Struct DiskMetrics 

pub struct DiskMetrics {
    pub device: String,
    pub model: Option<String>,
    pub vendor: Option<String>,
    pub serial: Option<String>,
    pub device_type: Option<DiskType>,
    pub capacity_bytes: Option<u64>,
    pub mounts: Vec<DiskMountMetrics>,
    pub read_bytes_per_sec: f64,
    pub write_bytes_per_sec: f64,

}

Per-device disk metrics: static identity (cached once) + dynamic throughput and filesystem space (polled each interval).

Fields

device: String

model: Option<String>

e.g. “Samsung SSD 870 EVO 1TB”, from /sys/block/<dev>/device/model.

vendor: Option<String>

e.g. “ATA”, from /sys/block/<dev>/device/vendor.

serial: Option<String>

World-Wide ID or serial, from /sys/block/<dev>/device/wwid or serial.

device_type: Option<DiskType>

capacity_bytes: Option<u64>

Total raw device capacity in bytes (/sys/block/<dev>/size × 512).

mounts: Vec<DiskMountMetrics>

read_bytes_per_sec: f64

write_bytes_per_sec: f64

read_bytes_total: u64

Cumulative bytes read since boot (raw /proc/diskstats sector count × 512). Matches Python resource-tracker’s disk_read_bytes column.

write_bytes_total: u64

Cumulative bytes written since boot (raw /proc/diskstats sector count × 512). Matches Python resource-tracker’s disk_write_bytes column.
