Warnings in munin-graph.log during each graph rendering run

[Thomas Heidrich]

Hi,

I'm using Ubuntu 12.04.2 and noticed that the monitoring tool Munin writes a large amount of warnings into /var/log/munin/munin-graph.log.

[PERL WARNING] Use of uninitialized value $only_fqn in concatenation (.) or string at /usr/share/perl5/Munin/Master/GraphOld.pm line 1361.

I'm currently using 1.4.6-3ubuntu3.3 of the package munin which contains this GraphOld.pm file.

I've debugged the file and confirm the missing initialization. I've compared the file with the 2.0 branch of Munin and backported the change. (see attached patch)

My logs are now clean. Please apply this patch to the next version of the package munin.

Thanks a lot and best regards :-)

I confirm the above patch works. Thanks, Thomas.

The recent update of Munin (Ubuntu Security Notice USN-2090-1, Munin 1.4.6-3ubuntu3.4) still has this issue, so the patch had to be applied manually (again).
