Uninstall Observium Ubuntu May 2026

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

# 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

If you installed Observium-specific packages like rrdtool, snmpd, fping, and you no longer need them: uninstall observium ubuntu

sudo apt remove --purge snmpd rrdtool fping mysql-server apache2 php*
sudo apt autoremove --purge

Be cautious — this may remove other services if they share dependencies. First, stop the web server and the poller

After removing Observium, some dependencies might still be installed on your system. To remove them, run: If you installed Observium-specific packages like rrdtool ,

sudo apt-get autoremove

This command will remove any unused dependencies.

Observium relies heavily on cron jobs for polling and discovery. You must remove these, or your system logs will fill up with "file not found" errors.

sudo rm -rf /opt/observium/rrd

If RRDs are stored elsewhere (check config.php), remove that location:

sudo rm -rf /var/lib/observium/rrd
