70b57d223f
New role for gathering detailed system information including CPU, GPU,
RAM, disk, network, and hypervisor details with JSON export capabilities.
Role capabilities:
- Comprehensive hardware detection (CPU, GPU, RAM, disk, network)
- Hypervisor detection (KVM, Proxmox, LXD, Docker, Podman, VMware, Hyper-V)
- System information gathering (OS, kernel, uptime, security modules)
- Health checks and validation tasks
- JSON export with timestamped backups
- Human-readable summary generation
- Support for multiple Linux distributions
Features:
- Modular task organization by information type
- Feature toggles for selective gathering
- CLAUDE.md compliant validation tasks including:
* Disk usage monitoring (>80% warnings)
* Memory usage statistics
* Top CPU and memory processes
* System uptime tracking
* Logged users reporting
- OS-specific variable handling
- DMI/SMBIOS hardware information
- SMART disk health status
- Network interface statistics

Use cases:
- Infrastructure inventory for CMDB integration
- Capacity planning and resource optimization
- Hardware audit and compliance reporting
- Hypervisor and VM tracking
- System health monitoring
- Documentation generation
Output:
- JSON: ./stats/machines/<fqdn>/system_info.json
- Backup: ./stats/machines/<fqdn>/system_info_<timestamp>.json
- Summary: ./stats/machines/<fqdn>/summary.txt
Requirements:
- Ansible >= 2.9
- Root/sudo access for hardware information
- Packages: lshw, dmidecode, pciutils, usbutils, smartmontools, ethtool
Compliance:
- CLAUDE.md health check requirements implemented
- CIS Benchmark support for system auditing
- NIST compliance documentation support
- Security-first design with minimal system impact
