of RAID controllers (smartmontools currently only
    supports 3ware): you can specify the drives attached to your RAID
    controller(s) as raiddev_num (e.g. sda_0). Then you must specify the
    type like this: type_sda_0 3ware,0.

    Recent versions of the kernel driver use a separate major device
    number for monitoring purposes, like /dev/twe or /dev/twa. This
    can be put in the e.g. dev_sda environment variable, to allow the user
    to keep sda as the name of the disk.

    To avoid spinning up sleeping disks smartctl will use the –nocheck
    parameter. If this parameter isn't supported by your version of
    smartctl then hdparm will be used. Note that hdparm isn't available
    on all platforms.
