• Backtesting Service: 2.6 days (223,913 seconds)
• ML Training Service: 2.6 days (223,905 seconds)

Issues and Recommendations

✅ Resolved

1. All 4 service metrics endpoints operational
2. Prometheus scraping all targets successfully
3. Grafana datasources configured and accessible
4. Alert rules loaded (7 groups)
5. Dashboards available (2 active, 12 total files)

⚠️ Minor Observations

1. Dashboard Provisioning: Only 2 dashboards active vs 12+ available files
   • Reason: Dashboard files not in provisioning paths
   • Action: Move dashboard JSON files to provisioning paths or verify folder structure
   • Location: /home/jgrusewski/Work/foxhunt/config/grafana/provisioning/dashboards/dashboards.yml
   • Impact: Low (dashboards can be manually imported)
2. Unused Monitoring Config: Multiple prometheus.yml files exist
   • Active: /home/jgrusewski/Work/foxhunt/config/prometheus/prometheus.yml
   • Unused:
     • monitoring/prometheus/prometheus.yml
     • deployment/monitoring/prometheus.yml
   • Action: Consider consolidating to reduce confusion
   • Impact: Low (no functional impact)
3. Zero Activity Metrics: No trading/backtesting/ML jobs executed yet
   • Expected: System is ready for production use
   • Action: Normal operation will populate metrics
   • Impact: None (expected behavior)

✅ Production Ready

1. Metrics collection: 794 unique metrics
2. Scrape latency: <1ms for all trading services
3. Alert rules: 7 groups configured
4. Retention: 15 days
5. Datasources: 4 configured (Prometheus, PostgreSQL, InfluxDB, ClickHouse)

                     → PostgreSQL (5432)
                     → InfluxDB (8086)
                     → ClickHouse (8123)

Conclusion

Status: ✅ MONITORING STACK PRODUCTION READY

The Prometheus/Grafana monitoring stack is fully operational with all 4 microservices exposing metrics, Prometheus scraping successfully, and Grafana dashboards accessible. The system is collecting 794 unique metrics across 6 targets with sub-millisecond scrape latency for trading services.

Key Achievements:

• ✅ 100% target health (6/6 up)
• ✅ Sub-millisecond scrape latency (<1ms for trading services)
• ✅ 794 unique metrics collected
• ✅ 7 alert rule groups configured
• ✅ 4 datasources operational (Prometheus, PostgreSQL, InfluxDB, ClickHouse)
• ✅ 2 dashboards active, 12+ available for provisioning

Production Readiness: READY FOR LIVE TRADING

Next Steps:

1. ✅ Monitoring stack validated - No action required
2. 🔄 Optional: Provision remaining dashboards to Grafana folders
3. 🔄 Optional: Consolidate duplicate prometheus.yml files
4. 📊 Monitor: System will populate activity metrics during normal trading operations
