Observability Setup (lumi-api)

apps/lumi-api exposes operational endpoints under /internal/*.

Endpoints

• GET /internal/isAlive
• GET /internal/isReady
• GET /internal/prometheus

Local verification

curl -i http://localhost:8080/internal/isAlive
curl -i http://localhost:8080/internal/isReady
curl -s http://localhost:8080/internal/prometheus | head -50

Repo boundaries

• Metrics path is /internal/prometheus (do not invent new paths).
• Kafka is not used in lumi-api; do not add Kafka readiness checks unless explicitly decided.

Nais manifest essentials
