Struct Heartbeat 

pub struct Heartbeat {
    pub pc_id: String,
    pub at: DateTime<Utc>,
    pub agent_version: String,
    pub hostname: Option<String>,
    pub os_family: Option<String>,
}

Liveness ping every agent sends on a 30 s cadence (see inventory_interval / heartbeat_interval in agent_config).

hostname and os_family are enriched baseline facts so the SPA agents page has something to show as soon as the agent boots — even when the full WMI-driven HwInventory hasn’t been (or can’t be) collected. Both stay Option<String> so older agents that don’t send them still deserialize cleanly.

Fields

pc_id: String

at: DateTime<Utc>

agent_version: String

hostname: Option<String>

os_family: Option<String>

Coarse OS bucket from std::env::consts::OS — "windows", "linux", "macos". Rich OS metadata still flows through the inventory path; this is just the “agent is alive on a ” signal.
