I just upgraded to Munin 1.4.3 on Centos 5.4 (from 1.3.x I think) the other day and after some time noticed that my Graphs were not updating.

After a long bout of debugging and cursing Munin’s inability to provide any indications of what was wrong, I suddenly understood my error: I was deeplinking into pages that were not updated anymore because the Munin upgrade changed the way generated files are structured.

The following is the quick fix:

su -s /bin/bash muninfind . -name"*.html"-ls -exec rm -f {} \;/usr/bin/munin-cron

I.e delete all html files generated by munin and ask it to generate them over again _as the munin user_.

I sure hope this helps someone!
