    Exclamation lm-sensors issue.

    Hey guys, so I need something to monitor the temperature of my Ubuntu server and while doing research on this, lm-sensors came up. Basically I installed it like the guide said and proceeded to set up the sensors/detect them, but the process failed...Despite detecting my machine and a sensor or two (although it did say "No" to most things). See below for the log, does anyone know why the below occurred? Anyway to work around it?

    Code:
    damir@server3:~$ sudo sensors-detect
    # sensors-detect revision 5946 (2011-03-23 11:54:44 +0100)
    # System: Dell Computer Corporation OptiPlex GX150
    
    This program will help you determine which kernel modules you need
    to load to use lm_sensors most effectively. It is generally safe
    and recommended to accept the default answers to all questions,
    unless you know what you're doing.
    
    Some south bridges, CPUs or memory controllers contain embedded sensors.
    Do you want to scan for them? This is totally safe. (YES/no): YES

    Some Super I/O chips contain embedded sensors. We have to write to
    standard I/O ports to probe them. This is usually safe.
    Do you want to scan for Super I/O sensors? (YES/no): YES
    Probing for Super-I/O at 0x2e/0x2f
    Trying family `National Semiconductor'...                   Yes
    Found `Nat. Semi. PC87364 Super IO Fan Sensors'
        (but not activated)

    Trying family `National Semiconductor'...                   No
    Trying family `SMSC'...                                     No

    Trying family `ITE'...                                      No
    
    Some systems (mainly servers) implement IPMI, a set of common interfaces
    through which system health data may be retrieved, amongst other things.
    We first try to get the information from SMBIOS. If we don't find it
    there, we have to read from arbitrary I/O ports to probe for such
    interfaces. This is normally safe. Do you want to scan for IPMI
    interfaces? (YES/no): YES
    Probing for `IPMI BMC KCS' at 0xca0...                      No
    Probing for `IPMI BMC SMIC' at 0xca8...                     No
    
    Some hardware monitoring chips are accessible through the ISA I/O ports.
    We have to write to arbitrary I/O ports to probe them. This is usually
    safe though. Yes, you do have ISA I/O ports even if you do not have any
    ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES
    Probing for `National Semiconductor LM78' at 0x290...       No
    Probing for `National Semiconductor LM79' at 0x290...       No
    Probing for `Winbond W83781D' at 0x290...                   No
    Probing for `Winbond W83782D' at 0x290...                   No
    
    Lastly, we can probe the I2C/SMBus adapters for connected hardware
    monitoring devices. This is the most risky part, and while it works
    reasonably well on most systems, it has been reported to cause trouble
    on some systems.
    Do you want to probe the I2C/SMBus adapters now? (YES/no): YES

        (confidence 8, not a hardware monitoring chip)
    
    Sorry, no sensors were detected.
    Either your system has no sensors, or they are not supported, or
    they are connected to an I2C or SMBus adapter that is not
    supported. If you find out what chips are on your board, check
    http://www.lm-sensors.org/wiki/Devices for driver status.

    Hello Friend,

    Based on the website link: http://lm-sensors.org/wiki/Devices, there is support available for your board (PC87364, from National Semiconductor). Also you may want to install the latest stable version. Per the same website link:

    If your version of sensors-detect failed to detect a chip, you should try the latest version of sensors-detect. sensors-detect is a stand-alone script, so you can simply download it and run it on any system, without installing anything (other than perl). You may also try our Installation Wizard.
    Are you planning to monitor just the fans/board temperatures? For core temperature monitoring you may want to install "coretemp" as well. Once both coretemp and the latest version of lm-sensors are installed, try to run sensors-detect once again.

    Thanks! That be new as my log shows, it detects the sensor but then says it is not available....By the way, the server is running 12.04 LTS (32 bit) and it says my sensor is supported in kernel 2.6.10+, does anyone know what kernel server 12.04 LTS would have?

    Hi,

    Also it looks as if the BIOS doesn't initalise the PC87364 correctly, so I don't think that lm-sensors will work.

    and have a look here:- http://www.coulterfamily.org.uk/page...lm_sensors.php

    Walking on water and writing software to specification is easy if they're frozen.

    Thanks for the info. Would you know how that happens or why it would be the case? It seems to detect the BIOS/PC and sensor just find, and the sensor is listed as supported even on the lm-sensor website as previously linked to....

    That article does also mention the Dell Optiplex GX150 which is the same PC I have so I am confused why this model is so problematic

    Re: lm-sensors issue.

    It looks like almost everything on your board either couldn't be detected or the sensor didn't seem to be returning any information. I would suspect this is a BIOS issue or the board isn't supported by lm-sensors. Is it an older machine? You might have better luck seeing if lm-sensors has a mailing list and posting the output there for the developers to look at.

    Hi,

    Any chance that you can attach a full dmesg from the box. Maybe then I can see where things are going wrong.

    Hey Ian, thanks for the reply. Would you mind explaining how this is done? Did you need the full output? Let me know and I'll get it done, thanks

    12.04 has kernel 3.2.x
