validation +- Safe escaping of user-visible text fields +- Reusable static/class methods for field-level and form-level validation + +Intended to be used with Pydantic or similar schema-driven systems to validate and sanitize +user input in a consistent, centralized way. + +Dependencies: +- Standard Library: re, html, logging, urllib.parse +- First-party: `settings` from `mcpgateway.config` +

+| Feature | Internal Observability | OpenTelemetry | +|---------|----------------------|---------------| +| **Storage** | Database (SQLite/PostgreSQL/MariaDB) | External backends (Phoenix, Jaeger, Tempo) | +| **Setup** | Built-in, zero configuration | Requires external services | +| **Cost** | Free, self-hosted | Depends on backend (free OSS or paid SaaS) | +| **Retention** | Configurable in-database | Backend-dependent | +| **UI** | Admin UI dashboards | Backend-specific UIs | +| **Performance Impact** | Minimal (database writes) | Minimal (async exports) | +| **Use Cases** | Development, testing, small deployments | Production, microservices, distributed systems | +| **Standards** | Custom implementation | OpenTelemetry standard | +| **Integration** | Self-contained | Integrates with APM ecosystem | + +### When to Use Each + +**Use Internal Observability when:** + +- You want zero external dependencies +- Database storage is acceptable +- Admin UI visualization is sufficient +- Deployment simplicity is a priority +- You're in development/testing mode + +**Use OpenTelemetry when:** + +- You need distributed tracing across multiple services +- You want vendor-agnostic standard +- You have existing observability infrastructure +- You need advanced APM features +- You're in production with high scale + +**Use Both when:** + +- You want local debugging with external production monitoring +- You need different retention policies +- You want redundancy in observability data + +## Production Considerations + +### Performance Impact + +The internal observability system is designed for minimal overhead: + +- **Database Writes**: Async, batched when possible +- **Indexing**: Optimized indexes for fast queries +- **Sampling**: Reduce load with configurable sample rates +- **Cleanup**: Automatic retention management + +### Scaling Recommendations + +For high-volume deployments: + +```bash +# Reduce sampling rate +OBSERVABILITY_SAMPLE_RATE=0.1 # 10% sampling + +# Aggressive retention +OBSERVABILITY_TRACE_RETENTION_DAYS=3 + +# Exclude high-frequency paths +OBSERVABILITY_EXCLUDE_PATHS=/health.*,/metrics.*,/static/.* + +# Disable HTTP request tracing (manual traces only) +OBSERVABILITY_TRACE_HTTP_REQUESTS=false +``` + +### Database Considerations + +####

**Enable debug logging**: + + ```bash + export LOG_LEVEL=DEBUG + mcpgateway + # Look for observability-related log messages + ``` + +### High Database Size + +1. **Reduce retention period**: + + ```bash + OBSERVABILITY_TRACE_RETENTION_DAYS=3 + ``` + +2. **Lower maximum traces**: + + ```bash + OBSERVABILITY_MAX_TRACES=10000 + ``` + +3. **Increase sampling threshold**: + + ```bash +

shorter time windows (1 hour instead of 30 days) + +2. **Limit result count**: + + - Query top 10 instead of top 100 + +3. **Add database indexes** (if custom deployment): + + ```sql + CREATE INDEX
