An updated seekwatcher package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The seekwatcher package generates graphs from blktrace runs to help visualize I/O patterns and performance. It can plot multiple blktrace runs together, making it easy to compare the differences between different benchmark runs.
Prior to this update, an obsolete "matplotlib" configuration directive in seekwatcher caused seekwatcher to emit a spurious warning when executed. This bug has been fixed in this update and no longer occurs.
All users of seekwatcher should upgrade to this updated package, which fixes this bug.
