Monitoring and Logging Strategy

Why Monitor Your Personal Cloud?

• Performance: Identify bottlenecks and resource issues
• Security: Detect unauthorized access attempts
• Reliability: Proactive issue detection
• Capacity Planning: Understand growth patterns

MCT Services Monitoring Stack

Our monitoring approach uses:

• Prometheus: Metrics collection and storage
• Grafana: Visualization and dashboards
• Loki: Log aggregation
• Node Exporter: System metrics
• cAdvisor: Container metrics

Key Metrics to Monitor

System Metrics

• CPU usage and load average
• Memory utilization
• Disk space and I/O
• Network traffic

Container Metrics

• Container resource usage
• Container health status
• Restart counts
• Image vulnerabilities

Application Metrics

• Response times
• Error rates
• User activity
• Database performance
