What We Monitor
Key performance indicators we track:
- Page Load Time - Time to interactive
- API Response Time - P50, P95, P99 latencies
- Database Query Time - Slow query detection
- Error Rate - Errors per minute
- Memory Usage - Node.js heap monitoring
Our Stack
- Custom Metrics - Tracked in error_logs table
- Console Monitoring - Structured logging
- Admin Dashboard - Real-time metrics display
Performance Budget
We set targets and alert when exceeded:
- Dashboard load: < 1s
- API endpoints: < 200ms P95
- Database queries: < 100ms
Optimization Workflow
- Monitor metrics continuously
- Alert on threshold breaches
- Profile to identify bottlenecks
- Implement fixes
- Verify improvement
Recent Wins
By adding database indexes and optimizing Prisma queries, we reduced average API response time from 450ms to 120ms.
