Troubleshooting Munin

For troubleshooting the problem, perform the steps given below:

  1. Make sure that Munin is running during maintenance. Ensure that the nightly cron maintenance is running and that a crontab entry for Munin is existing. The crontab –u munin -1 command ought to return the output that resembles the following syntax

*/5 * * * * /usr/local/cpanel/3rdparty/perl/526/bin/munin-cron

  1. Confirm the ownership- In case munin does not own the files in the specific / var / log / munin directory, the service is bound to update the log files. However, it will not update the graphs that Munin displays.

In order to set the accurate ownerships, run the following commands-

chown -R munin:munin /var/log/munin

chown -R munin:minin /var/lib/munin

  1. Make sure you run the sudo –u munin munin- cron demand for running the Munin manually.
  2. Once you are done performing the aforementioned steps, check the results. New entries ought to appear in the / var / log /munin / munin- update log file with absolutely no errors. In order to update the daily graphs, refresh the Munin interface.

Munin’s graphs that appear on a weekly basis will only display the updates when the user has configured in the crontab menu for Munin.
