For Main Session (Rick):
The project health monitoring system is fully operational and ready for production use.
Key Points:
/home/app/dashboard/data/health-status.jsonTo Monitor:
# View health status
curl http://localhost:3000/api/health/status | jq '.'
# Check auto-refresh logs
pm2 logs dashboard | grep "Health Check"
# View dashboard
open http://localhost:3000/
To Disable Auto-Refresh (if needed):
Comment out startAutoHealthCheck() in /home/app/dashboard/backend/index.js and restart:
pm2 restart dashboard
