B.91. sysstat

An updated sysstat package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
The sysstat package provides the sar and iostat commands. These commands enable system monitoring of disk, network, and other I/O activity.
Bug Fix
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.
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.
All users of sysstat are advised to upgrade to this updated package, which resolves these issues.
