Struct ProcessSnapshot 

pub struct ProcessSnapshot {
    pub pid: u32,
    pub name: String,
    pub cpu_pct: f64,
    pub rss_bytes: i64,
    pub disk_read_bytes_per_sec: Option<f64>,
    pub disk_written_bytes_per_sec: Option<f64>,
}

Single process row inside ProcessPerf. Mirrors the shape of the agent’s self-perf fields on Heartbeat so existing formatters (em-dash for nulls etc.) keep working on the SPA.

Fields

pid: u32

PID — u32 matches Windows DWORD and is wide enough for Linux’s 22-bit space too.

name: String

Image name as sysinfo reports it (basename on Linux, “program.exe” on Windows). NOT the full path — that lives in inventory if an operator needs to disambiguate two identically named processes.

cpu_pct: f64

Percent-of-one-core, same convention as Heartbeat::agent_cpu_pct. A worker pinning two cores reports 200.0 here; divide by the host’s core count for a host- normalised view.

rss_bytes: i64

Resident set size in bytes — sysinfo’s Process::memory(). i64 (not u64) so the projector binds cleanly via sqlx::query! against an INTEGER column.

disk_read_bytes_per_sec: Option<f64>

Disk read rate, B/s, computed agent-side by diffing successive cumulative Process::disk_usage().total_read_bytes and dividing by elapsed wall time. None on the very first tick for a freshly-tracked PID (no prior sample to diff) and after any cadence change that resets the baseline.

disk_written_bytes_per_sec: Option<f64>
