RHBA-2012:0866 - Bug Fix Advisory

Topic

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

Description

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

This update fixes the following bugs:

• Prior to this update, the cifsiostat utility did not report the correct number

of open files on CIFS file systems. A patch has been applied to ensure that the
cifsiostat utility outputs the correct number of open files on CIFS file
systems. (BZ#690562)

• Prior to this update, the "iostat -n" command did not list NFS shares with

excessively long names. The underlying source code has been revised to ensure
that the command lists all NFS shares available. (BZ#694759)

• Previously, nr_requests could overflow if set to high values. As a

consequence, the "iostat" and "sar -d" command would report the overflowed
values from the /proc/diskstats file instead of the proper values. The
underlying source code has been modified to ensure that the "iostat" and "sar

• d" commands output the correct information. (BZ#771594)
• Previously, the sa2 script could return an error code even when the script

completed successfully. The underlying source code has been modified so that the
sa2 script now returns the correct code on successful completion. (BZ#801453)

• Running the "sar" command with the "-p" option to "pretty-print" device names

did not work as expected if the device minor number was greater than 256. The
device names were incorrectly displayed as "nodev" or "dev-[major number]-[minor
number]". With this update, the value of the IOC_MAXNIMOR constant has been
increased, and devices with the minor number greater than 256 are now displayed
correctly in the "sar" output. (BZ#801702)

This update also adds the following enhancements:

• Previously, on 64-bit PowerPC architectures, the mpstat utility displayed all

processors, including both busy and idle processors with zero activity. This
update introduces a new option for the mpstat utility, "-P ON". If this option
is used, mpstat lists only online processors. (BZ#674648)

• With this update, the SADC_OPTIONS configuration variable has been moved from

the sysstat init script, located in the /etc/init.d/ directory, to the sysstat
configuration file located in the /etc/sysconfig/ directory. Also, a note about
the -S option was added to the sadc manual page. (BZ#693398)

• Previously, the iostat utility did not display target device information if a

symbolic link was specified as an input parameter. This update adds support for
symbolic links as input parameters in the iostat utility. (BZ#766431)

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