LLM Observability with Highlight and OpenLLMetry

Since Highlight natively supports OpenTelemetry, you just need to route the traces to Highlights’s OTLP endpoint and set the highlight project id in the headers:

TRACELOOP_BASE_URL=https://otel.highlight.io:4318
TRACELOOP_HEADERS="x-highlight-project=<YOUR_HIGHLIGHT_PROJECT_ID>"
