Description Martin Häcker 2012-11-20 06:57:16 EST
Description of problem: When viewing the virt-manager gui's machine info page and the performance overview on that it does show statistics of the host system for memory and cpu load. This is not what I as a user expect when viewing that data at that place as the GUI strongly suggests that this is data about that selected VM. Version-Release number of selected component (if applicable): How reproducible: 1. Open a Machine 2. go to the Details tab 3. select the Performance entry from the sidebar on the left 4. look at the data Actual results: Shows data from the host system Expected results: Should show data about / from the guest system Additional info: Took me about half a year to figure that out while casually glancing at this screen now and then to understand how my vms are doing. All the while I missed a serious out of memory situation on one of our vms due to this missunderstanding - that would have been very easy to spot had the info been what I expected it to be.
Comment 1 Tadej Janež 2013-04-22 08:29:34 EDT
Agreed, fixing this would be a very nice enhancement to virt-manager.
Comment 2 Cole Robinson 2013-04-29 12:51:50 EDT
Applied Tadej's patch upstream. However in response to comment 1, those graphs still don't show memory usage from inside the guest, that's a more involved fix which requires using newer libvirt APIs. Moving this bug to the upstream tracker for that bit.
Comment 3 Cole Robinson 2014-01-14 16:08:47 EST
True memory usage graphing is upstream now
Comment 4 Martin Häcker 2014-01-15 04:06:24 EST
Thats great! :-)
