   - **Critical:** ALWAYS use the `syslog_db_*` wrapper functions (defined in `database.php`) for all database operations. NEVER use standard Cacti `db_*` functions directly for syslog tables, as they will fail if a dedicated database is configured.
 - **Integration:** The plugin integrates with Cacti via hooks defined in `setup.php`.
 - **Poller Integration:** Background processes (`syslog_process.php`, `syslog_removal.php`) are triggered by Cacti's poller or run independently.
+- **Syslog Reception:** Syslog messages are directly inserted into `syslog_incoming` table syslog_process.php then processes them.
