Maintenance & Operations

Welcome to the ongoing maintenance phase of your deployed GISE application! This guide covers essential operational procedures, monitoring practices, and maintenance tasks to ensure your system runs smoothly in production.

Daily Operations​

System Health Monitoring​

Morning Health Check Routine:

# Check system status
kubectl get pods --all-namespaces
docker ps --filter "status=exited"

# Review overnight logs
tail -n 100 /var/log/application.log | grep ERROR
journalctl -u your-service --since "24 hours ago" | grep -i error

# Validate key metrics
curl -f http://localhost:8080/health
curl -f http://localhost:8080/metrics

Key Metrics to Monitor Daily​

Weekly Operations​

Performance Review​

  • Capacity Planning: Analyze resource usage trends
  • Performance Optimization: Identify and address bottlenecks
  • Cost Analysis: Review infrastructure costs and optimization opportunities

Security Assessment​

  • Vulnerability Scanning: Run automated security scans
  • Access Review: Validate user permissions and access levels
  • Backup Validation: Ensure backup systems are functioning properly

Maintenance Tasks​

  • Dependency Updates: Review and apply security patches
  • Log Rotation: Ensure log files are properly rotated and archived
  • Database Maintenance: Run optimization queries and cleanup tasks

Monthly Operations​

Comprehensive System Review​

  • Architecture Assessment: Review system architecture for improvements
  • Performance Benchmarking: Compare current performance against baselines
  • Disaster Recovery Testing: Validate backup and recovery procedures

Planning and Optimization​

  • Capacity Planning: Plan for expected growth and traffic patterns
  • Technology Updates: Evaluate new versions of dependencies and tools
  • Process Improvements: Review operational procedures and workflows

Best Practices​

Monitoring and Alerting​

# Example alert configuration
alerts:
  - name: HighCPUUsage
    condition: cpu_usage > 80%
    duration: 5m
    severity: warning
    
  - name: ServiceDown
    condition: up == 0
    duration: 1m
    severity: critical
    
  - name: HighErrorRate
    condition: error_rate > 5%
    duration: 2m
    severity: warning

Backup and Recovery​

  • Automated Backups: Daily automated database and file backups
  • Recovery Testing: Monthly recovery procedure validation
  • Documentation: Keep recovery procedures up to date

Change Management​

  • Deployment Windows: Schedule deployments during low-traffic periods
  • Rollback Plans: Always have a tested rollback strategy
  • Change Communication: Notify stakeholders of planned changes

Tools and Resources​

Monitoring Tools​

  • Prometheus & Grafana: Metrics and dashboards
  • ELK Stack: Centralized logging and analysis
  • PagerDuty: Incident management and alerting

Automation Tools​

  • Ansible: Configuration management and automation
  • Terraform: Infrastructure as Code management
  • GitHub Actions: CI/CD pipeline management
