Malin bc9f96cbd4 feat: rebrand Hemmelig to paste.es for cloudhost.es

- Set Spanish as default language with ephemeral/encrypted privacy focus
- Translate all user-facing strings and legal pages to Spanish
- Replace Norwegian flag with Spanish flag in footer
- Remove Hemmelig/terces.cloud links, add cloudhost.es sponsorship
- Rewrite PrivacyPage: zero data collection, ephemeral design emphasis
- Rewrite TermsPage: Spanish law, RGPD, paste.es/CloudHost.es references
- Update PWA manifest, HTML meta tags, package.json branding
- Rename webhook headers to X-Paste-Event / X-Paste-Signature
- Update API docs title and contact to paste.es / cloudhost.es

Prometheus Metrics

Hemmelig provides a Prometheus-compatible metrics endpoint for monitoring your instance.

Enabling Metrics

Go to Dashboard > Instance > Metrics tab
Enable the Enable Prometheus Metrics toggle
Optionally, set a Metrics Secret for authentication
Save the settings

Endpoint

GET /api/metrics

Authentication

If a metrics secret is configured, you must include it as a Bearer token in the Authorization header:

curl -H "Authorization: Bearer YOUR_METRICS_SECRET" https://your-instance.com/api/metrics

If no secret is configured, the endpoint is accessible without authentication (not recommended for production).

Available Metrics

Application Metrics

Metric	Type	Description
`hemmelig_secrets_active_count`	Gauge	Current number of active (unexpired) secrets
`hemmelig_users_total`	Gauge	Total number of registered users
`hemmelig_visitors_unique_30d`	Gauge	Unique visitors in the last 30 days
`hemmelig_visitors_views_30d`	Gauge	Total page views in the last 30 days
`hemmelig_http_request_duration_seconds`	Histogram	Duration of HTTP requests in seconds

Default Node.js Metrics

The endpoint also exposes default Node.js runtime metrics including:

nodejs_heap_size_total_bytes - Process heap size
nodejs_heap_size_used_bytes - Process heap size used
nodejs_external_memory_bytes - Node.js external memory
nodejs_eventloop_lag_seconds - Event loop lag
nodejs_active_handles_total - Number of active handles
nodejs_active_requests_total - Number of active requests
process_cpu_user_seconds_total - User CPU time spent
process_cpu_system_seconds_total - System CPU time spent
process_start_time_seconds - Process start time
process_resident_memory_bytes - Resident memory size

Prometheus Configuration

Add the following job to your prometheus.yml:

scrape_configs:
    - job_name: 'hemmelig'
      scrape_interval: 30s
      static_configs:
          - targets: ['your-instance.com']
      metrics_path: '/api/metrics'
      scheme: https
      # If using authentication:
      authorization:
          type: Bearer
          credentials: 'YOUR_METRICS_SECRET'

Grafana Dashboard

You can create a Grafana dashboard to visualize these metrics. Here's an example panel query for active secrets:

hemmelig_secrets_active_count

Security Considerations

Always use a strong, randomly generated secret for the metrics endpoint in production
Consider using network-level restrictions (firewall, VPN) to limit access to the metrics endpoint
The metrics endpoint does not expose any sensitive data (secret contents, user data, etc.)
