Dashboard

Everything under Quiote\Telemetry\Dashboard.

Classes

Class	Description
`Bars`	Renders a value/ceiling ratio as a fixed-width filled/empty block bar — the dashboard’s stand-in for a Gauge widget (`symfony/tui` has none; see `Spark`’s docblock for the same widget-gap note).
`ChartWidget`	A leaf widget that renders a numeric series as a multi-row bar chart, filling whatever height and width it is assigned at render time.
`DashboardSnapshot`	An immutable read of `DashboardState` at one point in time — everything `DashboardView` needs to draw one frame, with no further computation or I/O required.
`DashboardState`	The rolling in-memory store fed by `OtlpReceiver`’s decoded batches and read by the render loop via `DashboardState::snapshot()`.
`DashboardView`	Pure state -> widget-tree builder for the dashboard’s live view: no I/O, no `symfony/tui` runtime calls (`Tui::add()`/`requestRender()` etc.) — only this class and `TelemetryDashboardCommand` touch `Symfony\Component\Tui\*` directly, containing the experimental package’s surface to two files.
`HttpMessageParser`	Minimal, bounded HTTP/1.1 request parser for the dashboard’s OTLP receiver (see `OtlpReceiver`).
`MalformedRequestException`	Thrown by `HttpMessageParser` for anything outside the narrow OTLP/HTTP shape the OTel PHP exporter sends (see that class’s docblock).
`OtlpDecoder`	Decodes OTLP `ExportTraceServiceRequest`/`ExportMetricsServiceRequest` protobuf (or JSON) payloads — exactly what the OTel PHP OTLP/HTTP exporter sends, per `telemetry.otlp.protocol` — into plain `ReceivedSpan`/ `ReceivedMetric` value objects.
`OtlpReceiver`	A minimal OTLP/HTTP receiver: binds a TCP socket and services it on the global Revolt event loop, exactly the pattern `symfony/tui`’s own `Terminal::start()` uses for STDIN (`EventLoop::onReadable()`) — so this runs cooperatively alongside a `Tui::run()` loop in the same process, no threads or second process needed.
`ParsedHttpRequest`	The result of `HttpMessageParser::tryParse()` — method, path, headers (lower-cased names), and the fully-buffered request body.
`ReceivedDataPoint`	A single data point within a `ReceivedMetric`.
`ReceivedMetric`	A metric decoded from an OTLP `ExportMetricsServiceRequest` by `OtlpDecoder`.
`ReceivedSpan`	A span decoded from an OTLP `ExportTraceServiceRequest` by `OtlpDecoder`, flattened into plain PHP values so nothing downstream (DashboardState, DashboardView, tests) needs to touch protobuf types.
`RingBuffer`	A fixed-window, per-second time series.
`RouteStats`	Per-route aggregates (count, avg latency, error %, cache-hit %, last seen) for the dashboard’s route table.
`Spark`	Renders a numeric series as a Unicode block-glyph bar chart, using eighth blocks (`▁▂▃▄▅▆▇█`) per character row to get sub-row vertical resolution across an arbitrary number of text rows.
`TextSanitizer`	Strips terminal-escape introducer bytes from telemetry-derived strings (span names, status messages, route labels, attribute values) before they reach a `TextWidget`.
