RHBA-2012:0864 - latencytop bug fix and enhancement update

Synopsis

latencytop bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated latencytop packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

LatencyTOP is a tool to monitor system latencies.

This update fixes the following bugs:

  • 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. (BZ#633698)

This update also adds the following enhancement:

  • 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". (BZ#726476)

Users are advised to upgrade to these updated latencytop packages, which fix this bug and add this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
