Monitoring Stack Components

Prometheus Metrics Collection

• Application metrics (latency, errors, throughput)
• Infrastructure metrics (CPU, memory, disk)
• Database metrics (connections, queries, replication)
• Redis metrics (memory, hit rate, connections)
• Container metrics via cAdvisor
• Blackbox monitoring (uptime checks)

Grafana Dashboards

1. Overview Dashboard

   • 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:

• LowScenarioCreationRate - Unusual drop in usage
• HighReportGenerationFailures - Report failures > 10%
• 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
• Info → Email (business hours only)
• Auto-resolve notifications enabled
