Uninstall Observium Ubuntu -

That’s fine. Just move to the next step.

Observium uses MySQL or MariaDB. The default database name is observium. Dropping the database is the most critical step in removing all monitoring data.

First, log into your database:

sudo mysql -u root -p

Then, execute the following SQL commands:

DROP DATABASE IF EXISTS observium;
DROP USER IF EXISTS 'observium'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Note: If you used a different username (e.g., observium_user) or a remote host, adjust the DROP USER command accordingly. uninstall observium ubuntu

Double-check removal:

sudo mysql -u root -p -e "SHOW DATABASES;" | grep observium

(You should see no output.)

sudo apt-get autoremove --purge
sudo apt-get autoclean

This guide will help you completely remove Observium and its associated components from an Ubuntu system.

First, stop the web server and the poller services to prevent data corruption or processes interfering with the removal. That’s fine

# Stop Apache (or Nginx if you used that)
sudo systemctl stop apache2
sudo systemctl disable apache2
# Stop the Observium poller service (if configured as a systemd service)
sudo systemctl stop observium
sudo systemctl disable observium

Before deleting files, stop the web server service to ensure no active processes are holding onto the Observium files.

sudo systemctl stop apache2

If you had set up any specific Observium system services (rare, but possible), disable those as well. Then, execute the following SQL commands: DROP DATABASE

sudo rm -f /etc/nginx/sites-available/observium
sudo rm -f /etc/nginx/sites-enabled/observium
sudo systemctl reload nginx
