Feature changed by: Robert Davies (robopensuse) Feature #302446, revision 40 Title: Power consumption gauge openSUSE-11.0: Rejected by Gary Ekker (gekker) reject date: 2008-05-09 10:28:15 reject reason: Nothing done for 11.0. Priority Requester: Desirable openSUSE-11.1: Rejected by JP Rosevear (jproseve) reject date: 2008-09-10 16:50:33 reject reason: Dependent feature not complete. Priority Requester: Desirable Projectmanager: Important openSUSE-11.2: Rejected by Stephan Kulow (coolo) reject date: 2009-08-12 12:06:48 reject reason: too late for 11.2 Priority Requester: Desirable Projectmanager: Desirable openSUSE-11.3: New Priority Requester: Desirable Requested by: Frank Seidel (fseidel) Description: Some kind of "power meter" would be good to have. It could be integrated into the system monitor applet or in kpowersave/gnome-power- manager (to be discussed). Its intent is to make the user aware when the system starts to hog power (e.g. after starting some bad behaving application that polls "expensive" hardware all the time). Some kind of "power meter" would be good to have. It could be integrated into the system monitor applet or in kpowersave/gnome-power-manager (to be discussed). Relations: - provide common source for a overall battery time information (feature/id: 303749) Documentation Impact: Needs to be documented Discussion: #1: Michael Löffler (michl19) (2008-02-01 11:56:22) In regards of Green IT theme for SLE 11 this sounds like useful thing. #2: Stefan Behlert (sbehlert) (2008-05-29 23:23:48) (reply to #1) Right.. #4: JP Rosevear (jproseve) (2008-06-02 13:52:01) Christian, can we actually aggregate power consumption information from somewhere? If so, getting a gui on top of it should be straight forward. #5: Christian Zoz (zoz) (2008-06-19 15:03:57) Power consumption information is only available when the system runs on battery. But i guess on ac-power this info is less interesting anyway. We can get this information via ACPI. Not really power consumption, but power drain of each battery. I suggest that hal can provide individual drain and aggregate overall power consumption. For that have a look at feature: #303749: provide common source for a overall battery time information #6: Rodrigo Moya (rodrigomoya) (2008-09-08 14:43:35) For gnome-power-manager, we already have something like this (right- click -> power history), it shows lots of information about powe consumption. Isn't this enough? #7: JP Rosevear (jproseve) (2008-09-10 16:49:55) Fate 303749 is not complete, so I think I have to reject this. #9: ali ershad-manesh (gorbehnare) (2009-04-30 07:09:01) I'm not a developer, and I just know a little about computers, however I don't think the computer can measure power consumption in the first place. I don't think the Power Supplies are smart enough or connected enough yet to give that information. At least to the best of my knowledge. On a laptop running on battery some power drain can be calculated to estimate the battery life. On a desktop... I don't think it's going to work. I have a UPS that comes with a monitoring software that shows the power consumption . It runs a little Java based GUI that shows power status. Unfortunately the UPS software only works in Windows and is very hardware specific to this particular UPS. If someone needs these kind of information a UPS with Linux compatible software might just do the trick! #11: Matthias Nagorni (mnagorni) (2009-08-24 12:36:25) It really depends on the user scenario: For a Thin Client type of installation you would probably want to hide this level of system detail, however for notebook usage it appears to be very useful. Therefore "Important" but should be configurable. #13: Klaas Freitag (kfreitag) (2009-08-25 11:58:09) Sorry, we're not working for SLE SPs. + #16: Robert Davies (robopensuse) (2009-11-30 17:35:07) + Could something using wake ups & idle time reporting do most of the + job, and be more generally useful like powertop?  Then actually this is + interesting on some mains systems to, things like virtualised servers, + or with high machine density in data-centre.  Also perhaps on desktop + where poor applications cause noise from cooling fans. -- openSUSE Feature: https://features.opensuse.org/302446
