5.140.1. RHBA-2012:0864 — latencytop bug fix and enhancement update

Updated latencytop packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.
LatencyTOP is a tool to monitor system latencies.

Bug Fix

BZ#633698
When running LatencyTOP as a normal user, LatencyTOP attempted and failed to mount the debug file system. A misleading error message was displayed, suggesting that kernel-debug be installed even though this was already the running kernel. LatencyTOP has been improved to exit and display "Permission denied" when run as a normal user. In addition, fsync view has been removed from the "latencytop" package because it depended on a non-standard kernel tracer that was never present in Red Hat Enterprise Linux kernels or upstream kernels. As a result, LatencyTOP no longer attempts to mount the debugfs file system.

Enhancement

BZ#726476
The "latencytop" package requires GTK libraries. Having GTK libraries installed on servers may be undesirable. A build of LatencyTOP without dependencies on GTK libraries is now available under the package name "latencytop-tui".
Users are advised to upgrade to these updated latencytop packages, which fix this bug and add this enhancement.
