Maintenance Guide¶

This guide covers routine maintenance procedures, updates, and best practices for AIDDDMAP deployments.

Routine Maintenance¶

1. Database Maintenance¶

Regular Backups¶

# Automated daily backup
0 0 * * * pg_dump -Fc aidddmap > /backups/aidddmap_$(date +%Y%m%d).dump

# Verify backup integrity
pg_restore --list /backups/aidddmap_latest.dump

# Test restore (to separate database)
pg_restore -C -d aidddmap_test /backups/aidddmap_latest.dump

Database Optimization¶

-- Regular vacuum
VACUUM ANALYZE;

-- Update statistics
ANALYZE;

-- Index maintenance
REINDEX DATABASE aidddmap;

2. Cache Management¶

Redis Maintenance¶

# Monitor memory usage
redis-cli info memory

# Clear specific cache
redis-cli DEL cache:key

# Backup Redis data
redis-cli SAVE

3. Log Management¶

Log Rotation¶

{
  "logs": {
    "rotation": {
      "frequency": "daily",
      "maxSize": "100M",
      "maxFiles": 30,
      "compress": true
    },
    "paths": [
      "/var/log/aidddmap/api.log",
      "/var/log/aidddmap/worker.log",
      "/var/log/aidddmap/error.log"
    ]
  }
}

Log Analysis¶

# Search for errors
grep -i error /var/log/aidddmap/error.log

# Monitor real-time logs
tail -f /var/log/aidddmap/api.log

System Updates¶

1. Version Control¶

Update Process¶

# Pull latest changes
git pull origin main

# Install dependencies
npm install

# Run migrations
npm run migrate

# Build assets
npm run build

Rollback Procedure¶

# Revert to previous version
git checkout v1.2.3

# Rollback database
npm run migrate:rollback

# Rebuild
npm run build

2. Dependency Updates¶

NPM Updates¶

# Check outdated packages
npm outdated

# Update packages
npm update

# Update specific package
npm update @aidddmap/core

Security Updates¶

# Check for vulnerabilities
npm audit

# Fix vulnerabilities
npm audit fix

Performance Optimization¶

1. Database Optimization¶

Index Management¶

-- Create indexes
CREATE INDEX idx_users_email ON users(email);
CREATE INDEX idx_datasets_owner ON datasets(owner_id);

-- Monitor index usage
SELECT schemaname, tablename, indexname, idx_scan, idx_tup_read
FROM pg_stat_user_indexes;

Query Optimization¶

-- Analyze slow queries
EXPLAIN ANALYZE SELECT * FROM large_table WHERE condition;

-- Update statistics
ANALYZE table_name;

2. Cache Optimization¶

Cache Settings¶

// cache-config.ts
export default {
  ttl: 3600,
  maxItems: 10000,
  updateAgeOnGet: true,
  checkperiod: 600,
};

Cache Monitoring¶

interface CacheMetrics {
  hits: number;
  misses: number;
  keys: number;
  ksize: number;
  vsize: number;
}

Security Maintenance¶

1. Certificate Management¶

SSL Certificate Renewal¶

# Check certificate expiration
openssl x509 -enddate -noout -in /etc/ssl/certs/aidddmap.crt

# Renew certificate (using certbot)
certbot renew

Key Rotation¶

interface KeyRotation {
  frequency: "monthly" | "quarterly";
  algorithm: string;
  keySize: number;
  notifyBefore: string;
}

2. Security Audits¶

Access Review¶

{
  "audit": {
    "frequency": "monthly",
    "checks": [
      "user_permissions",
      "api_keys",
      "service_accounts",
      "encryption_keys"
    ],
    "notification": {
      "email": "security@yourdomain.com"
    }
  }
}

Security Scanning¶

security_scan:
  schedule: "0 0 * * 0" # Weekly
  targets:
    - dependencies
    - docker_images
    - api_endpoints
    - configuration
  alerts:
    - email: security@yourdomain.com
    - slack: "#security-alerts"

Backup Procedures¶

1. Data Backup¶

Backup Configuration¶

{
  "backup": {
    "database": {
      "frequency": "daily",
      "retention": "30d",
      "type": "full"
    },
    "files": {
      "frequency": "daily",
      "retention": "7d",
      "excludes": ["temp", "cache"]
    },
    "encryption": {
      "algorithm": "AES-256-GCM",
      "enabled": true
    }
  }
}

Backup Verification¶

interface BackupVerification {
  checksum: string;
  size: number;
  timestamp: Date;
  status: "success" | "failure";
  details: Record<string, any>;
}

2. Disaster Recovery¶

Recovery Plan¶

recovery_steps:
  1: "Stop all services"
  2: "Restore database backup"
  3: "Restore file backups"
  4: "Verify data integrity"
  5: "Start services"
  6: "Run health checks"

Recovery Testing¶

# Test database restore
pg_restore -C -d aidddmap_test backup.dump

# Verify application startup
npm run verify-deployment

Monitoring & Alerts¶

1. System Monitoring¶

Health Checks¶

interface HealthCheck {
  service: string;
  status: "healthy" | "degraded" | "unhealthy";
  lastCheck: Date;
  metrics: {
    uptime: number;
    responseTime: number;
    errorRate: number;
  };
}

Performance Metrics¶

{
  "metrics": {
    "collection": {
      "interval": "1m",
      "retention": "30d"
    },
    "alerts": {
      "cpu_threshold": 80,
      "memory_threshold": 85,
      "disk_threshold": 90
    }
  }
}

2. Alert Configuration¶

Alert Rules¶

alerts:
  - name: high_error_rate
    condition: error_rate > 0.05
    duration: 5m
    severity: critical

  - name: low_disk_space
    condition: disk_free < 10GB
    duration: 15m
    severity: warning

Best Practices¶

1. Documentation¶

• Keep maintenance procedures updated
• Document all configuration changes
• Maintain runbooks for common issues
• Record maintenance history

2. Testing¶

• Test backups regularly
• Verify recovery procedures
• Validate configuration changes
• Run security scans

3. Automation¶

• Automate routine tasks
• Use configuration management
• Implement continuous monitoring

4. Communication¶

• Notify users of maintenance
• Document downtime procedures
• Maintain status page
• Update stakeholders

Next Steps¶

1. Review monitoring setup
2. Configure backup procedures
3. Implement security measures
4. Plan scaling strategy
5. Set up alerts
