Munin Update Failures
Last modified: August 20, 2019
The Munin cPanel plugin displays information about CPU, Exim, Apache®, MySQL® usage, and other information with the
rrdtool logging system. If Munin fails to update, this document provides the steps to resolve the issue.
To troubleshoot this problem, perform the following steps:
Does Munin run during maintenance
Confirm that the nightly cron maintenance runs and that a crontab entry for Munin exists.
crontab -u munin -l command should return output that resembles the following:
*/5 * * * * /usr/local/cpanel/3rdparty/perl/526/bin/munin-cron
Confirm Munin owns the files
munin:munin owns the files in the
munin:munindoes not own the files in the
/var/log/munindirectory, the service will update the log files, but it will not update the graphs that Munin displays.
To set the correct ownership, run the following commands:
Run Munin manually
To run Munin manually, run the
sudo -u munin munin-cron command.
Check the results
New entries will appear in the
/var/log/munin/munin-update log file with no errors. To update the daily graphs, refresh the Munin interface.
