Monitor your devices with LibreNMS on FreeBSD
a day ago
- LibreNMS is a lightweight monitoring alternative to Zabbix, handling SNMP devices with alerts, data, and graphs.
- The installation guide targets FreeBSD 15.0-RELEASE using packages (nginx, php-fpm, MySQL 8.4) without HTTPS or reverse proxy.
- MySQL requires `innodb_file_per_table=1` and `lower_case_table_names=0` before first start.
- php-fpm is configured to use a Unix socket owned by www, and nginx serves LibreNMS from `/usr/local/www/librenms/html`.
- The LibreNMS package on FreeBSD includes sane permissions; only the `.env` file needs manual editing for database credentials and the `INSTALL=true` flag.
- After the web installer completes, the `INSTALL=true` line must be removed from `.env` for security.
- A dedicated rc service (`librenms`) runs the polling dispatcher, eliminating the need for cron entries.
- Validation via `validate.php` may show transient scheduler warnings that resolve after the dispatcher settles.
