Live Dashboard API

stdlib HTTP + Server-Sent Events server that streams the running stats from test_record_instance.

start_dashboard()

from je_load_density import start_dashboard, stop_dashboard

start_dashboard(
    host="127.0.0.1",
    port=8765,
    refresh_seconds=1.0,
    window_seconds=10.0,
)

Parameters:

Parameter	Default	Description
`host`	`"127.0.0.1"`	Bind address.
`port`	`8765`	Bind port.
`refresh_seconds`	`1.0`	SSE push interval.
`window_seconds`	`10.0`	Sliding window for `rps` / `avg_ms` calculation.

Returns: LiveDashboardServer.

stop_dashboard()

Cleanly shuts down the running server (idempotent).

snapshot_metrics()

from je_load_density import snapshot_metrics

payload = snapshot_metrics(window_seconds=10.0)

Returns the dict served by /snapshot:

totals — overall counts (re-used from build_summary)
latency_overall— overall percentiles
per_name — per-endpoint stats
rps — rolling RPS over window_seconds
avg_ms — rolling mean latency
ts — Unix time of the snapshot

Endpoints

URL	Returns
`GET /`	Single-page HTML.
`GET /events`	`text/event-stream` (one snapshot per `refresh_seconds`).
`GET /snapshot`	One-shot JSON.

Action-JSON commands
