RHBA-2010:0552 - Bug Fix Advisory

Topic

An updated sysstat package that provides several bug fixes and adds an
enhancement is now available.

Description

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

This updated sysstat package provide fixes for the following bugs:

• sar data set the maximum number of days in log files too high, which appended

data from the previous month to the next one instead of replacing it. This
updated package resolves this issue and sets the maximum to 25 days. (BZ#609819)

• sysstat's programs such as mpstat wrongly interpreted the /proc data and

showed information about one fictive cpu. This update resolves this issue and
these fictive data are not displayed anymore. (BZ#609821)

• the "sar -d " command used to output invalid data. This issue is resolved and

the updated package recognizes disk reregistration and disk statistic overflow
better. Now, only relevant data is displayed. (BZ#609824)

• on ia64 machines, the output of sar -I ALL/XALL wrongly showed information

about interruptions. This issue is resolved and the updated package does not use
sar -I for this type of architecture. (BZ#609826)

• iostat -n used invalid data to create the statistic. The updated package

resolves this issue and the data source is now changed. Additionally, one new
column has been added. (BZ#609991)

• though function write() executed successful, the return value wasn't equal to

the supposed write size. So, p_write_error() ran and the following message
appeared: "Cannot write data to system activity file: Success". In this updated
package, the sadc utility successfully writes the remaining input, thus
resolving this issue. (BZ#609994)

All sysstat users are advised to upgrade to this updated package, which resolves
these issues.
