RHBA-2011:1493 - Bug Fix Advisory

Topic

An updated mrtg package that fixes two bugs is now available for Red Hat
Enterprise Linux 5.

Description

The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on
network-links. MRTG generates HTML pages containing Portable Network Graphics
(PNG) images, which provide a live, visual representation of this traffic.

This updated package fixes the following bugs:

• Previously, changing the "kMG" keyword in the MRTG configuration could cause

the labels on the y-axis to overlap the main area of the generated chart. With
this update, an upstream patch has been applied to address this issue, and
changing the "kMG" keyword in the configuration no longer leads to the incorrect
rendering of the resulting charts. (BZ#436662)

• Previously, the package incorrectly informed rpm/yum that it provides

perl(SNMP_util), perl(SNMP_Session), perl(BER) and a few other capabilities.
Because of that, rpm/yum preferred mrtg as a source for those capabilities over
the real source (e.g. perl-SNMP_Session). This caused other packages that expect
to receive perl-SNMP_Session to fail. This updated mrtg package does not state
that it provides those capabilities and as a result rpm/yum will no longer
incorrectly prefer it for those capabilities. (BZ#563619)

Users of mrtg should upgrade to this updated package, which resolves these
issues.

Solution

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