+# V2 Docker Monitoring Stack
+
+## Übersicht
+
+Die Monitoring-Lösung für V2 Docker basiert auf dem Prometheus-Stack und bietet umfassende Einblicke in die Performance und Gesundheit aller Services.
+
+## Komponenten
+
+### 1. **Prometheus** (Port 9090)
+- Zentrale Metrik-Sammlung
+- Konfigurierte Scrape-Jobs für alle Services
+- 30 Tage Datenaufbewahrung
+- Alert-Rules für kritische Ereignisse
+
+### 2. **Grafana** (Port 3000)
+- Visualisierung der Metriken
+- Vorkonfigurierte Dashboards
+- Alerting-Integration
+- Standard-Login: admin/admin (beim ersten Login ändern)
+
+### 3. **Alertmanager** (Port 9093)
+- Alert-Routing und -Gruppierung
+- Email-Benachrichtigungen
+- Webhook-Integration
+- Alert-Silencing und -Inhibition
+
+### 4. **Exporters**
+- **PostgreSQL Exporter**: Datenbank-Metriken
+- **Redis Exporter**: Cache-Metriken
+- **Node Exporter**: System-Metriken
+- **Nginx Exporter**: Proxy-Metriken
+
+## Installation
+
+### 1. Monitoring-Stack starten
+
+```bash
+cd monitoring
+docker-compose -f docker-compose.monitoring.yml up -d
+```
+
+### 2. Services überprüfen
+
+```bash
+docker-compose -f docker-compose.monitoring.yml ps
+```
+
+### 3. Grafana-Zugang
+
+1. Öffnen Sie https://monitoring.v2-docker.com (oder http://localhost:3000)
+2. Login mit admin/admin
+3. Neues Passwort setzen
+4. Dashboard "License Server Overview" öffnen
+
+## Konfiguration
+
+### Environment-Variablen
+
+Erstellen Sie eine `.env` Datei im monitoring-Verzeichnis:
+
+```env
+# Grafana
+GRAFANA_USER=admin
+GRAFANA_PASSWORD=secure-password
+
+# PostgreSQL Connection
+POSTGRES_PASSWORD=your-postgres-password
+
+# Alertmanager SMTP
+SMTP_USERNAME=alerts@yourdomain.com
+SMTP_PASSWORD=smtp-password
+
+# Webhook URLs
+WEBHOOK_CRITICAL=https://your-webhook-url/critical
+WEBHOOK_SECURITY=https://your-webhook-url/security
+```
+
+### Alert-Konfiguration
+
+Alerts sind in `prometheus/rules/license-server-alerts.yml` definiert:
+
+- **HighLicenseValidationErrorRate**: Fehlerrate > 5%
+- **PossibleLicenseAbuse**: Verdächtige Aktivitäten
+- **LicenseServerDown**: Service nicht erreichbar
+- **HighLicenseValidationLatency**: Antwortzeit > 500ms
+- **DatabaseConnectionPoolExhausted**: DB-Verbindungen > 90%
+
+### Neue Alerts hinzufügen
+
+1. Editieren Sie `prometheus/rules/license-server-alerts.yml`
+2. Fügen Sie neue Alert-Regel hinzu:
+
+```yaml
+- alert: YourAlertName
+  expr: your_prometheus_query > threshold
+  for: 5m
+  labels:
+    severity: warning
+    service: your-service
+  annotations:
+    summary: "Alert summary"
+    description: "Detailed description"
+```
+
+3. Prometheus neu laden:
+
+```bash
+curl -X POST http://localhost:9090/-/reload
+```
+
+## Dashboards
+
+### License Server Overview
+
+Zeigt wichtige Metriken:
+- Aktive Lizenzen
+- Validierungen pro Sekunde
+- Fehlerrate
+- Response Time Percentiles
+- Anomalie-Erkennung
+- Top 10 aktivste Lizenzen
+
+### Neue Dashboards erstellen
+
+1. In Grafana einloggen
+2. Create → Dashboard
+3. Panel hinzufügen
+4. Prometheus-Query eingeben
+5. Dashboard speichern
+6. Export als JSON für Backup
+
+## Metriken
+
+### License Server Metriken
+
