RHBA-2010:0099 - Bug Fix Advisory

Topic

Updated libgtop2 packages that resolve an issue are now available.

Description

The libgtop2 package contains a library that enables access to information
related to system statistics such as CPU, memory and disk usage, active
processes, PIDs, and more.

These updated libgtop2 packages fix the following bug:

• stat files live under the /sys/block directory; for example,

/sys/block/sda/sda1/stat would be the stat file corresponding to the first
partition on the first (non-IDE) drive. These stat files provide several
statistics about the state of a block device. However, libgtop2 parsed the
line of information supplied by stat files on recent versions of Red Hat
Enterprise Linux incorrectly, which caused, for example, the GNOME System
Monitor utility to display graphs which used incorrect colors and/or
values. This update ensures that the stat files are parsed correctly and
thus supply correct information to applications which make use of libgtop2.
(BZ#548693)

• libgtop2 was unable to correctly parse /proc/[pid]/smaps files to

determine memory usage information due to the fact that a field for swap
usage was added to smaps files. This update fixes the parser so that it is
once again able to correctly parse smaps files. (BZ#562817)

All users are advised to upgrade to these updated packages, which resolve
this issue.
