Struct HostInfo 

pub struct HostInfo {
    pub host_id: Option<String>,
    pub host_name: Option<String>,
    pub host_ip: Option<String>,
    pub host_allocation: Option<String>,
    pub host_vcpus: Option<u32>,
    pub host_cpu_model: Option<String>,
    pub host_memory_mib: Option<u64>,
    pub host_gpu_model: Option<String>,

    pub host_storage_gb: Option<f64>,
}

Machine-level host properties collected once at startup. All fields are optional; collection failure is silently swallowed. Used in the Sentinel API registration payload (Section 9.1).

Fields

host_id: Option<String>

AWS: /sys/class/dmi/id/board_asset_tag; fallback: /etc/machine-id.

host_name: Option<String>

Hostname from gethostname(3).

host_ip: Option<String>

First non-loopback IPv4 address from getifaddrs(3).

host_allocation: Option<String>

"dedicated" or "shared". Heuristic TBD; currently always None.

host_vcpus: Option<u32>

Count of logical CPUs from /proc/cpuinfo processor entries.

host_cpu_model: Option<String>

CPU model string from /proc/cpuinfo.

host_memory_mib: Option<u64>

Total physical RAM: MemTotal / 1024 from /proc/meminfo.

host_gpu_model: Option<String>

Name of the first detected GPU/NPU/TPU.

host_gpu_count: Option<u32>

Count of detected GPUs.

host_gpu_vram_mib: Option<u64>

Sum of vram_total_bytes / 1_048_576 across all GPUs. Serialized as host_gpu_memory_mib to match the Sentinel API field name.

host_storage_gb: Option<f64>

Sum of block device capacities in GB (non-loop, non-ram devices).
