backup_configs.yml

Purpose: Configuration and data backup automation Features:

• Docker compose file backup
• Configuration directory archival
• Service-specific data backup
• Incremental backup support
• Backup inventory tracking
• Automated cleanup of old backups

Usage:

# Backup configurations
ansible-playbook -i hosts.ini playbooks/backup_configs.yml

ansible-playbook -i hosts.ini playbooks/backup_configs.yml -e "include_secrets=true"

📊 Monitoring & Alerting

health_check.yml

Purpose: Comprehensive system health monitoring Features:

• System metrics collection (uptime, CPU, memory, disk)
• Docker container health assessment
• Critical service verification
• Network connectivity testing
• Tailscale status monitoring
• JSON health reports
• Alert integration for critical issues

Tested Results:

• ✅ homelab: 29/36 containers running, all services healthy
• ✅ pi-5: 4/4 containers running, minimal resource usage
• ✅ vish-concord-nuc: 19/19 containers running, 73% disk usage
• ✅ homeassistant: 11/12 containers running, healthy
• ✅ truenas-scale: 26/31 containers running, 1 unhealthy container

Usage:

# Health check across all hosts
ansible-playbook -i hosts.ini playbooks/health_check.yml

# Check specific host group
ansible-playbook -i hosts.ini playbooks/health_check.yml --limit debian_clients

system_metrics.yml

Purpose: Real-time system metrics collection Features:

• Continuous metrics collection (CPU, memory, disk, network)
• Docker container metrics
• Configurable collection duration and intervals
• CSV output format
• Baseline system information capture
• Asynchronous collection for minimal impact

Usage:

# Collect metrics for 60 seconds
ansible-playbook -i hosts.ini playbooks/system_metrics.yml

# Custom duration and interval
ansible-playbook -i hosts.ini playbooks/system_metrics.yml -e "metrics_duration=300 collection_interval=10"

alert_check.yml

Purpose: Infrastructure alerting and monitoring system Features:

• Configurable alert thresholds (CPU, memory, disk, load)
• Docker container health monitoring
• Critical service status checking
• Network connectivity verification
• NTFY notification integration
• Alert severity classification (critical, warning)
• Comprehensive alert reporting
