RHBA-2012:1219 - Bug Fix Advisory

Topic

Updated sysstat packages that fix four bugs are now available for Red Hat
Enterprise Linux 5.

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:

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

of open files on CIFS file systems. This update modifies the underlying code to
output the correct number of open files on CIFS file systems. (BZ#706333)

• Prior to this update, the argument for the "-i" option of the "sar" command

used intervals of quarter seconds instead of seconds. This update modifies the
underlying code to print the output in the chosen time interval. (BZ#725266)

• Prior to this update, the device minor number was limited to 256. As a

consequence, the "-p" option of the "sar" command incorrectly displayed device
names greater than 256 as "nodev" or "dev-[major number]-[minor number]". This
update increases the value of the IOC_MAXNIMOR constant. Now, devices names with
minor numbers greater than 256 are displayed correctly in the "sar" output.
(BZ#801701)

• Prior to this update, both disks and partitions were considered for full

statistics. As a consequence, the "-b" option of the "sar" command could, under
certain circumstances, double the actual value. This update adds a test to check
whether a name is a device or a partition before summing. Now, the output
represents the actual values. (BZ#805635)

All users of sysstat are advised to upgrade to these updated packages, which fix
these bugs.

Solution

to your system have been applied.
