GNOME Bugzilla – Bug 466006
Make CPU History in Ressource tab more like the one displayed in the panel
Last modified: 2012-11-09 20:08:24 UTC
The CPU history in the resource tab is a mess when you have multiples CPUs, since utilization keeps passing from one to another. Maybe it only happens on my core2duo, but when only only one core is at 100%, the curve is ugly. I would prefer to have an utilization like it is in the panel view: 50% per core, it's just nice. Or maybe this can be solved by filling the curves.
screenshot of the ugly curves please.
Created attachment 93556 [details] screenshot I realize that the curve *must* be filled, with one color per cpu. Another solution is to display two separate curves, but I don't like the idea: it's less clear.
Why don't you use different colors ? 1 graph/CPU : takes too much space. 4 core is becoming common, soon 8.
It's better with differents colors, but it's not reflecting the fact that only half the cpu power is used.
I think this is fixed by bug #328101 by having default contrasting colours for the graphs it becomes more obvious. The reason you get 50/50 on the panel applet is most likely because it doesn't have the same granularity of sampling as gnome-system-monitor. Any objections to me closing this bug as a dupe of #328101? for the above stated reason.
Would be easy to display a global virtual CPU instead of 1-curve per core
How about an either/or/all option, for instance I could have each core on display at 50% opacity, then the global cpu as a more opaque line, or visa versa. Not difficult at all, but I'd have to add transparency support to GSM colour picker...
with 8 cores, that would be unreadable, i guess
Add an option to show/hide individual cores?
What do you think of the solution proposed in bug 635939, using a stacked area chart? That would look similar to the system monitor applet, only it would help telling the per-core usage too. See an example screenshot [1] [1] - http://bugzilla-attachments.gnome.org/attachment.cgi?id=175373
Robert: perfect!
Then I am marking this as confirmed. I guess we should make switching between the current and the stacked CPU utilization chart an option in Preferences, defaulting to the current one, but if the Stacked area chart works for most people (people with many cores, people with less cores) we can switch the default later on.
Based on what we have discussed above, I am marking this as a duplicate of bug 635939, the one requesting stacked area charts for the CPU chart. That should get fixed in the next release, I have just added an option to turn stacked area CPU chart on from the preferences. Thanks for the bug report. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find. *** This bug has been marked as a duplicate of bug 635939 ***
