Struct MonitorCore

Source

pub struct MonitorCore { /* private fields */ }

Expand description

The monitor’s shareable core: ingest on one side, events + snapshots on the other. Session wiring lives in Monitor; the core is pure and deterministically testable.

Implementations§

Source §

impl MonitorCore

Source

pub fn new(capacity: usize) -> Arc<MonitorCore> ⓘ

Source

pub fn ingest(&self, view: SampleView, sn: Option<u32>)

Ingest one sample: stats update + broadcast. Hot path — one lock, no tree work (that happens on the tick).

Source

pub fn node_event(&self, key: String, up: bool)

Source

pub fn tick(&self)

Rebuild the snapshot from the stats and announce it.

Source

pub fn tree(&self) -> Arc<KeyTreeSnapshot> ⓘ

The latest immutable snapshot (lock-free pull).

Source

pub fn with_stats<R>(&self, f: impl FnOnce(&StatsTable) -> R) -> R

Read access to the raw stats (hz/bw commands).

Source

pub fn dropped(&self) -> u64

Total events dropped across all lagging receivers so far.

Source

pub fn events(self: &Arc<Self>) -> EventStream

Subscribe to the event stream.
