Similar bug was opened for RHEL 7. This one contains the patch for the previous Gnome from RHEL 6 Reference on RHEL 7 https://bugzilla.redhat.com/show_bug.cgi?id=1254332 As the patch is already written, this is a very easy fix. While testing a multi-core machine with gnome-system-monitor-2.28.0-13.el6, I was able to see the correct amount of cores listed, as well as the idle cores at 0.0%. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://rhn.redhat.com/errata/RHBA-2017-0578.html |
Created attachment 1064025 [details] Patch for RHEL 6 Gnome glibtop not provides the number of cpus on the machine directly, relying on a list with the current load of each core. Original code assume that a 0 load core is the end of cpu list, which is invalid in cases of machines with high number of cores, that happens to some cores stay idle with 0 load. Since this can happens in any core number, if a machine has 192 cores, but the core number 5 has 0 load, then 4 cores will be wrongly reported. Using standard sysconf api solves the issue in a simple way.
