Before deleting files, stop any active processes to ensure a clean removal.
Stop the Web Server: Depending on your setup, stop either Apache or Nginx. For Apache: sudo systemctl stop apache2. For Nginx: sudo systemctl stop nginx.
Stop the Database: Stop MariaDB or MySQL to prevent further data writing. sudo systemctl stop mariadb or sudo systemctl stop mysql. 2. Remove Scheduled Tasks (Cron Jobs) uninstall observium ubuntu

Method 2: Uninstall Observium from Source
If you installed Observium from source, the uninstallation process is slightly different.
Special cases
- Multi-instance or clustered setups: repeat removal for each node; check centralized DB and external storage locations.
- Remote poller installations: remove poller-specific files and systemd services on poller hosts.
- SNMP daemons: Observium does not require a dedicated SNMP daemon besides snmpd for local monitoring; only remove snmpd if you do not need it for other services.
Step 2: Remove Observium Packages
Now, remove the Observium packages using the following command:
sudo apt-get purge observium
This command will remove the Observium packages, configuration files, and dependencies. Replace <password> with your MySQL root password
