[Bug 680353] Re: "No temperature information is available" although machine does have thermal sensors
So.. what is happening with this? It would be nice to be able to see my temperatures, which sensors is able to do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/680353 Title: "No temperature information is available" although machine does have thermal sensors To manage notifications about this bug go to: https://bugs.launchpad.net/landscape-client/+bug/680353/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

People might also want to graph hdd temperatures? How does that abstraction work? Can it tell what each tempN above is? If yes, any particular reason why sensors doesn't use it? But I think 'sensors' does use libsensors. At any rate its package lm-sensors does depend on libsensors, and it can for example show hdd temperatures. I haven't looked at the code so I would only be guessing how it works. At least on my machine it doesn't know where the tempN probes are. One of the concerns I have is that the output of sensors is not always accurate and can be confusing, with names we have no idea what they represent, like temp1, temp2, etc. I agree, though this does seem to be a problem for acpi too? Not in our experience, the thermal zones from acpi have been correct so far both in values and in which component is being measured. I seem to recall just often seeing numbered zones in acpi, but you've probably seen more different machines for this than I have. Another problem, across all methods, is that some sensors seem stuck at unreasonable values like 0 or 127C. Yes. Unfortunately that coincides with the maximum possible value for an 8 bit value, right? In a way that's fortunate because you can easily conclude it's not a real value. If I was going to programmatically reduce it to a single value, I would probably take the maximum plausible value at any moment across all sensors. Or do this per grouping, if we're getting any useful grouping metadata: the hottest probe in the drives is currently: 46C; the hottest probe in the cpu is 48C; etc. Yeah, but sensors doesn't tell us which temp is cpu, which temp is hard drive, etc. Unless the abstraction you mentioned above does. When I run 'sensors' on my laptop, it does seem to include hdd temperatures, labelled as such. (Or maybe it's the motherboard sensor next to the hdd.) I guess for drives what would be good is to run hddtemp; that could be a separate bug: m...@grace% sudo hddtemp /dev/sd? /dev/sda: ST31000528AS: 39°C /dev/sdb: WDC WD10EACS-00ZJB0: 44°C /dev/sdc: WDC WD10EACS-00D6B0: 47°C /dev/sdd: WDC WD5000AAKS-22TMA0: 46°C /dev/sde: WDC WD5000AAKS-22TMA0: 45°C /dev/sdf: Generic Flash HS-CF: S.M.A.R.T. not available /dev/sdg: Generic Flash HS-COMBO: S.M.A.R.T. not available -- Martin -- No temperature information is available although machine does have thermal sensors https://bugs.launchpad.net/bugs/680353 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 680353] Re: No temperature information is available although machine does have thermal sensors
This happens because we use acpi to get the thermal data, and this seems to work only for laptops. A workaround is to use a custom graph to plot the desired output of the sensors command. Here is an example: https://help.landscape.canonical.com/CustomGraphs/Examples#lm-sensors That being said, we could probably fallback to lm-sensors if there is no temperature being reported by acpi. One of the concerns I have is that the output of sensors is not always accurate and can be confusing, with names we have no idea what they represent, like temp1, temp2, etc. In my laptop, for example, I have 16 values for temp alone when using the ISA adapter, and two values for the Virtual Device adapter. I have no idea how we could decide programatically which values to use in the graph. What I usually do is pick the one that looks more reasonable, or agrees with what I see in the computer BIOS, and stick to that. ** Also affects: landscape-client Importance: Undecided Status: New ** Changed in: landscape-client Status: New = Confirmed ** Changed in: landscape-client Importance: Undecided = Wishlist -- No temperature information is available although machine does have thermal sensors https://bugs.launchpad.net/bugs/680353 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
