   - Uptime (30-day SLA tracking)
   - Request rate and error rate
   - Latency percentiles (p50, p95, p99)
   - Active scenarios counter
   - Infrastructure health

2. **Database Dashboard**
   - Connection usage and limits
   - Query performance metrics
   - Cache hit ratio
   - Slow query analysis
   - Table bloat monitoring

#### Alerting Rules (15+ Rules)

**Critical Alerts:**
- ServiceDown - Backend unavailable
- ServiceUnhealthy - Health check failures
- HighErrorRate - Error rate > 1%
- High5xxRate - >10 5xx errors/minute
- PostgreSQLDown - Database unavailable
- RedisDown - Cache unavailable
- CriticalCPUUsage - CPU > 95%
- CriticalMemoryUsage - Memory > 95%
- CriticalDiskUsage - Disk > 90%

**Warning Alerts:**
- HighLatencyP95 - Response time > 500ms
- HighLatencyP50 - Response time > 200ms
- HighCPUUsage - CPU > 80%
- HighMemoryUsage - Memory > 85%
- HighDiskUsage - Disk > 80%
- PostgreSQLHighConnections - Connection pool near limit
- RedisHighMemoryUsage - Cache memory > 85%

**Business Metrics:**

- IngestionBacklog - Queue depth > 1000

#### Alert Routing (Alertmanager)

**Channels:**
- **PagerDuty** - Critical alerts (immediate)
- **Slack** - Warning alerts (#alerts channel)
- **Email** - All alerts (ops@mockupaws.com)
- **Database Team** - DB-specific alerts

**Routing Logic:**
- Critical → PagerDuty + Slack + Email
- Warning → Slack + Email
