Expand description

What to watch.

Fields§

§selectors: Vec<String>

Full wire selectors to subscribe to.

§liveliness: Vec<String>

Also watch these liveliness selectors (with history: current tokens arrive on join — no separate seed GET).

A list, not a single selector, because one selector cannot express the roster: * in the origin position never matches a verbatim service origin (RFC 03 §4 D4), so the fleet sweep <base>/v1/*/state/*/alive and <base>/v1/@catalog/state/alive are necessarily two entries. A dashboard that watches only the first renders “catalog dead” and “no entities” identically — the false verdict RFC 05 §3.1 forbids.

§stats_tick: Duration

Snapshot cadence.

§capacity: usize

Broadcast capacity: bound it to what an echo pane can drain; lag is surfaced, never hidden.

§max_keys: usize

How many distinct keys to keep statistics for. Least-recently-seen keys are dropped past this, and the drops are counted (MonitorCore::keys_evicted) — a long-running observer is bounded, and says so (RFC 09 §5.1).
