Troubleshooting Nagios Checks
Lab 7.1
The Mariadb check is currently failing in Nagios
To remedy this there are some troubleshooting steps we can take to figure out why
1.
When troubleshooting, start with the simplest thing. In this instance going to the databse server and checking that it's running is the best option to start with
2.
Find the hostgroup to which the check applies
Update the check command in
/etc/nagios4/conf.d/ppt services.cfg
/etc/puppetlabs/code/modules/nagios/manifests
sudo nano config.pp
sudo /opt/puppetlabs/puppet/bin/puppet agent --server=mgmt-a --no-daemonize --verbose --onetime
Restart the Nagios service
sudo systemctl restart nagios4
After completing the lab a new error has emerged concerning the password
To fix this, restart the service
sudo /opt/puppetlabs/bin/puppet agent --test
sudo systemctl restart nagios4.service
