Uninstall Observium Ubuntu Here

Observium stores all its device, port, and alerting data in a MySQL or MariaDB database. To fully uninstall, you should drop this database.

Replace paths, PHP versions, and names to match your install.

sudo systemctl stop observium sudo systemctl disable observium sudo systemctl stop apache2 php7.4-fpm uninstall observium ubuntu

sudo tar -czf ~/observium-config-backup-$(date +%F).tgz /opt/observium/config.php /opt/observium/rrd /opt/observium/logs sudo mysqldump -u root -p observium > ~/observium-db-backup-$(date +%F).sql

sudo rm -rf /opt/observium /var/www/observium /var/log/observium sudo mysql -u root -p -e "DROP DATABASE IF EXISTS observium; DROP USER IF EXISTS 'observium'@'localhost'; FLUSH PRIVILEGES;" sudo rm /etc/apache2/sites-available/observium.conf /etc/apache2/sites-enabled/observium.conf sudo a2dissite observium.conf || true sudo systemctl reload apache2 Observium stores all its device, port, and alerting

sudo rm /etc/php/7.4/fpm/pool.d/observium.conf sudo systemctl restart php7.4-fpm

sudo rm /etc/cron.d/observium sudo userdel -r observium || true sudo find / -iname 'observium' -maxdepth 4 Replace paths, PHP versions, and names to match your install

Stop the Observium service, remove Observium files (usually /opt/observium or /usr/local/observium), drop the observium MySQL/MariaDB database and user, remove webserver virtual host and PHP config, delete cron jobs and monitoring users, and optionally remove RRDtool/Graphing data and dependencies.

As with the package manager method, stop the Observium services:

sudo service observium-CollectD stop
sudo service observium-Poller stop
sudo service observium-Apache stop

sudo rm -rf /opt/observium

If you installed elsewhere (e.g., /var/www/html/observium):

sudo rm -rf /var/www/html/observium
