      labels:
        service: 'whisperx'
        queue: 'transcription'

- job_name: 'rq-faster-whisper'
  static_configs:
    - targets: ['rq-exporter-faster-whisper:9726']

📈 Performance Benchmarks

🔒 Security

SSL/TLS

• All public services use Let's Encrypt certificates
• Certificate expires: 2026-01-18
• Auto-renewal configured via certbot

Authentication

• Dashy: Basic auth (server credentials)
• Grafana: Basic auth + Grafana login
• RQ Dashboard: Basic auth
• MkDocs: Public (documentation)
• API Endpoints: No auth (internal network)

Recommendations

• Consider adding API key authentication for transcription endpoints
• Implement rate limiting on public endpoints
• Regular security updates for all Docker images

📝 Next Steps & Recommendations

Immediate

12. Create runbooks for common issues

Long-term

1. Load Balancing:
2. Deploy multiple workers per queue
3. Implement job prioritization

4. Add worker auto-scaling based on queue length

5. Backup & Disaster Recovery:

6. Automated backups of Grafana dashboards
7. Redis persistence configuration

8. Documentation backup to git repository

9. Observability:

10. Add application-level metrics (processing time, file sizes)
11. Implement distributed tracing (OpenTelemetry)
12. Create SLO/SLI dashboards
