#### service_status.yml ✅ TESTED  
- **Purpose**: Generate comprehensive status reports for Docker containers
- **Features**:
  - Container health and status checks
  - Resource usage monitoring
  - JSON report generation with timestamps
  - Support for single container, pattern matching, or all containers
- **Usage**: `ansible-playbook service_status.yml -e "collect_all=true"`
- **Test Results**: Generated detailed JSON reports at `/tmp/homelab_status_*.json`

#### container_logs.yml ✅ TESTED
- **Purpose**: Collect and analyze container logs with error detection
- **Features**:
  - Flexible container selection (name, pattern, or all)
  - Configurable log lines and time range
  - Container information and resource stats
  - Automatic error pattern detection
  - Comprehensive summary reports
- **Usage**: `ansible-playbook container_logs.yml -e "collect_all=true log_lines=100"`
- **Test Results**: Successfully collected logs from 36 containers with error analysis

### 2. Backup Automation

#### backup_databases.yml ✅ TESTED
- **Purpose**: Automated database backups for PostgreSQL, MySQL, MongoDB
- **Features**:
  - Multi-database support with auto-detection
  - Configurable retention policies
  - Compression and encryption options
  - Backup verification and integrity checks
- **Usage**: `ansible-playbook backup_databases.yml -e "retention_days=30"`
- **Test Results**: Successfully created database backups with proper validation

#### backup_configs.yml ✅ TESTED
- **Purpose**: Backup Docker Compose files and application configurations
- **Features**:
  - Automatic discovery of compose files
  - Configuration file backup
  - Incremental backup support
  - Restore capability
- **Usage**: `ansible-playbook backup_configs.yml -e "backup_location=/backup/configs"`
- **Test Results**: Successfully backed up all configuration files

## Usage Examples

### Quick Status Check
```bash
ansible-playbook -i hosts.ini playbooks/service_status.yml --limit homelab -e "collect_all=true"
```

### Collect Logs for Troubleshooting
```bash
ansible-playbook -i hosts.ini playbooks/container_logs.yml --limit homelab -e "service_pattern=prometheus log_lines=200"
```

### Safe Service Restart
```bash
ansible-playbook -i hosts.ini playbooks/restart_service.yml --limit homelab -e "service_name=grafana"
```

### Backup All Databases
```bash
ansible-playbook -i hosts.ini playbooks/backup_databases.yml -e "retention_days=30"
```

## Next Steps

### Pending Tasks
1. **System Monitoring Playbooks**: Create system health and disk usage monitoring
2. **Multi-Host Testing**: Test all playbooks across all 5 homelab hosts
3. **Documentation**: Create comprehensive usage documentation
4. **Integration**: Integrate with existing homelab monitoring systems

### Recommended Enhancements
1. **Scheduling**: Add cron job automation for regular backups
2. **Alerting**: Integrate with notification systems (NTFY, Slack)
3. **Web Interface**: Create simple web dashboard for playbook execution
4. **Metrics**: Export metrics to Prometheus/Grafana
