//! Datastream → dashboard adapter.
|
|||
|
|
//!
|
|||
|
|
//! Binds the UDP sink the demo cluster ships to (the same wire the dumb
|
|||
|
|
//! `swactor-datastream-collector` reads), **demultiplexes** the per-node frames,
|
|||
|
|
//! and drives the dashboard's *existing* views from them — no bespoke UI:
|
|||
|
|
//!
|
|||
|
|
//! * the single-node **Overview / Actors** page (`/`) via a synthesized
|
|||
|
|
//! [`RuntimeStats`] (each datastream channel becomes one synthetic actor row);
|
|||
|
|
//! * the canonical **Distribution** connection-graph page
|
|||
|
|
//! (`/plugin/distribution`, [`crate::DISTRIBUTION_PAGE_HTML`]) via a
|
|||
|
|
//! [`DistributionNodeSnapshot`] rebuilt from the selected node's membership —
|
|||
|
|
//! so it renders the exact SWIM graph a live node shows;
|
|||
|
|
//! * a cross-node **Fleet** table (`/plugin/vastai`) served in the same
|
|||
|
|
//! dashboard chrome (nav bar + palette), not a separate app.
|
|||
|
|
//!
|
|||
|
|
//! Process output and membership transitions are emitted as `tracing` events so
|
|||
|
|
//! they flow through the dashboard's activity-log path.
|
|||
|
|
//!
|
|||
|
|
//! A node is only shown while it is *live* (has shipped a frame within
|
|||
|
|
//! [`NODE_TTL`]); a node that stops streaming drops out of every view, so a
|
|||
|
|
//! restarted/departed node leaves no ghost in the graph or the fleet table.
