- Add static/otel-rum.js: a framework-free browser script that captures
uncaught errors, unhandled promise rejections and failed resource loads,
translating them into OTLP log records POSTed to the existing /v1/logs
endpoint (source: frontend attribute) so they flow through the same
history/search/issue pipeline as backend telemetry.
- Add correlation-id support: traceHeaders() (manual) and same-origin
fetch auto-instrumentation inject a W3C traceparent header, so a
frontend error and the backend spans it triggered share a trace id and
can be found together via GET /api/traces/{traceId}.
- Add CORS handling (withCORS in cmd/server/main.go) on the OTLP HTTP
endpoints, required for any browser-origin POST.
- Add an optional shared ingest key (OTEL_INGEST_KEY, via '?key=' or
X-Otel-Ingest-Key) and a per-IP rate limit (20 rps/burst 50) on OTLP
HTTP ingestion, to scope/protect a public endpoint fed by a browser
script. Verified end-to-end (CORS preflight, cross-origin POST, ingest
key enforcement, rate limiting) against a running server.
- Serve static/otel-rum.js and agents_example.md as static HTTP routes so
both the script and the agent instructions doc are fetchable directly
from the base URL.
- Ignore the separately-cloned otel-ui/ frontend repo (has its own .git;
not meant to be nested into this repo's history).
