sysstat bug fix and enhancement update

Bug Fix Advisory

Topic

Updated sysstat packages that fix several bugs and add two enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The sysstat packages provide a set of utilities which enable system monitoring
of disks, network, and other I/O activity.

This update fixes the following bugs:

• When the sysstat utility appended new statistics to the "sa" daily data files,
  it did not check whether those files existed from the previous month. Under
  certain circumstances, for example when a month was short, sysstat appended new
  statistics to the old files. With this update, the utility has been modified to
  check whether the old files exist and remove them in case they does. As a
  result, new statistics are not appended to the old "sa" files. (BZ#921612)
  
• Previously, the "sa2" script did not support the xz compression. As a
  consequence, old daily data files were not deleted. The support for the xz
  compression has been added to the script and the data is now deleted as
  expected. (BZ#1088998)
  
• The dynamic ticks kernel feature can currently make the /proc/stat file
  unreliable because a CPU cannot provide reliable statistics if it is stopped.
  Even though the kernel is trying to provide the best guess, the statistics are
  not always accurate. As a consequence, some sysstat commands could show
  overflowed values. This update detects values going backwards in sysstat, and
  sysstat commands no longer show overflowed values.(BZ#1124180)
  

In addition, this update adds the following enhancements:

• With this update, the user is able to set a compress method in the
  /etc/sysconfig/sysstat configuration file using the ZIP variable. This
  enhancement provides an easier configuration of the data file compression
  method. (BZ#1102603)
  
• The sysstat(5) manual page now provides documentation of the
  /etc/sysconfig/sysstat configuration file as well as detailed description of the
  HISTORY configuration variable. (BZ#1110851)
  

Users of sysstat are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
