 ## Fix Recenti (Novembre 2025)
 
+### 🐛 Fix Monitoring Syslog Parser + Schema Database (22 Nov 2025 - 11:10)
+- **Problema 1**: Dashboard mostrava Syslog Parser in errore nonostante systemd "active (running)"
+  - **Causa**: Bug fetch `signal: controller2.abort` invece di `signal: controller2.signal` in `/api/services/status`
+  - **Soluzione**: Corretto parametro AbortController signal
+- **Problema 2**: Errore database `column "destination_ip" does not exist`
+  - **Causa**: Database server usa `dest_ip`/`src_ip` invece di `destination_ip`/`source_ip`
+  - **Soluzione**: Migrazione SQL 003 rinomina colonne in formato corretto
+- **Fix Applicati**:
+  - ✅ `server/routes.ts`: Corretto signal in fetch monitoring
+  - ✅ `database-schema/migrations/003_fix_network_logs_columns.sql`: Migrazione rinomina colonne
+- **Deploy**:
+  1. Eseguire `./update_from_git.sh --db` per applicare migrazione
+  2. Riavviare backend Node.js
+  3. Dashboard mostrerà correttamente tutti i servizi (pallini verdi)

 ### 🚨 Database Full - Auto-Cleanup Fix (21 Nov 2025 - 18:00)
 - **Problema**: Database PostgreSQL pieno con **417 MILIONI di log** accumulati
   - Syslog parser ha processato 417.7M righe senza limite di retention
