Uninstall Observium Ubuntu May 2026

sudo systemctl stop observium_discovery.timer observium_discovery.service sudo systemctl stop observium_poller.timer observium_poller.service If you are using cron jobs instead of systemd timers (common in older installations), you don’t need to stop services—just disable the cron entries later.

Observium is a powerful, auto-discovering network monitoring platform. However, there may come a time when you need to migrate to a different solution (like LibreNMS, Zabbix, or PRTG), free up system resources, or perform a clean reinstallation. Simply deleting the Observium directory is not enough. A proper uninstall involves removing the web files, databases, cron jobs, web server configuration, and the associated system user. uninstall observium ubuntu

dpkg -l | grep php | grep -E "mysql|snmp|gd|curl|mcrypt" If your server runs other PHP applications (e.g., WordPress, Nextcloud), do not purge PHP modules. Only remove the Observium-specific packages if not shared. Step 9: Remove RRDtool and SNMP Tools (If Exclusive to Observium) RRDtool and SNMP tools are heavy dependencies. If you installed them solely for Observium, you can remove them: sudo systemctl stop observium_discovery

sudo nginx -t sudo systemctl reload nginx Observium typically adds a cron job to run the poller and discovery process every 5 minutes or hour. If you were using cron (not systemd), delete the associated file. Simply deleting the Observium directory is not enough

sudo systemctl status observium_discovery.timer If you want a permanent removal, disable and remove the timer units so they don’t resurrect after a reboot.
