Bug Fix Advisory

Topic

An updated sysstat package that fixes various bugs and adds two enhancements is
now available for Red Hat Enterprise Linux 6.

Description

The sysstat package provides the sar and iostat commands. These commands enable
system monitoring of disk, network, and other I/O activity.

This update fixes the following bugs:

• on a system with a running KVM virtual machine and under very special
  circumstances, the mpstat utility may have produced an output that contained
  incorrect values. This error no longer occurs, and the mpstat utility now always
  produces the correct output. (BZ#595231, BZ#536928)
  
• on a system with a running KVM virtual machine and under very special
  circumstances, the sar utility may have produced an output that contained
  incorrect values. This error no longer occurs, and the sar utility now always
  produces the correct output. (BZ#637705)
  
• due to recent changes in the /proc/interrupts format, running the "mpstat -I
  ALL" command did not produce the correct output. With this update, the mpstat
  utility has been updated to recognize the new format, and running the above
  command now works as expected. (BZ#624130)
  
• previously, the "iostat -n" command was not aware of any NFS shares that were
  mounted or unmounted while processing. Consequently, iostat reported incorrect
  values such as:
  

nfs:/share 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

In this updated package the "iostat -n" command is made aware of any NFS shares
that are mounted or unmounted while the command is running, and reports
meaningful results. (BZ#690402)

• under certain circumstances, the sar tool was unable to accurately report
  system activity on systems with multiple CPUs that also use the tickless kernel.
  If this issue was encountered, sar would report values of 0.00 for all values of
  some CPUs. In this updated package, sar correctly handles the behavior of the
  tickless kernel and returns accurate results. (BZ#631841)
  

As well, this update adds the following enhancements:

• previously, iostat lacked the ability to provide granular I/O statistics for
  Common Internet File System (CIFS) shares. This updated iostat package includes
  the new cifsiostat tool, providing the ability to generate I/O statistics for
  CIFS shares. (BZ#592283)
  
• previously, default parameters could not be set for the sadc command. In this
  updated package, parameters for the "sadc" command can be set using the
  "${SADC_OPTIONS}" variable located in the "/etc/sysconfig/sysstat" configuration
  file (BZ#690400)
  

All users of sysstat are advised to upgrade to this updated package which fixes
these bugs and adds these enhancements.

Solution

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

This update is available via the Red Hat Network. Details on how to
