## Post-Deployment Monitoring Plan

### Immediate Monitoring (First 24 Hours)

**Metrics to Watch**:
1. **Service Health**:
   - Check: `docker-compose ps` every 5 minutes
   - Alert: Any service unhealthy
   - Action: Review logs, restart if needed

2. **Performance Latency**:
   - P50 auth latency: Alert if >15μs (target <10μs)
   - P99 auth latency: Alert if >100μs (target <50μs)
   - P99 order matching: Alert if >50μs (target <50μs)

3. **Database Health**:
   - Inserts/sec: Alert if <2,000/sec (target 2,979/sec)
   - Cache hit ratio: Alert if <90% (current 99.97%)
   - Connection pool: Alert if >80% (current 13%)

4. **Error Rates**:
   - JWT validation failures: Alert if >1%
   - Order submission failures: Alert if >0.5%
   - Database rollbacks: Alert if >1% (current 0.09%)

**Prometheus Queries**:
```promql
# Service health
up{job=~"api_gateway|trading_service|backtesting|ml_training"} == 1

# Auth latency (P99)
histogram_quantile(0.99, rate(api_gateway_auth_duration_seconds_bucket[5m]))

# Database inserts/sec
rate(postgres_inserts_total[1m])

# Error rate
rate(api_gateway_errors_total[5m]) / rate(api_gateway_requests_total[5m])
```

**Alert Thresholds**:
- Critical: Response time >100ms, Error rate >1%, Service down
- Warning: Response time >50ms, Error rate >0.5%, Cache hit <90%

### Week 1 Monitoring (Days 1-7)

**Daily Checks**:
1. Review Grafana dashboards (http://localhost:3000)
2. Check Prometheus alert history (http://localhost:9090)
3. Analyze slow query log (if P99 >50μs)
4. Review audit logs for security incidents

**Weekly Report**:
- Total orders processed
- Average/P99 latency
- Error rate
- Uptime (target: 99.9%)
- Performance vs. baseline

### Month 1 Monitoring (Days 1-30)

**Weekly Metrics**:
1. Capacity analysis (CPU, memory, connections)
2. Database growth rate
3. Performance degradation trends
4. Security incident review

**Optimization Opportunities**:
- Identify slow queries (>10ms)
- Review unused indexes
- Analyze cache miss patterns
- Tune connection pool size

### Long-Term Monitoring (Ongoing)

**Monthly Review**:
1. Certificate expiration check (current: Oct 2026)
2. Dependency vulnerability scan (`cargo audit`)
3. Database backup validation
4. Disaster recovery test

**Quarterly Review**:
1. Capacity planning
2. Performance baseline update
3. Security audit
4. Compliance review (SOX, MiFID II)

---

## Rollback Procedures

### Rollback Triggers

**Automatic Rollback** (if observed):
- Service health: Any service down >5 minutes
- Error rate: >5% for >10 minutes
- Latency: P99 >1 second for >5 minutes
- Database: Connection pool exhausted

**Manual Rollback** (judgment call):
- Security incident detected
- Data corruption suspected
- Performance degradation >50%
- Compliance violation detected

### Rollback Steps

#### Level 1: Service Restart (5 minutes)
```bash
# 1. Restart affected service
docker-compose restart <service_name>

# 2. Verify health
docker-compose ps
curl http://localhost:<health_port>/health

# 3. Monitor for 5 minutes
watch -n 10 'docker-compose ps'
```

#### Level 2: Configuration Rollback (10 minutes)
```bash
# 1. Restore previous .env
cp .env.backup .env

# 2. Restart all services
docker-compose restart

# 3. Verify health
./scripts/health-check.sh
```

#### Level 3: Full Rollback (30 minutes)
```bash
# 1. Stop all services
docker-compose down

# 2. Restore database from backup
pg_restore -d foxhunt /backups/foxhunt_backup_<timestamp>.dump

# 3. Checkout previous git commit
git checkout <previous_commit_sha>

# 4. Rebuild and restart
docker-compose up -d --build

# 5. Verify health
./scripts/health-check.sh

# 6. Run smoke tests
./scripts/run_smoke_tests.sh
```

#### Level 4: Disaster Recovery (4-8 hours)
- Restore from off-site backup
- Recreate infrastructure from scratch
- Follow disaster recovery runbook
- Contact on-call engineer

### Rollback Testing

**Quarterly Drills**:
- Practice Level 3 rollback (full rollback)
- Measure rollback time (target: <30 minutes)
- Document lessons learned
- Update runbooks as needed
