From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041012 Firefox/0.10.1 Description of problem: gnome-system-monitor reports the wrong values for "Used memory: xMB of xMB" on the resource monitor tab. see attached screen capture which shows gnome-system-monitor in the foreground and top behind it to demonstrate that the memory used/unused values are clearly wrong. Version-Release number of selected component (if applicable): gnome-system-monitor-2.7.0-2 How reproducible: Always Steps to Reproduce: 1. Run gnome-system-monitor and compare the "used memory" values to TOP 2. 3. Actual Results: used memory is wrong Expected Results: used memory should reflect reality. Additional info:
Created attachment 106091 [details] screenshot showing wrong memory values
gnome-system-monitor is correct in that it doesn't include the buffers/cache memory. This memory is not really used (read: occupied) in the normal way, but is just used temporarily by Linux to increase performance, because else it would be completely unused. In output of "top", subtract the amount of memory listed in the columns "buffers" and "cached". Compare with what the "free" command displays as "used" in the second line. With the usual 1000 KB = 1 MB => 1024 KiB = 1 MiB conversions, the values are equal.
True, but I believe top's value is more useful, because the point where top reports memory as 'all used' is the point where performance starts to degrade.
Fedora Core 3 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thank you!
okay. closing. In FC5 the label is "user memory" for system monitor. This does not directly coorelate to `top` which simply says "used"
thanks!
