Uninstall Observium Ubuntu ((top)) Info

You likely have an Apache or Nginx virtual host pointing to your Observium directory. You should disable and remove this to prevent the web server from throwing errors. Disable the site: sudo a2dissite observium.conf Use code with caution. Restart Apache: sudo systemctl restart apache2 Use code with caution. Delete the configuration file: sudo rm /etc/apache2/sites-available/observium.conf Use code with caution. For Nginx: Remove the symbolic link: sudo rm /etc/nginx/sites-enabled/observium Use code with caution. Restart Nginx: sudo systemctl restart nginx Use code with caution. Remove the site config: sudo rm /etc/nginx/sites-available/observium Use code with caution. Step 3: Drop the MySQL/MariaDB Database

Are you planning to with another monitoring tool like LibreNMS or Zabbix , or are you decommissioning the server entirely?
