Hi! Suddenly, Munin stopped recording data and graphs, so I tried the known solution: uninstall it and reinstall it again. But it didnt work.

I need some command to force reinstall and download all the needed components in case something have been screwed in the disk.

Any help please? Thanks in advance!

I pasted the logs below:

Regarding uninstalling:
Code:
/usr/local/cpanel/scripts/check_cpanel_rpms --fix --targets=munin

And this is whats outputted when installing Munin:

Hi! I made it work. Just deleted the "munin" group+user, located all files saying "munin" something and killed them, forced reinstall of cpanel, install munin, and voila. It's happily working now.

Hello,

I am happy to see the issue is now resolved. Note that reinstalling cPanel is not advised (I assume you may have forced an "update" of cPanel).

Thank you.