+- `license_validation_total`: Anzahl der Validierungen
+- `license_validation_duration_seconds`: Validierungs-Dauer
+- `active_licenses_total`: Aktive Lizenzen
+- `anomaly_detections_total`: Erkannte Anomalien
+
+### System Metriken
+
+- `node_cpu_seconds_total`: CPU-Auslastung
+- `node_memory_MemAvailable_bytes`: Verfügbarer Speicher
+- `node_filesystem_avail_bytes`: Verfügbarer Festplattenspeicher
+
+### Datenbank Metriken
+
+- `pg_stat_database_numbackends`: Aktive DB-Verbindungen
+- `pg_stat_database_tup_fetched`: Abgerufene Tupel
+- `pg_stat_database_conflicts`: Konflikte
+
+## Troubleshooting
+
+### Prometheus erreicht Service nicht
+
+1. Netzwerk überprüfen:
+```bash
+docker network inspect v2_internal_net
+```
+
+2. Service-Discovery testen:
+```bash
+docker exec prometheus wget -O- http://license-server:8443/metrics
+```
+
+### Keine Daten in Grafana
+
+1. Datasource überprüfen:
+   - Settings → Data Sources → Prometheus
+   - Test Connection
+
+2. Prometheus Targets checken:
+   - http://localhost:9090/targets
+   - Alle Targets sollten "UP" sein
+
+### Alerts werden nicht gesendet
+
+1. Alertmanager Logs prüfen:
+```bash
+docker logs alertmanager
+```
+
+2. SMTP-Konfiguration verifizieren
+3. Webhook-URLs testen
+
+## Wartung
+
+### Backup
+
+1. Prometheus-Daten:
+```bash
+docker exec prometheus tar czf /prometheus/backup.tar.gz /prometheus
+docker cp prometheus:/prometheus/backup.tar.gz ./backups/
+```
+
+2. Grafana-Dashboards:
+   - Export über UI als JSON
+   - Speichern in `grafana/dashboards/`
+
+### Updates
+
+1. Images updaten:
+```bash
+docker-compose -f docker-compose.monitoring.yml pull
+docker-compose -f docker-compose.monitoring.yml up -d
+```
+
+2. Konfiguration neu laden:
+```bash
+# Prometheus
+curl -X POST http://localhost:9090/-/reload
+
+# Alertmanager
+curl -X POST http://localhost:9093/-/reload
+```
+
+## Performance-Optimierung
+
+### Retention anpassen
+
+In `docker-compose.monitoring.yml`:
+```yaml
+command:
+  - '--storage.tsdb.retention.time=15d'  # Reduzieren für weniger Speicher
+```
+
+### Scrape-Intervalle
+
+In `prometheus/prometheus.yml`:
+```yaml
+global:
+  scrape_interval: 30s  # Erhöhen für weniger Last
+```
+
+### Resource Limits
+
+Passen Sie die Limits in `docker-compose.monitoring.yml` an Ihre Umgebung an.
+
+## Sicherheit
+
+1. **Grafana**: Ändern Sie das Standard-Passwort sofort
+2. **Prometheus**: Kein öffentlicher Zugriff (nur intern)
+3. **Alertmanager**: Webhook-URLs geheim halten
+4. **Exporters**: Nur im internen Netzwerk erreichbar
+
+## Integration
+
+### In CI/CD Pipeline
+
+```bash
+# Deployment-Metriken senden
+curl -X POST http://prometheus-pushgateway:9091/metrics/job/deployment \
+  -d 'deployment_status{version="1.2.3",environment="production"} 1'
+```
+
+### Custom Metriken
+
+In Ihrer Anwendung:
+```python
+from prometheus_client import Counter, Histogram
+
+custom_metric = Counter('my_custom_total', 'Description')
+custom_metric.inc()
+```
+
+## Support
+
+Bei Problemen:
+1. Logs überprüfen: `docker-compose -f docker-compose.monitoring.yml logs [service]`
+2. Dokumentation: https://prometheus.io/docs/
+3. Grafana Docs: https://grafana.com/docs/
